Common Name: Bluefish
Latin Name: Pomatomus saltatrix
Size/weight: Rarely seen larger than 20 pounds and 40 inches long.
Range: Western Atlantic populations range from Canada in the north to Florida and the Gulf of Mexico in the south (depending on season).
Habitat: Adults inhabit coastal waters and are, at times, found in estuaries, harbors and off sandy beaches.
Diet: The bluefish’s diet includes squid, crabs, butterfish, menhaden, shad, herring, hake and smaller bluefish. Bluefish are known as very aggressive fish and will often leave partially eaten or maimed prey behind.
Predators: Sharks, tuna, striped bass, swordfish and humans.
Description: Actually more green than blue, bluefish have strong, streamlined bodies and sharp, conical teeth.
Conservation Note: Many fisheries managers believe that bluefish are being over-fished; populations may be on the brink of decline. However, Seafood Watch still lists bluefish as a Good Alternative, but consumers should limit consumption due to concerns about mercury or other contaminants.
Common Name: Atlantic cod
Latin Name: Gadus morhua
Size/weight: Up to 51 inches long and 77 pounds.
Range: Both sides of the North Atlantic, on our side from Greenland to Cape Hatteras.
Habitat: Near the bottom of the water column in areas range from near shore to the edge of the continental shelf.
Diet: Cod are omnivorous, feeding on a wide variety of fish and invertebrates.
Predators: Humans, larger fish.
Description: Greenish, brown or grey dorsally, lighter shading ventrally. Prominent barbel on chin. Spots on back and sides. Three dorsal fins and two anal fins.
Conservation Note: Although fishing for cod was once a dominant part of the New England economy, in recent decades overfishing has severely depleted cod stocks. Thus, Seafood Watch lists Atlantic cod as a seafood to Avoid, except for cod obtained through hook-and-line fishing in the Gulf of Maine.
Common Name: Cownose ray
Latin Name: Rhinoptera bonasus
Size/weight: Up to 45 inches wide (wing tip to wing tip) and 50 pounds.
Range: Massachusetts to Brazil
Habitat: Sandy, soft bottom areas.
Diet: Clams, oysters and bottom-dwelling invertebrates.
Predators: Sharks are the cownose ray’s main predators. Humans; disc-shaped cutouts of ray wings are sometimes passed off as scallop. Cownose rays are also sometimes cut up as bait for other fish.
Description: Grey on top and white on bottom, cownose rays have broad wings, a long thin tail, and a notched head that some say resembles a cow’s muzzle (hence the name “cownose” ray). Sharp, venomous spine (stinger) at the base of the tail. A relative of sharks and skates, the cownose ray’s skeleton is made up of cartilage, not bones.
Conservation Note: Not listed as endangered or vulnerable.
Common Name: American eel
Latin Name: Anguilla rostrata
Size/weight: Females average 2 to 3 feet but may grow to 5 to 6 feet long. Males are generally half as big.
Range: American eels range from Greenland to South America, occurring in all major streams along the Atlantic coastline. The females migrate far inland, and have been documented in nearly all states east of the Rocky Mountains. This is possible because eels are able to live out of water for short periods of time. Their ability to slither up a moist slope allows them to circumnavigate major obstructions (e.g. dams and waterfalls) along their routes.
Habitat: Varies by life stage. See “Description” below.
Diet: insects, smaller fish, fish eggs, crustaceans, worms, frogs.
Predators: At sea: fish, birds. In inland waters: fish, turtles, birds, raccoons.
Description: This is a fish – and eels are fish, by the way – that lives a life of several amazing metamorphisms that take it from sea water to fresh water and then back out to the salty ocean again. (That’s something few fish can do.)
An eel’s life stages are:
• “leaf fish” – These larvae look sort of like a clear flat willow leaf. Hatching in the Atlantic’s Sargasso Sea (SE of Bermuda), they ride the Gulf Stream currents for about a year.
• “glass eel” – Nearing the East Coast, leaf fish morph into the familiar eel shape. Tiny glass eels are still transparent but can now actively swim toward land.
