Beneath Our Bridges

Our largest aquarium, this exhibit depicts the myriad life that thrives around large man-made structures installed around the Chesapeake Bay. Hard surfaces exposed to natural waters often team with life, serving as a stable place to attach and steady against shifting tides and currents. Sessile (attached) life attracts larger free-swimming animals like game fish, marine mammals and sea turtles - there to feed on the rich life that abounds.

Our bridges span the deep, open waters of the bay. Oceangoing ships follow the channels created in a time before the Susquehanna River succumbed to rising seas. Massive jetties and bulkheads attempt to stave off rising seas or prevent shoreline erosion. Despite human influences, the bay continues to demonstrate amazing resilience.
 
Only a select few of these species are on exhibit at any time, though all are representative of Beneath Our Bridges habitats.

American conger eel

Scientific name: 
Conger oceanicus

Location: Western Atlantic, from Cape Cod, MA to Northeastern FL and Northern Gulf of Mexico. Reported Eastern Atlantic in St. Helena and Northwest Atlantic Canada.

Habitat: Deep water near the bottom, as deep as 477 m but typically 75-150 m; shallow inshore waters; often found close to shore near docks

Key Characteristics: Most eels may have similar form but the size of the mouth and lengths of the fins make the Conger eel different. Firstly, the mouth gape continues back only as far as the middle or rear edge of the eye. Secondly, the body of the Conger eel is considered moderately thick and strong. Finally, the tail tip is soft and rounded. The Conger is scaleless.

Coloration: Usually dark gray-green with small speckles of rusty-red color; additional coloration – gray, brown, black, steel-blue, olive-green or reddish-brown; typically dingy white below.

Feeding Habits: Main diet made up of fishes, also shrimps, small shellfish, octopus and squid. They typically wait to ambush their prey and are bottom-feeders. They use their very wide mouths and extremely sharp teeth to hunt and feed.

Reproduction: External fertilization- eggs are simply deposited in the open sea. The female breeds once during its life span then dies. It is recorded that American conger become sexually mature in the summer off the coast of southern New England while European conger in captivity can do so every month except October and November. Spawning occurs out from the coast in more open waters. *www.gma.org

Maximum Length (in inches or feet): 7.5 ft max length, 89 lbs weight

Predators: Finfish like Bluefish

Importance to Humans: These eels are an enticing to hunt. Some conger eels are consumed as part of Asian cuisine.

Conservation Status: Secure, not at risk

They use this sense to locate prey buried in the sand.

Reproduction: ovoviviparous. Males teeth change from rounded with flat blunt surface to long sharp cusps that curve in toward corners of mouth; this enables them to grip onto the females during mating. Annual mating season from September or October to April though ovulation doesn’t occur until late March or early April.

Maximum length (in inches or feet): 2 ft

Predators: many shark species (white shark, tiger shark, bull shark to name a few). Alligators may eat freshwater species.

Blue Crab

Blue crab

Scientific name: 
Callinectes sapidus 


Growth stages of a blue crab
Blue Crab Juvenile
Blue Crab Growth

Distribution: Native to western edge of Atlantic Ocean from Nova Scotia to Agentina and around entire coast of the Gulf of Mexico. Estuaries along east coasts of North and South America. Also been seen in coastal waters of Holland and Denmark. It has been introduced (via transfer in ballast water on ships) to Japanese and European waters.

Habitat: Bottom-dwellers; marine, estuary, coastal, brackish

Key characteristics for distinction: Five pairs of legs, the first pair is modified as pinchers (claws) while the last four pairs are walking legs (the last pair paddle-shaped to aide in swimming). The carapace is drawn out on each side into a large spine. Fully grown, the spine may be as large as 8 inches wide. To help identify against other crab species in the area, count the number of frontal teeth on the carapace. C. sapidus has four frontal teeth while C. ornatus has six. Crabs molt to grow.

Coloration: Back of crab is dark or brownish green. Abdomen and lower legs are white. Claws are various shades of blue except females have red-tipped claws.

Feeding habits/specializations: Omnivore – bivalves, annelids, small fish, plants and almost any other food item it can find along the bottom including carrion and other waste. Blue crabs are scavengers and help “clean up” the water by feeding on most things.

Reproduction: Females only mate one in their lifetime. Mating occurs from May through October. Males will cradle a soft-shelled female for days while he looks for a protected area for her final molt. Once she has molted, the pair mate. After mating, the females travel to southern part of Chesapeake using the tides to migrate to areas of higher salinity. The eggs are fertilized with sperm stored from the only mating (which could be from months to almost a year ago). Up to 2 million eggs may be produced in a single brood while one female can produce of 8,000,000 eggs in a lifetime. The eggs appear as an orange mass on her pleopods for about two weeks before being released between November and December. The eggs hatch and float into the mouth of the bay for about four to five weeks until they make their way back into the bay.

Maximum length (in inches or feet): Carapace width of 9.1 in

Predators: eels, drums, striped bass, spot, trout, some sharks, humans, cownose stingrays, birds and sea turtles.

Importance to humans: Valuable fishery/commercial. Aide in “cleaning up” the water due to their feeding habits.