• “elver” – Entering estuaries, they take on a brownish pigment.
• “yellow eel” – As elvers feed and grow, they turn olive-green with a yellow underside. They’ll stay in this adult stage for 5 to 20 years. Females swim upstream into fresh water and may even wriggle across land to ponds and lakes. Males tend to stay in more brackish waters.
• “silver eel” – In the fall, yellow eels that are ready to reproduce will stop eating, take on a silvery hue and their digestive systems shrink away to make room for new reproductive organs. Fueled only by their fat reserves, they swim back out to the Sargasso Sea to mate, lay eggs and die.
Conservation Note: Eel “landings” peaked in the late 1970s and early 1980s when record quantities of eels were caught and shipped to Asia, where folks have a taste for juvenile eels called elvers. But we caught too many eels too quickly. The number of eels harvested since then has dropped dramatically.
According to estimates from the International Council for Exploration of the Seas (ICES), the “recruitment level” (that is, the baby eels produced each year) is only 1 percent of what it was before the 1980s. Populations may be at record-low levels. In 2000, the Atlantic States Marine Fisheries Commission (ASMFC) issued an eel management plan. As eel “landings” continued to decline, the commission approved further protections in 2004. The U.S. Fish & Wildlife Service is reviewing whether eels need protection as a threatened or endangered species.
Besides overfishing, eel issues identified by the ASMFC include:
• dams have blocked eels from their migrations up rivers and streams.
• climate change may raise sea levels, which could affect the Sargasso Sea, a huge area south of Bermuda that is the American eel’s only mating spot/hatchery.
• climate change also could alter the Gulf Stream, hindering the migration of glass eels toward land.
• pollutants collect in eels’ fat reserves. That’s bad news for both the eels and anyone who eats them.
Although it may be hard to rally public support around an animal that is slimy and snake-like, things are being done to help eels. It’s now illegal to ship eels into or out of Europe. In the U.S., recent changes in size regulations have eliminated the elvers fishery in all states except Maine and Florida. And in Connecticut, the U.S. Fish & Wildlife Service, the Nature Conservancy, municipal conservation groups and the Aquarion Water Co., which supplies water to 39 cities and towns, all have been working on ways to help eels get around dams.
See them in their own exhibit in the Rivers to the Sound watershed gallery.
Common Name: Atlantic marsh fiddler crab
Latin Name: (Uca pugnax)
Size/weight: A small crab whose body (or carapace) is about 1 inch across. Males are slightly larger than females and have a blue spot on the top center.
Range: Cape Cod down to northern Florida. This is the most common species of fiddler crab on the U.S. East Coast.
Habitat: in the intertidal mud of salt marshes. The crabs dig burrows, which they use for resting, mating, safety and hibernating. (They are known to roll up a ball of mud to plug their burrow hole at high tide.)
Diet: They eat the mud too – well, they eat the tiny bits of fungus, algae, microbes, decaying plant & animal matter, and other organisms in the mud. What they don’t digest is deposited back as little mud balls.
Predators: Herons, gulls and other birds; raccoons; blue crabs; and other marsh predators.
Description: Olive-brown in color. Dark banded walking legs. Slender eye stalks. Fiddler crabs are easily identified by the males, which have one ridiculously large yellowish claw – an adaptation that developed to help them attract females. A bigger claw gets the girl. The large claw, called the chela, can be either the male’s left or right. Also, males have a blue spot on the top center of their carapace.
Note: Because all their digging helps to aerate the marsh, fiddler crabs are great for a marsh’s health.
Why are they called fiddler crabs? When a male feeds, the back-and-forth movement of its small claw (from the ground to its mouth) near its large claw resembles the motion of someone moving a bow across a fiddle.
Fiddler crabs are very skittish and retreat quickly to their marsh burrows. If you don’t want to go marsh-muckin’ in search of fiddler crabs, you can find them in The Maritime Aquarium's Salt Marsh Gallery.
Common Name: Gray Tree Frog
Latin Name: Hyla veriscolor
Size/weight: Small (1.5 to 2 inches)
Range: Most of the eastern half of the U.S., and north into Canada.
Habitat: Woods near swamps, ponds and rivers.
Diet: They are nocturnal hunters of flies, moths, caterpillars, beetles, ants, spiders, crickets and other invertebrates.
Predators: Birds, snakes, other larger frogs. (Fish eat the tadpoles.)
Description: Usually blotchy gray but also shades of brown and green. They can change their color to match their surroundings. Few frogs can do this. Whatever color a gray tree frog is at the moment, its inner thighs will always be yellowish-orange. Backs are warty in appearance, although of course those aren't warts.Conservation Note: Not considered to be threatened or endangered. However, habitat destruction and human pollutants are contributing to the overall decline of amphibians.
Common Name: Flatclaw hermit Crab
Latin Name: Pagurus pollicaris and p. longicarpus
Size/weight: About 1⁄2 inch long & wide for P. longicarpus, one inch or more for P. pollicaris
Range: Gulf of Maine to Gulf of Mexico
Habitat: Sandy and other bottom habitats in depths up to 150 feet.
Diet: Food (detritus and algae) scavenged off the bottom and within the sand and mud.
Description: The hermit crab is famous for borrowing the shells or snails or other animals as their own home. Inside the shell, their hermit crab’s body is long, soft and roughly cylindrical with small appendages, antennae and prominent eye stalks.
Conservation Note: Not listed as endangered or vulnerable.
Common Name: Horseshoe crab
Latin Name: Limulus polyphemus
Size/weight: Up to 24 inches long and 12 inches wide; 3 or 4 pounds.
Range: Found from Maine to the Yucatan (Mexico).
Habitat: Estuaries to continental shelf
Diet: Worms, bivalves and other bottom dwelling creatures.
Predators: Migratory shorebirds, humans (fishing bait).
Description: The horseshoe crab’s name is somewhat misleading. Although it is shaped like a horseshoe, it’s no crab. The horseshoe crab is an arachnid, a class of arthropods that also includes scorpions, spiders, mites and ticks. With two main eyes, two simple (light sensing only) eyes and a mouth on the bottom, the horseshoe crab is well suited to life on the bottom. A brownish segmented shell offers protection and a pointed tail helps the animal right itself; it’s not used for attacking or even self-defense.
Conservation Note: After surviving on Earth for 300 million years, horseshoe crab numbers are declining. A local study, in which The Maritime Aquarium participates, is looking to find out the health and habits of the horseshoe crab population in Long Island Sound.
Common Name: Lion’s mane jelly
Latin Name: Cyanea capillata
Size/weight: locally, up to 12 inches in diameter. (But in the Arctic have been measured 7 feet across with tentacles 100 feet long – that’s longer than a blue whale! Thus lion’s manes are the largest known species of jelly ... and one of the world’s largest animals.)
Range: northern Pacific and Atlantic oceans (including Long Island Sound, where they often are seen in July & August); Arctic Ocean.
Habitat: Floats near surface in offshore waters.
Diet: zooplankton, fish eggs, small shrimp, occasionally other developing jellies.
Predators: Sea turtles, sunfish, some sea birds.
Description: Translucent with an interior body (or bell) coloring that varies with size: smaller individuals skew to orange, while larger specimen reach a vivid crimson. Thick tangle of oral arms under the bell, within long thin tentacles. Their stings are painful but generally not fatal. Like all jellies, they cannot swim against currents and instead are carried by currents (thus, they are a type of plankton). For that reason, and for the fact that they have no eyes, lion’s manes (and all jellies) do not pursue and intentionally sting swimmers.
Conservation Note: An abundant, non-threatened species.
Common Name: American or Northern lobster
Latin Name: Homarus americanus
Size/weight: Extreme cases: up to 40 pounds and 3 feet long
Range: Labrador to Cape Hatteras; most common from Nova Scotia to New York
Habitat: Crevices or burrows in rocky reefs and muddy bottom habitats
Diet: Fish, mollusks and other crustaceans scavenged on or near the bottom.