Conservation status: safe but under management plans throughout the range of the species. Watched carefully as a major commercial fishery.

Fun fact: Blue crabs are Maryland's state crustacean. Males have blue claws and narrow abdominal apron; females have red-tipped claws and broad apron.

Gag Grouper

Gag grouper

Scientific name: 
Mycteroperca microlepis

Habitat: Marine; brackish; reef-associated; oceanodromous. Juveniles occur in estuaries and seagrass beds; adults are usually found offshore on rocky bottom; occasionally inshore on rocky or grassy bottom. It is the most common grouper on rocky ledges in the eastern Gulf of Mexico. Adults are either solitary or in groups of 5 to 50 individuals. *fishbase.org

Key characteristics for distinction: Dorsal spines (total): 11; Dorsal soft rays (total): 16-18; Anal spines: 3; Anal soft rays: 10 - 12. …. Oblong-shaped elongate body. The head is long while the mouth is large with a protruding lower jaw. The bases of the dorsal and anal fins are covered with scales and thick skin. The caudal fin is large and has a slightly concave margin. This grouper is often confused with the black grouper (M. bonaci), however it is has some distinguishing characteristics. These include the shape of the caudal fin - the gag grouper has a slightly concave margin along the posterior edge of the caudal fin while the black grouper has square-shaped caudal fin *flmnh.ufl.edu

Coloration: Coloration is dependent on the sex and age… Adult females and juveniles are generally brownish grey with dark vermiculation; camouflage phase has 5 dark brown saddles separated by short white bars below the dorsal fin; large males sometimes display a "black-belly" and "black-back" phase; black-belly phase is mostly pale grey, with faint dark reticulations below soft dorsal fin, belly and ventral part of the body above anal fin black, as are margin of the soft dorsal fin, central rear part of caudal fin and rear margins of pectoral and pelvic fins *fishbase.org

Feeding habits/specializations: feed mainly on fishes, some crabs, shrimps, and cephalopods. Juveniles feed mainly on crustaceans that live in shallow grass beds. There are two well-developed canine teeth present anteriorly in each jaw. These are quite effective for holding prey items.

Reproduction: Similar to other serranids, gag grouper are protogynous hermaphrodites. They begin life as female, however after a few years of spawning as a female, some gag groupers change sex, becoming functional males. This transition generally occurs at 10-11 years of age corresponding to lengths of 37-39 inches. Spawning occurs from January through May in the Gulf of Mexico and the South Atlantic Bight at offshore spawning grounds. There is a major spawning ground on the west Florida Shelf. The fertilized eggs are pelagic and transparent, containing a single oil globule. Eggs hatch after approximately 45 hours at water temperatures of 70ºF (21ºC) (laboratory study). The kite-shaped, as postlarvae they migrate from the spawning grounds to inshore seagrasses, mangroves, oyster reefs and salt marshes. Juveniles remain in these locations for approximately 3-5 months migrating to offshore reefs. *source flmnh.ufl.edu

Key characteristics for distinction: The horseshoe crab is a primitive-looking arthropod with a hard, brownish-green exoskeleton and a spike-like tail. Widely spaced eyes that look like bumps on the top of the shell. Five pairs of jointed legs. Gills have folds of membranes that look like leaves of a book.

Coloration: brownish-green exoskeleton; juveniles are sand-colored

Feeding habits/specializations: Eats mostly worms and mollusks such as razor clams and soft shell clams. Because they lack jaws, horseshoe crabs use the spiny bases of their legs to crush and grind their food, then push it into their mouths. Spends most of its time rooting through bottom sediments looking for food.

Reproduction: Spawning takes place in spring and summer (peaking in May-June), usually during evening high tides when the moon is full or new. Large numbers of adults crawl up onto sandy, protected beaches to mate and lay eggs. Females lay clusters of about 4,000 greenish eggs in the sand around the high-tide mark. They return to the beach to lay more eggs during high tides throughout the season. Eggs take about one month to hatch.

Maximum length (in inches or feet): 2 ft

Feeding habits/specializations: As a sedentary invertebrate, primarily feeds on algae. Bits of algae are a common food that urchins snag out of the water. The tube feet, spines, and pedicellariae are used to grab the food and aid it into the mouth. In addition to grabbing food out of the water, it scrapes algae off the rocks or substrate. It's mouth consists of a strong jaw piece called Aristotle's lantern. The mouthpiece itself has five bony teeth that are instrumental in scraping the algae off the substrate. While any algae will satisfy the appetite of the purple sea urchin, this species prefers the giant kelp Macrocystis pyrifera.

Reproduction: January, February, and March are the primary reproductive months of S. purpuratus. It has been noted, however, that ripe individuals can be found even into the month of July. Purple sea urchins reach sexual maturity at the age of two years. At this time they are about 25mm in diameter or greater. Once sexually mature, females and males release their gametes into the ocean where fertilization occurs. The fertilized egg then settles and begins to grow into an adult.

Maximum length (in inches or feet): 4 in

Predators: sea otters, sunflower stars, California sheephead

Importance to humans: Purple sea urchins feed on the giant kelp, as mentioned previously. In their feeding, they can destroy entire forests of kelp. These kelp forests are commercially important for fisheries. They are even more important in that the blades of the kelp can be harvested for algin.