Predators: Sharks, cod, wolfish, goosefish, striped bass, and people with bowls of melted butter.
Description: Most common coloration is greenish brown, but genetic and other factors can produce lobsters of a wide variety of colors. Two large front claws, one for grabbing and crushing, the other for ripping and tearing. Eight legs extend from the carapace, segmented abdomen and wide tail.
Conservation Note: Lobster populations have not rebounded since a devastating die-off in Long Island Sound in 1999. Warming waters due to climate change threaten the lobster's long-term prospects in the Sound.
Common Name: Moon jelly
Latin Name: Aurelia aurita
Size/weight: Up to 16 inches in diameter
Range: Arctic to Florida or Mexican; in the Pacific from Alaska to southern California
Habitat: Floats near surface in offshore waters.
Diet: Small plankton, fish eggs, occasionally other developing jellies.
Predators: Sea turtles, sunfish.
Description: Translucent; recognizable for the four horseshoe-shaped organs in their center and a single row of short, hair-like tentacles around the bell. Since they’re not really fish, it is more proper now to call them “jellies,” instead of jellyfish. Moon jellies are only mildly toxic to most people; the sting is likely to cause nothing more than a persistent, itchy rash. But some folks may have more severe reactions.
Conservation Note: An abundant, non-threatened species.
Common Name: Eastern oyster (sometimes called American or Virginia oyster)
Latin Name: Crassostrea virginica
Description: A prolific bivalve mollusk with thick irregular grayish-white shells with concentric ridges. The left (or bottom) shell is cupped with a purple muscle scar inside. The right (or top) shell is smaller and flatter.
Size/weight: Shells generally are 3 to 5 inches long
Range: Eastern North America, from the Gulf of St. Lawrence to the Gulf of Mexico
Habitat: Estuarine or salty water, in intertidal and subtidal zones. They can grow in great beds or reefs, with new immature animals "setting" on old empty shells. Oyster reefs provide bottom habitat for other marine invertebrates and fish species.
Diet: Oysters are filter-feeders. They open their shell & pump in water, which draws planktonic food in as well. (Oysters filter so much water that a large population of oysters can effectively help keep a body of water clean.)
Predators: Sea stars, crabs, oyster drills and other snails, some fish, humans.
Note: The Eastern oyster was designated as Connecticut's state shellfish in 1989.
Norwalk and the Eastern oyster go way back. The city’s Oyster Shell Park, which extends up the pathway along the Norwalk River north of the Aquarium, was once the site of a native American oyster midden – a place where the local tribe piled up its empty oyster shells.
The waters of Long Island Sound just off of Norwalk are a perfect place for oysters, offering just the right temperatures, salinities, substrate and currents, plus a lack of severe storms. Oysters grow wild, but – even by the early 1700s – were being farmed as well. Oystering boomed through the 1800s, serving as a huge economic driver for Connecticut’s shoreline communities. And these just weren’t any oysters. The oystermen were farming a particular variety with a deliciously distinct taste they called Bluepoints. They could barely keep up with the demand.
(In The Maritime Aquarium at our Toy Boat-Making workshop, check out a 1937 Works Progress Administration – or WPA – mural of an oyster-shucking operation.)
Oystering in the Sound hit hard times in the early half of the 20th century (mainly from pollution) and in the late 1990s (from parasites). But the industry is thriving again today, with two of Connecticut’s biggest companies based on either side of the Norwalk harbor. Oyster connoisseurs still rank Bluepoints among the best in the world. The legendary Oyster Bar restaurant in Grand Central Station reportedly serves 1,000 Norwalk oysters a day – one-fourth of them Bluepoints.
See oyster shells in one of the salt-marsh gallery exhibits, and touch them at our Intertidal Touch Tank.
Common Name: North American river otter
Latin Name: Lontra canadensis
Size/weight: Adult size is about 2.5 – 5 feet long (with tail) and 10 – 30 pounds.