Red_Drum-DR-010

Red drum

Scientific name: 
Sciaenops ocellatus

Habitat: Marine; brackish; demersal; oceanodromous. Occurs usually over sand and sandy mud bottoms in coastal waters and estuaries. Abundant in surf zone.

Key characteristics for distinction: The body of the red drum is elongate with a slightly arched back and sloping head. It has a blunt snout with a large sub-terminal mouth similar to most species in the Sciaenidae family. There are two dorsal fins, the first of which has ten hard spines and the second with one hard spine and numerous soft rays. The caudal fin is slightly concave. The red drum can be distinguished from the closely related black drum (Pogonias cromis) by its lack of barbels.

Coloration: The red drum is usually a copper reddish color. Coloration can also range from a deep dark copper to an almost silvery sheen. The ventral side is usually a lighter color to almost white. Red drums have a distinctive black spot near the base of the tail. One spot is most common however some individuals exhibit several spots.

Feeding habits/specializations: crustaceans, mollusks and fishes. Females can produce one-half to two million eggs per season with each egg measuring approximately 1.0mm in diameter. Eggs hatch at approximately 28-30 hours after spawning resulting in larvae that are about 6-8 mm standard length.

Reproduction: Spawning usually takes place from mid-August to mid-November, often near tidal inlets.

Maximum length (in inches or feet): 61 in

Predators: The main predator of the red drum is humans. Other predators include birds of prey including ospreys, as well as larger fishes. The black tail spot is thought to be used as mechanism to confuse predators into attacking the tail instead of the head.

Importance to humans: fishing/minor commercial

Conservation status: not evaluated

Fun fact: Drums are known to make a characteristic drumming noise during spawning.

Scrawled cowfish

Scientific name: 
Acanthostracion quadricornis

Habitat: primarily in seagrass beds to depths of 262 feet (80 m).

Key characteristics for distinction: deep, covered with hexagonal-shaped dermal plates that are securely fused together to form a "carapace". There is a pair of spines projecting from in front of the eyes, similar in appearance to cow horns, hence its common name of "cowfish". A second pair of spines is located at the rear corners of the carapace. The carapace terminates around the base of the soft dorsal and anal fins. The terminal mouth is small with fleshy lips. Pelvic fins and spiny dorsal fin are absent. The caudal fin is rounded, truncate, or slightly produced ventrally or dorsally.

Coloration: typically grayish-brown to yellowish-green with numerous blackish-blue to bright blue irregular bars and spots. There are dark spots or blotches on the body. In addition, there are three to four more or less parallel blue stripes on the cheek which can be prominent, however some individuals appear relatively plain, lacking these prominent markings.

Feeding habits/specializations: sessile invertebrates such as tunicates, gorgonians, and anemones in addition to slow-moving crustaceans, sponges, hermit crabs and marine vegetation.

Reproduction: Spawning has been documented off Venezuela during the months of January through February and June through September. Eggs are released in pelagic waters with the larval stage is completed while still pelagic, with juveniles eventually settling out of the water column.

Maximum length (in inches or feet): 22 in

Predators: Larger fish are potential predators of the scrawled cowfish, however it may be undesirable as a prey item due to its protective external armor, the carapace.

Importance to humans: considered an excellent food fish and is often marketed fresh. However, it has been implicated in boxfish poisoning when not prepared properly. There have also been reports of ciguatera poisoning from eating the flesh of this fish.

Conservation status: not evaluated

Fun fact: There is a pair of spines projecting from in front of the eyes, similar in appearance to cow horns, hence its common name of "cowfish.”

Scrawled filefish

Scientific name: 
Aluterus scriptus

Habitat: Associated with lagoons and seaward reefs. Also sometimes observed swimming under floating objects with juveniles traveling with weed rafts in the open ocean until reaching a large size.

Key characteristics for distinction: It is an elongate, strongly compressed filefish. The upturned mouth is small and opens above center line and the snout is concave. The openings of the gills are oblique and the pelvic fin is absent. The caudal fin is long and rounded with a back edge that is often ragged.

Coloration: Adult scrawled filefish are olive brown to gray in color with irregular blue spots and short lines as well as small black spots while the juveniles may be yellowish brown with dark spots.

Feeding habits/specializations: feeds on algae, seagrass, hydrozoans, gorgonians, colonial anemones, and tunicates.

Reproduction: breed in groups consisting of one male and two to five females. The females lay demersal eggs in safe areas such as a depression in the sand, then the male comes along and fertilizes them. The male or female will guard these fertilized eggs from predators and will attack any intruders that approach too closely. Upon hatching, the female will take care of the young fish.

Maximum length (in inches or feet): 43 in

Predators: Larger fish are potential predators of the scrawled filefish including dolphinfish (Coryphaena hippurus) and bluefin tuna (Thunnus thynnus).

Importance to humans: gamefish in some locations; if flesh is eaten, caution should be taken as there have been reports of ciguatera poisoning.

Conservation status: not evaluated

Fun fact: When threatened, the filefish dives into a crevice, wedging itself by erecting the dorsal spine on its head. This large spine is locked into place by the smaller spine behind it while another spine located on the belly extends to further securely wedging the fish in the crevice.

121-Scup

Scup

Scientific name: 
Stenotomus chrysops

Habitat: Marine; demersal; oceanodromous. Occurs usually in schools inshore in summer and offshore in winter.

Key characteristics for distinction: deep-bodied (deeper from back to belly than they are wide) and spiny fins. Scup’s front teeth are very narrow, almost conical, and they have two rows of molars in the upper jaw. Longspine porgy look similar to scup, but can be easily identified by the elongated spines on their backs.

Coloration: dusky brown with bright silvery reflections below; adult fins are mottled with dark brown, and young scup fins may be faintly barred.

Feeding habits/specializations: Feeds on amphipods, worms, sand dollars and young squid.

Reproduction: They spawn over weedy or sandy areas. Scientists believe scup spawn in the morning, unlike most fish that spawn at night. Females release an average of 7,000 eggs, which are fertilized externally.

Maximum length (in inches or feet): 18 in

Predators: other larger fish; humans

Importance to humans: Reports of ciguatera poisoning. Fishing/commercial

Conservation status: not evaluated

117-Sheepshead

Sheepshead

Scientific name: 
Archosargus probatocephalus

Habitat: inshore around rock pilings, jetties, mangrove roots, and piers as well as in tidal creeks, the euryhaline sheepshead prefers brackish waters.

Key characteristics for distinction: oval-shaped, deep body with a blunt snout and small, nearly horizontal mouth. The posterior nostril is slit-like in appearance. Dorsal and anal fins include stout, short spines. The second spine of the anal fin is enlarged. Pectoral fins are long, extending beyond the anal opening when appressed (pressed close to the body). The caudal fin is shallowly forked.

Coloration: The adult sheepshead is silvery to greenish-yellow with an olive back. There are five or six dark vertical crossbars along each side, which are most distinct in young individuals. The caudal and pectoral fins are greenish while the dorsal, anal, and ventral fins are dusky or black.

Feeding habits/specializations: Teeth of the sheepshead include well-defined incisors, molars, and grinders. At the front of the jaw are the incisor-like teeth. The molars are arranged in three rows in the upper jaw and two rows in the lower jaw. Heavy, strong teeth are necessary for crushing and grinding the shelled animals that are prey for this fish. Feeding on invertebrates, small vertebrates and occasional plant material.

Reproduction: Adults migrate to offshore waters to spawn, later returning to nearshore waters and estuaries. Spawning frequency ranges from once a day to once every 20 days. Little is known regarding spawning behavior. Depending upon their condition, females may produce from 1,100 to 250,000 eggs per spawning event. One study determined that those fishes found closer to shore averaged 11,000 eggs per spawning event while those offshore averaged 87,000 eggs per batch. The buoyant eggs are approximately 0.8mm in diameter, hatching 28 hours following fertilization at 23°C.

Maximum length (in inches or feet): 29.5 in

Predators: sharks and other large fish

Importance to humans: fishing/commercial

Conservation status: not endangered or vulnerable; once over-harvested but management actions have aided recovery.

Smooth butterfly ray

Scientific name: 
Gymnura micrura

Habitat: Marine; brackish; demersal. Prefers neritic waters of the continental shelf and usually found on soft bottoms. May enter brackish estuaries or hyper-saline lagoons.

Key characteristics for distinction: Broad, diamond-shaped ray with a very short tail lacking a dorsal spine. Snout protruding. Front edges of disk concave. Tail with low dorsal and ventral finfolds and 3 - 4 dark crossbars. This ray can be distinguished from the spiny butterfly ray (G. altavela) by the absence of both a tentacle like structure protruding from the inner posterior margin of the spiracle and a caudal fin spine. The absence of a tail spine and the presence of a keel on the upper surface of the tail separates G. micrura from G. hirundo.

Coloration: Upper surface gray, brown, light green or purple with round spots. Lower surface white. The tail has three to four dark crossbars.

Feeding habits/specializations: fish, shrimp, crabs, copepods, prawns, bivalves

Reproduction: Exhibits ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialized structures.

Maximum length (in inches or feet): 3-4 ft

Predators: larger fishes and marine mammals

Importance to humans: This species is caught in minor commercial fisheries and is occasionally used for food in French Guiana and possibly in other tropical localities. The wings may be taken for bait in crab or other fisheries.

Conservation status: data deficient

Fun fact: Does not possess a spine.

Southern flounder

Scientific name: 
Paralichthys lethostigma

Habitat: Marine; brackish; demersal. Found mostly over mud bottoms in estuaries and coastal waters to about 40 m depth. A cryptic species; tolerates low salinities; occurs frequently in brackish bays and estuaries, even on occasion in fresh water; this species moves to deeper water in winter, but is still easily accessible.

Key characteristics for distinction: The bodies of southern flounders are greatly compressed, with both eyes on the left side of the head. The caudal fin is separate, and the pectoral fins are rudimentary or entirely absent; none of the fins have spines. The lateral line is straight and well-developed.

Coloration: brown body with diffuse, non-ocellated spots and blotches, blind side of body white or dusky.