Range: Throughout North America (Alaska, Canada and the lower 48 United States).
Habitat: River otters can be found in or near fresh water (lakes, streams, marshes, etc…) and in brackish waters. They build their dens (or take over abandoned dens of other animals) in riverbanks or in a natural hollow near the water.
Diet: North American river otters find most of their food in the water; amphibians, fish, turtles, crayfish, crabs and other invertebrates are favorites. Birds, eggs, aquatic plants, and small land mammals are sometimes on a river otter’s menu.
Predators: Bobcats, coyotes, birds of prey, dogs. Hunting.
Description: With their long, streamlined bodies and thick, tapered tails North American River otters are well suited to a life around the water. (Although they run with a distinctive "humpbacked" gait, they can run even faster than they can swim.) Otter fur is thick and dark brown, lighter on the underside. Long, sensitive whiskers help them find food under water.
Conservation Note: Once heavily hunted for their fur, North American river otter populations continue to rebound. In Connecticut, the population is large and stable enough to have a legal trapping season. Threats come from development and pollution, as otters prefer quiet areas with clean water.
Common Name: Atlantic salmon (East Coast)
Latin Name: Salmo salar
Size/weight: Up to 4.5 feet and 80 pounds
Range: Arctic Circle to Delaware River, also some landlocked populations.
Habitat: Coastal waters, as well as freshwater rivers and lakes.
Diet: Herring, capelin, sand eels and large plankton.
Predators: Seals, sharks, pollack, tuna, skates, halibut, cod, striped bass, bluefish; humans.
Description: Long body, brownish above with silvery sides featuring black spots. Lower jaw hooked up in breeding males, who may also feature red areas on their sides. Spawns in fresh water, but spends most of its life at sea.
Conservation Note: Listed on the U.S. Endangered Species List due to overfishing, disease, interaction with hatchery populations, and dammed and polluted spawning rivers. Seafood Watch lists farmed Atlantic salmon as a seafood to Avoid, and says Alaskan wild salmon is the Best Choice.
Common Name: Lined seahorse
Latin Name: Hippocampus erectus
Size/weight: Up to 5 inches
Range: Nova Scotia to Argentina; Bermuda and Gulf of Mexico
Habitat: Found in shallow waters among grasses
Diet: Brine shrimp and other live zooplankton.
Predators: Crabs, skates and rays; humans.
Description: Body is upright with a head (shaped liked a horse head) perpendicular to body. Dorsal fin is fan shaped. Tail is prehensile and lacks a caudal fin. Color varies from light brown to almost black and can change depending on the background. It is the male of the species that gives birth.
Conservation Note: Considered a vulnerable species due to pollution, habitat destruction and overfishing (with a high demand from the Asian market for use in traditional medicines, and as a desirable fish for home aquariums).
Common Name: Harbor seal
Latin Name: Phoca vitulina
Size/weight: Between 5 and 6 feet long; 175 – 225 pounds. Males are sometimes larger.
Range: Harbor seals can be found throughout the northern Atlantic, along both coasts.
Habitat: Harbor seals “haul out” on offshore rocks and sand bars in the Sound that are exposed during low tide. The term “haul out” refers both to the location like a rock where the seal is resting (the “haul out” site) and to the action of a seal climbing out of the water onto land (to “haul out”).
Diet: Varies regionally, but generally consists of fish, crabs, lobster and squid.
Predators: Main predators include killer whales and sharks. Large eagles, coyotes and gulls have been known to prey on seal pups.
Description: Harbor seals range in color from brown, tan, light grey and silver with dark spots. Their thick short coat is made of coarse guard hairs and finer, but denser under hairs.
Conservation Note: Since the passage of the Marine Mammal Protection Act in 1972, harbor seal populations have been rebounding from depletion by hunting and other threats. The generally improving health of Long Island Sound also seems to be a factor in the seals’ return.