Feeding habits/specializations: Feeds chiefly on fishes, also on crabs and shrimps. Juveniles take mainly small bottom-living invertebrates. Predatory, ambushing prey, using camouflage to blend into surrounding habitat; foraging occurs in tidal creeks and flooded salt marsh or at marsh edges.

Reproduction: Adult southern flounder leave the bays during the fall for spawning in the Gulf of Mexico. They spawn for the first time when two years old at depths of 50 to 100 feet. The eggs are buoyant. After hatching, the larval fish swim in an upright position and the eyes are located on opposite sides of the head. As the young fish grows, the right eye begins to "migrate" to the left side of the head. When body length of about one-half inch has been attained, the eye migration is complete and the fish assumes its left-side-up position for life.

Maximum length (in inches or feet): 33 in

Predators: larger fish, seabirds, stingrays, sharks

Importance to humans: fishing/commercial

Conservation status: not evaluated (IUCN), conservation concerns: degradation and loss of tidal creek and estuary habitat; compromised water quality; potential for overfishing; lack of knowledge regarding spawning locations in some areas.

Fun fact: Both eyes in adults are on the "up" side of the head and the pigmentation of the upper side of the body can be varied to match the surrounding environment.

Spottail pinfish

Scientific name: 
Diplodus holbrooki

Habitat: Spottail pinfish are common to shallow waters (only as deep as 28m) near coasts, such as bays and harbors, though only rarely in brackish areas. They prefer flat, vegetated bottoms such as beds of sea grass. Marine; brackish; demersal.

Key characteristics for distinction: More round than the pinfish in overall shape. The name is derived from the presence of numerous spines on the front portion of the dorsal fin.

Coloration: Spottail pinfish are almost totally brown or grey in color, with a large, black spot on the distal end of the caudal peduncle. This is similar to other members of its genus, Diplodus annularis and Diplodus sargus -though D. sargus has several vertical bars that the Spottail pinfish does not.

Feeding habits/specializations: feed on a mixture of plants (such as Thalassia) and small invertebrates.

Maximum length (in inches or feet): 18 in

Predators: larger fish

Importance to humans: minor commercial fishing

Conservation status: not evaluated

Fun facts: Also called Spottail seabream

Spotted_Seatrout-DR-009

Spotted sea trout

Scientific name: 
Cynoscion nebulosus

Habitat: demersal fish that is found in brackish to marine water. It has been observed in shallow coastal and estuarine waters over sandy bottoms and seagrass to depths of 33 feet (10 m). This euryhaline fish also resides in salt marshes and tidal pools of salinities up to 75‰ (parts per thousand). Spotted seatrout associate with seagrass beds, moving to deeper pockets of water in estuaries during the cooler months. They rarely migrate far from estuaries where they are spawned.

Key characteristics for distinction: The spotted seatrout has an elongate, somewhat compressed body with a slightly elevated back. The head is long with a pointed snout and large oblique mouth. The dorsal fin is continuous or slightly separate. The fins are scaleless with the exception of 1-10 rows of small scales at dorsal and anal fin bases. The lateral line extends onto the tail which is a characteristic of all Sciaenids. The spotted seatrout has a distinctive pattern of black spots scattered along the upper body and extending into the caudal and dorsal fins.

Coloration: The body of the spotted seatrout is silvery with irregular black spots on the upper half, from the dorsal to the caudal fin. The dorsal side is dark gray with bluish reflections while the ventral side is silvery to white. The dorsal fin is dusky while other fins pale are to yellowish in color. There is a black margin on the posterior edge of the caudal fin.

Feeding habits/specializations: Plankitvores when newly hatched, move to mysids, shrimp, fish and crustaceans as they grow. Adult spotted seatrout swim in small schools with incoming tides and move into shallow areas to feed. Seatrout are ambush predators, making short lunges to grab prey with their front canine teeth prior to swallowing it whole.

Reproduction: Spawning activity, controlled primarily by temperature and salinity, peaks in the spring and late summer within the Everglades region in Florida. Along the gulf coast of Florida, spawning occurs from late March to September with a peak during June through August. Unimodal or bimodal spawning activity peaks vary temporally and geographically. Spawning occurs during the nighttime hours and is signified by the croaking sounds made by males occurring one to two hours prior to sunset. Shallow bays and lagoons as well as deeper channels and depressions close in proximity to grass flats are utilized as spawning locations by the spotted seatrout. Spawning behavior includes a lot of jumping as well as side to side body contact among individuals.

Maximum length (in inches or feet): 39 in

Predators: gar, striped bass, atlantic croaker, barracuda; seabirds, porpoises and sharks

Importance to humans: fishing

Conservation status: not evaluated

Fun fact: Landed seatrout often have "spaghetti" worms embedded in the flesh.

Rockfish-DR-001

Striped bass

Scientific name: 
Morone saxatilis

Habitat: Marine; freshwater; brackish; demersal; anadromous. Inhabit coastal waters and are commonly found in bays but may enter rivers in the spring to spawn. Some populations are landlocked.

Key characteristics for distinction: Dark, forked tail fin. Deep notch in dorsal fin. First part of dorsal fin has several spines. Three spines on anal fin.

Coloration: streamlined, silvery body marked with longitudinal dark stripes running from behind the gills to the base of the tail.