Common Name: Forbes sea star
Latin Name: Asterias forbesi
Size/weight: Five or so inches in diameter
Range: Gulf of Maine to Texas
Habitat: Low tide line to depths of 160 feet; rock, gravel or sandy bottom.
Diet: Clams, scallops and oysters. Stomach is everted into the prey animal, where it digests the tissue.
Predators: Spider crabs and, occasionally, lobsters.
Description: Five arms radiating from a central core with an eye at the end of each arm, thousands of tiny tube feet, and a mouth on bottom. Tough, almost spiny skin; color brownish red or orange. The sea star is able to regenerate severed arms.
Conservation Note: Not listed as threatened or endangered.
Common Name: Green sea turtle
Latin Name: Chelonia mydas
Size/weight: Green turtles are the largest of all the hard-shelled sea turtles. They can grow up to 4 feet long and 400+ pounds.
Range: Tropical and sub-tropical waters around the world. In the western Atlantic, as far north as Massachusetts (including Long Island Sound) in summers. Nesting occurs in over 80 countries.
Habitat: Primarily coastal areas, where they’ll find the plants they eat.
Diet: Adult green turtles are unique among sea turtles in that they eat only plants; they are herbivorous, feeding primarily on seagrasses and algae. This diet is thought to give them greenish-colored fat, from which they take their name.
Predators: Newly hatched turtles are vulnerable to everything from raccoons and gulls to crabs and large fish. Some sharks may prey on adult sea turtles.
Description: Heart-shaped shell, small head and single-clawed flippers. Color will vary. The top shell (or carapace) is smooth with shades of black, gray, green, brown, and yellow; the bottom shell (or plastron) is yellowish white. Oxygen reserves allow them to dive without surfacing for 30 minutes and even sleep underwater for more than two hours without breathing.
Conservation Note: Breeding populations in Florida & on Mexico’s Pacific coast are endangered. All other populations are threatened. Despite conservation agreements around the globe, the main threats remain the over-harvesting of eggs and adults, and from accidental mortality in the nets and long-lines of fishing and shrimping fleets.Artificial lights confuse the ocean-bound babies, causing them to lose their way. Real estate development eliminates their nesting habitat. And cast-off plastic bags, fishing line and other trash can suffocate, strangle or otherwise harm the animals.
Common Name: Loggerhead sea turtle
Latin Name: Caretta caretta
Size/weight: Up to 38 inches long and 400 pounds when fully grown.
Range: Found in warmer waters in the Atlantic, Indian and Pacific Oceans. In the western Atlantic, loggerheads can be found from Newfoundland to Argentina. Juvenile loggerheads sometimes visit Long Island Sound during the summer.
Habitat: Loggerheads can be found throughout their range anywhere from shoreline lagoons, bays and river mouths to thousands of miles out to sea. Nests are typically dug on sandy beaches between the high tide line and the beginning of dunes or vegetation.
Diet: Mollusks, crustaceans, fish, etc.
Predators: Loggerheads are at greatest risk from a variety of human and animal predators who disturb the nest sites, eating and taking eggs. Many hatchlings are also eaten as they try to make their way from the nest into the water. Seagoing adults are often trapped and drown in long-line fishing nets.
Description: Loggerheads are so named for their large, seemingly over-sized head. They have a sharp beak, a large reddish-brown carapace and yellowish skin. Unlike land turtles, a sea turtle can’t tuck its head or flippers into its shell.
Conservation Note: Although loggerhead sea turtles are the most abundant sea turtle in U.S. waters, their population is still low enough to list them as “threatened” on the Endangered Species List. Newer “turtle exclusion devices” on fishing nets may be reducing turtle deaths.
Common Name: Sand tiger shark
Latin Name: Carcharias taurus
Size/weight: Up to 10 or 11 feet long, though usually not that long. Weight is up to 350 pounds.
Range: Most warmer oceans, except the Eastern Pacific, including Long Island Sound. They're the largest of the native species of sharks in the Sound.
Habitat: Found most often in coastal waters, though sand tiger sharks can sometimes be found in deeper offshore waters.