Feeding habits/specializations: Voracious and opportunistic feeder. Larvae feed on zooplankton; juveniles take in small shrimps and other crustaceans, annelid worms, and insects; adults feed on a wide variety of fishes (alewives, herring, smelt, eels, flounders, mummichogs, rock gunnels, sand lance, silver hake and silversides) and invertebrates (squid, crabs, sea worms and amphipods), mainly crustaceans. Feeding ceases shortly before spawning.

Reproduction: Striped bass spawn in fresh water, and although they have been successfully adapted to freshwater habitat, they naturally spend their adult lives in saltwater. Spawning occurs from April to early June in the Chesapeake Bay's tidal tributaries. During spawning season, several males court a single female, who lays her eggs in fresh or brackish water near the shore. After spawning, adults swim downstream to the Bay. Some continue on to the ocean. Eggs hatch in two to three days, after which larvae move slowly downstream.

Maximum length (in inches or feet): 6 ft

Predators: humans (fishing), other larger fish, sharks

Importance to humans: sport fishing

Conservation status: not evaluated

Fun fact: State Fish of Maryland, Rhode Island, and South Carolina.

Supraocular tentacles absent or much smaller than eyes. 5 to 7 large dark blotches on back and sides, with many, approximately parallel to obliquely intersecting dark lines distributed over light background color. Strong parrot-like beak.

Coloration: yellowish-green in color with dark wavy stripes. Large dark spots at base of dorsal fin and above and behind pectoral fins.

Feeding habits/specializations: invertebrates like barnacles and hermit crabs; uses powerful beak-like jaws to crush and consume prey; sometimes eats prey whole.

Reproduction: Believed to spawn offshore at night; little is known.

Maximum length (in inches or feet): 11 in

Predators: Fends off predators by puffing its body into a spiny ball.

Importance to humans: not commercial fished or sort after; often killed as by-catch in gill nets.

Conservation status: least concern

Fun fact: Burrfish are not very good swimmers. They move by squirting water out of their gill openings, which jets the fish forward.

Striped Mullet

Stripped mullet

Scientific name: 
Mugil cephalus

Habitat: Marine; freshwater; brackish; benthopelagic; catadromous. Coastal species that often enters estuaries and freshwater environments. Adult mullet have been found in waters ranging from 0 ppt to 75 ppt salinity while juveniles can only tolerate such wide salinity ranges after they reach lengths of 1.6-2.8 inches (4-7 cm). Adults form huge schools near the surface over sandy or muddy bottoms and dense vegetation. There is a large dark blotch at the base of the pectoral fin. The pigmentation in the iris is dispersed and brown, a character that also helps to distinguish it from Mugil curema.

Key characteristics for distinction: The body of the striped mullet is subcylindrical and anteriorly compressed. It has a small, terminal mouth with inconspicuous teeth and a blunt nose. The lips are thin, with a bump at the tip of the lower lip. The adipose eyelid is prominent with only a narrow slit over the pupil. The body is elongate and the head is a slightly wider than deep. Pectoral fins are short, not reaching the first dorsal fin. The origin of the second dorsal fin is posterior to the origin of the anal fin. The lateral line is not visible.

Coloration: grayish olive to grayish brown, with olive-green or bluish tints and sides fading to silvery white towards the belly. Dark longitudinal lines, formed by dark spots at the center of each scale on the upper half of the body, run the length of the body.

Feeding habits/specializations: diurnal feeders, consuming mainly zooplankton, dead plant matter, and detritus. Mullet have thick-walled gizzard-like segments in their stomach along with a long gastrointestinal tract that enables them to feed on detritus.

Reproduction: spawn in saltwater yet spend most of their lives in freshwater. During the autumn and winter months, adult mullet migrate far offshore in large aggregations to spawn. Estimated fecundity of the striped mullet is 0.5 to 2.0 million eggs per female, depending upon the size of the individual. Hatching occurs about 48 hours after fertilization.

Maximum length (in inches or feet): 47.2 in

Predators: fishes, birds, marine mammals.

Importance to humans: fishing/bait. Also used in Chinese medicinal practices. Important commercial fish.

Conservation status: least concern

Fun fact: Striped mullet leap out of the water frequently. This may be because the fish spend much time in areas that are low in dissolved oxygen. Leaping out of the water clears their gills and exposes them to higher levels of oxygen.

014-Summer_Flounder copy

Summer flounder

Scientific name: 
Paralichthys dentatus

Habitat: Marine; demersal; oceanodromous. Adults usually prefer hard sandy substrate where they can burrow; can exploit a broad range of lower and mid-estuary habitats including salt marsh creeks and seagrass beds, which usually have muddy or silty substrates, as well as sand flats. Occur in bays, lagoons and shallow coastal waters.

Key characteristics for distinction: long dorsal fin stretches from head to tail, flat rounded body, slightly pointed tail fin

Coloration: brownish on top and whitish on bottom, various large spots on the top side of body; camouflages itself

Feeding habits/specializations: The teeth are quite sharp and well developed on both upper and lower jaws. Adults are highly predatory and considered mostly piscivorous, often lying buried with only their head exposed to ambush prey which includes sand lance, menhaden, Atlantic silverside, mummichog killifish, small bluefish, porgies, squid, shrimp, and crabs. While primarily considered a bottom fish, they are rapid swimmers over short distances and can become very aggressive, feeding actively at mid-depths, even chasing prey to the surface.