Diet: What’s not on the sand tiger shark’s menu? Although they will eat almost anything (fish, crustaceans, etc…), because they are a slow-moving shark they tend to eat very little (in proportion to their body size).
Predators: Humans and other sharks.
Description: Sand tiger sharks are light brown to grey in color, with lighter shading on their undersides. This “countershading” is a sort of camouflage that makes the animal more difficult for its prey to see. A distinguishing factor is that, unlike most other sharks, the sand tiger shark’s two dorsal fins are about the same size. And its teeth are visible at all times.
Of Interest: Sand tiger shark pups practice in vitro cannibalism. While still inside its mother, pups consume each other and any unhatched eggs until only one survives. And with only one pup born at a time, the sand tiger shark recovers slowly from population setbacks.
Common Name: Smooth dogfish shark. Dogfish are so-named because of their tendency to hunt in packs, like dogs. You may also hear a smooth dogfish referred to as a "dusky smoothhound."
Latin Name: Mustelus canis
Size: males, to 3 feet; females, to 4 feet. (PICTURED: Aquarium educator Dana August holding a male smooth dogfish shark brought up during a Maritime Aquarium Marine Life Study Cruise.)
Range: The western Atlantic, from Massachusetts down to Florida (including Long Island Sound) and from southern Brazil to northern Argentina. Also the Gulf of Mexico and Caribbean. Seasonally migrates north and south.
Habitat: Both shallow and off-shore waters
Diet: A wide variety of fish and invertebrates.
Predators: Humans and larger sharks.
Description: A long slender shark, brown or olive-gray on top and grayish-white on bottom. Front dorsal fin is slightly larger than the second. Caudal (tail) fin has a long trailing upper lobe and a small rounder lower lobe. Eyes are large, oval and – despite the animal's name – catlike. Obvious spiracle behind each eye. Short blunt teeth are made for crushing lobsters and crabs.
Conservation Status: They've been one of the most common shark species on the U.S. East Coast, but recently have become commercially targeted. Smooth dogfish are considered to be "near threatened" on the IUCN Red List of Threatened Species.
Common Name: common snapping turtle
Latin Name: (Chelydra sepentina)
Size/weight: It’s believed they can live 40 to 50 years, and generally grow to 10 to 35 pounds.
Range: Common snapping turtles are … well … common in Connecticut and New York. (In fact, they are the state reptile of New York.) They are Connecticut's largest freshwater turtle.
Habitat: Eastern Canada and the central and eastern U.S., throughout Mexico and down into Central America. They prefer still, slow and shallow waters with vegetation to hide in, but can be found at the edges of deeper lakes and rivers.
Diet: Snapping turtles will each just about anything they can catch, as well as some plants and dead animals.
Predators: Eggs and young turtles are preyed upon by raccoons, skunks, coyotes and even crows. As adults, humans.
Description: Behold, the turtle that time forgot. If other freshwater turtles species received “modernizing” makeovers over the last several hundred thousand years, the common snapping turtle apparently found them to be unnecessary. These creatures don’t crawl up into your yard out of a pond; they crawl up out of the Early Pleistocene. But crawl up they do, especially each May and June, when females leave the water to look for a place to dig a hole and lay their eggs. Baby snapping turtles will hatch two to three months later and make their way to water, where they’ll live almost their entire lives.
They have a brown-black-dark olive shell (or carapace), a big head, a sharp hooked upper jaw, and a plated tail like a dragon.
Note: Snapping turtles face a number of challenges. Many females are hit by cars as they cross roads looking for nesting spots. Eggs and young turtles are preyed upon by raccoons, skunks, coyotes and even crows. And people kill turtles out of fear, which is unnecessary. Like most wild animals, they’re aggressive only when they feel threatened – and, for snapping turtles, they’re most vulnerable when they’re out of water. (In the water, bites of unsuspecting swimmers are unheard of.)