Reproduction: Spawns in autumn and mid-winter in coastal ocean waters. After hatching, larvae have one eye on each side of the head. The right eye gradually travels to the left side of the head to a position next to the left eye.

Maximum length (in inches or feet): 3 ft

Predators: conceals itself from predators by burying itself in bottom sediments and changing colors to blend in with its surroundings.

Importance to humans: fishing/commercial

Conservation status: least concern

Fun fact: At hatching, one eye is located on each side of the brain. As it grows from larval to juvenile stage, one eye migrates to the other side of the body as a process of metamorphosis.

Tarpon

Scientific name: 
Megalops atlanticus

Habitat: Marine; freshwater; brackish; reef-associated; amphidromous. Primarily found in coastal waters, bays, estuaries, and mangrove-lined lagoons within tropical, subtropical, and temperate climates (45° N-30° S). The normal habitat depth extends to 98 feet (30 m). Although a marine fish, tarpon can tolerate euryhaline environments (0-47 parts per thousand) and often enter river mouths and bays and travel upstream into fresh water. In addition, tarpon can also tolerate oxygen-poor environments due to a modified air bladder that allows them to inhale atmospheric oxygen.

Key characteristics for distinction: Externally, the almost vertical, silvery sides made up of large scales are the most distinctive feature of the tarpon. The tarpon has a superior mouth with the lower mandible extending far beyond the gape. The fins contain no spines, but are all composed of softrays. The dorsal fin appears high anteriorly and contains 13-15 softrays with the last ray greatly elongated into a heavy filament. The caudal is deeply forked, and the lobes appear equal in length. The anterior portion of the anal fin is deep and triangular. The fin has 22-25 softrays, with the last ray again elongated as in the dorsal fin, but shorter and only present in adults. The tarpon has large pelvic fins, and long pectoral fins containing 13-14 softrays. Perhaps the most unique internal feature of the tarpon is the modified swim bladder. This swim bladder contains spongy alveolar tissue and has a duct leading to the esophagus that the tarpon may fill directly with air gulped from the surface. This feature allows the tarpon to take oxygen directly from the atmosphere and increases its tolerance of oxygen-poor waters. In fact, studies have shown that tarpon must have access to atmospheric oxygen in order to survive, and that juvenile tarpon are obligatory air-breathers. Adults living in oxygen-rich waters still roll and gulp air, probably as an imitative pattern based on visual perception of other tarpon.

Coloration: The synonym "silver king" refers to the predominant bright silver color along the sides and belly of the tarpon. Dorsally, tarpon usually appear dark blue to greenish-black. However, the color may appear brownish or brassy for individuals inhabiting inland waters. The dorsal and caudal fins have dusky margins and often appear dark.

Feeding habits/specializations: carnivorous, mid-water prey: fish, shrimp, crabs. Feeding day and night; usually swallow prey whole.

Reproduction: The fish typically spawn in May, June, and July, though evidence exists that suggests they spawn year-round. They make extensive migrations to offshore spawning areas where currents then move the larvae to inshore nurseries.

Maximum length (in inches or feet): 8 ft

Predators: fishes, birds, sharks, porpoises.

Importance to humans: Commercial sale of Tarpon prohibited in Florida. Special tags required to catch Tarpon.

Conservation status: Vulnerable.

Fun fact: Also called the silver king; jumps into the air.

Key characteristics for distinction: Blunt head with greenish eyes and thick lips. Stout, rounded body.

Coloration: Varies in color from brown to grayish or black with irregular bars or blotches on the sides. Females and small males have a black chin. Some larger males have a white chin. Thick, squared tail fin.

Feeding habits/specializations: Feeds mainly on mussels, gastropods, other mollusks and crustaceans.

Reproduction: Spawning was noted in June-July in Canadian waters, but appears more protracted (April-July) in coastal waters of Virginia, USA. Spawns from late April-early August in the lower Bay and offshore. The female lays about 200,000 eggs. After hatching, bright green tautog larvae drift for about three weeks before settling in shallow bay grass beds. In about 3 years, tautogs become sexually mature and lose their bright green coloring

Maximum length (in inches or feet): 3 ft

Predators: larger fish

Importance to humans: fishing managed closely due to conservation status.

Conservation status: Vulnerable; slow reproduction and growth.

Fun fact: When they are not feeding, tautogs are known to find a hole and lie motionless on their side. The fish are so inactive at night that sport divers have been able to catch them by hand.

Weakfish-DR-008

Weakfish

Scientific name: 
Cynoscion regalis

Habitat: Marine; brackish; demersal; oceanodromous. Occurs usually in shallow coastal waters over sand and sandy mud bottoms. Juveniles are euryhaline. During summer the fish move to their nursery and feeding grounds in river estuaries. Lives in schools.

Key characteristics for distinction: Sleek body, deep notch in dorsal fin, squared tail fin, two large canine teeth in upper jaw.