It doesn’t seem that a turtle should be the kind of animal that can bite your finger off. But snapping turtles can (and can do it frighteningly faster than you would expect), so we can’t emphasize enough that you should never try to handle one; not even by picking one up by its dragon-like tail. If one comes into your yard, give her – and her nest – some space.
They usually don’t bask in the sun like many freshwater turtle species. They also can’t withdraw into their shell like other turtles. (Thus, snapping is their means of defense.)
Snapping turtles can be harvested in Connecticut. Regulations passed in 2013 established specific protections for snapping turtles by designating seasons, size/bag limits, gear restrictions, and other measures designed to ensure the long-term viability of Connecticut turtle populations. Turtle eggs cannot be taken and turtle nests cannot be disturbed without DEEP authorization.
You’ll find a snapping turtle in our Watershed gallery. His name is Franklin.
Common Name: Portly spider crab
Latin Name: Libinia emarginata
Size/weight: Body can be up to 4 inches in diameter with long legs extended outward increasing their overall size.
Range: Nova Scotia to Florida or Texas.
Habitat: Variety of bottom habitats in shallow and relatively deep water.
Diet: A scavenger, the spider crab finds a variety of food on the ocean floor, including dead fish and attached animals (like sea squirts), sometimes even sea stars.
Predators: Gulls and other shore birds.
Description: Brown to dull yellow with white claws; small, round, spiny body with pointy beak and long, thin legs ending in pincers of equal size and shape. Sometimes called the “decorator crab” for its habit of covering itself with seaweed, algae and other objects as a means of camouflage.
Conservation Note: Not listed as endangered or vulnerable.
Common Name: Striped bass
Latin Name: Morone saxatilis
Size/weight: typically 24-42 inches and up to 30 to 50 pounds. (The world record striped bass was landed in 2011 in Long Island Sound. It weighed almost 82 pounds and was 54 inches long.)
Range: Native to the Atlantic Ocean and its coastal tributaries, from Nova Scotia to Florida. Striped bass breed in freshwater and spend their adult lives in saltwater. Most stripers spawn in rivers from southern New York to North Carolina. While striped bass are an anadromous species (migrating from the ocean to freshwater specifically to reproduce), they are considered to be amphidromous (moving into freshwater for purposes other than spawning, such as feeding) in the Connecticut River watershed.
Habitat: Many of Connecticut's stripers are fish that spend the offseason in the deep channels of the major river systems and the Hudson River in New York. Once the water temperature reaches about 50 degrees (usually late April or early May), these fish migrate into Long Island Sound to spend the summer.
Diet: mostly fish.
Predators: Predators of small (juvenile) striped bass include bluefish, weakfish, cod and silver hake. Adult striped bass have few predators, with the possible exception of seals and sharks.
Description: They are green-gray dorsally, shading to silver below, with 6 to 8 dark stripes on both sides. Sharp spine on gill cover. Teeth on the base of the tongue are arranged in 2 parallel patches. Females are larger than males.
Note: Striped bass are one of the species most sought-after by recreational anglers. Striped bass populations decreased dramatically in the 1970s and 1980s due to overfishing, pollution and habitat loss. Strict fishing regulations have allowed striped bass numbers to rebound.
In Connecticut, stripers must be at least 28 inches long to be “keepers.” Fishermen may catch up to two per day year-round.
Seafood Watch lists striped bass as a “best choice.” However, because larger striped bass (which are older) have had more time to accumulate contaminants (such as mercury & PCBs) in their bodies, the CT DEEP advises that striped bass should not be eaten by women who are or may become pregnant, by women who are nursing and by children under age 6.
The Connecticut River is experiencing a dramatic increase in the numbers and size of stripers, to the point that striped-bass predation on other migratory fish populations in the river – including alewives, herring and juvenile Atlantic salmon – is thought to be significant. To help limit this predation, Connecticut allows fishermen to catch a limited number of smaller stripers (22 to 28 inches long) in May & June through a vouchers system.
See striped bass in the "Go Fish" exhibit, and in the "Shipwreck" and sea turtles exhibits.