Coloration: Dark, olive green back with iridescent blue, copper or green on sides; silvery white belly; small, dark spots on back that form irregular diagonal lines.

Feeding habits/specializations: Feeds mainly on crustaceans and fishes. Once it sees its prey, will slowly move toward it then quickly lunge with open jaws.

Reproduction: Oviparous, with high fecundity. Spawns April-August, females produce more eggs as they get larger.

Maximum length (in inches or feet): 3 ft

Predators: other predatory fish like bluefish and striped bass, sea lampreys, dusky sharks.

Importance to humans: fishing/commercial

Conservation status: not evaluated

Fun fact: Makes drumming or purring sound. Name Weakfish comes from fragile mouth which tears easily when hooked.

White_Perch-DR-003

White perch

Scientific name: 
Morone americana

Habitat: Marine; freshwater; brackish; demersal; anadromous. Occurs in fresh, brackish and coastal waters. Primarily found in brackish water but common in pools and other quiet water areas of medium to large rivers, usually over mud.

Key characteristics for distinction: Highly domed back, slightly projecting lower jaw, mildly forked tail, deep notch in dorsal fin – first part of dorsal fin as several spines. Three anal spines.

Coloration: Silvery, greenish-gray body; gray or blackish back, whitish belly. Faint lines on sides.

Feeding habits/specializations: small fish, insects, detritus and fish eggs/larvae

Reproduction: Semi-anadromous because it does not travel all the way from ocean to spawning grounds in freshwater rivers; begins spawning runs when water temperatures increase in late March.

Maximum length (in inches or feet): 19.5 in

Predators: bluefish, weakfish, striped bass; humans

Importance to humans: fishing/commercial minor

Conservation status: least concern

Fun fact: A close relative of striped bass.

013-Winter_Flounder copy

Winter flounder

Scientific name: 
Pleuronectes americanus

Habitat: Marine; demersal; oceanodromous. Adults inhabit soft muddy to moderately hard bottoms.

Key characteristics for distinction: Flat elliptical body, small head and mouth located on right side of body. Distinct pectoral fin present just behind gill opening. Separate small pelvic fin present on belly.

Coloration: Color pattern of “dark side” can change depending on the color and pattern of surrounding substrate ranging from reddish brown to olive green to almost black. Underside is white

Feeding habits/specializations: Feed predominantly in daytime on organisms living in, on or near the bottom; shrimps, amphipods, crabs, sea urchins and snails. Can camouflage itself against passing prey.

Reproduction: Batch spawners. Occurs in nearshore and estuarine waters from late winter to early spring.

Maximum length (in inches or feet): 25 in

Predators: Can hide from predators using camouflage. Common predators – sharks, oyster toadfish, summer flounder, striped bass, monkfish and spiny dogfish.

Importance to humans: commercial/fishing/experimental

Conservation status: not evaluated

Fun fact: Differ from summer flounder based on where the location of the eyes/head. Can use its body shape to dig into the substrate to cover itself and hide.

White Grunt


White grunt

Scientific name: 
Haemulon plumieri


Habitat: Marine; reef-associated; depth range 3 - 40 m. Found in dense aggregations during the day on patch reefs, around coral formations, or on sandy bottoms.

Key characteristics for distinction: The body is moderately elongate, with an elevated and compressed back. The head is long with a sharp snout. Dorsal and anal fins of the white grunt are completely covered with scales. The caudal fin is forked and the pectoral fin long and falcate. Scales above the lateral line larger than scales located below the lateral line.

Coloration: Silvery white to cream-colored, the head is bronze to yellow dorsally while the ventral side of the head and belly is white. There is a series of dark blue stripes on the head, margined with yellow-bronze running back into the body. Each scale's margin is bronze and the posterior edge is often gray. Scale rows above the lateral line are larger than those below the lateral line. The spinous dorsal fin is chalky to yellowish-white, the soft dorsal, soft anal, and caudal fins are brownish gray. The pelvic fins are chalky, while the pectoral fins range from light yellow to chalky in color. A black blotch is located on the preopercle and the inside of the mouth is red. The color of this fish is changeable, with the fish appearing in a shade matching the immediate surroundings.

Feeding habits/specializations: The white grunt feeds nocturnally, migrating off the reefs to open sandy, muddy, or grassy areas. Typically moving off the reef shortly after sunset and returning to the reef just prior to sunrise, large white grunts are the first to leave and last the return. This fish is considered a generalized carnivore, scavenging benthic crustaceans, mollusks, echinoderms, and small fishes. Grunts have also been observed to feed on material attached to pilings near offshore platforms. The small juvenile grunts pick plankton, primarily copepods, from the water column during daylight hours.

Reproduction: Peak spawning occurs during much of the year with peaks occurring during May and June off Florida, August and September off Puerto Rico and in March and April off Jamaica. Spawns offshore, over hard bottoms or reefs.

Maximum length (in inches or feet): 21 in

Predators: Snappers, groupers, lizardfishes, spanish mackerel, sharks and other large piscivores

Importance to humans: Reports of ciguatera poisoning. Fishing/commercial minor

Conservation status: not evaluated

Fun fact: Frequently exhibits a territorial 'kissing' display in which two contenders push each other on the lips with their mouths wide open.
