Connecticut is the third smallest state in the US, but that doesn’t mean it’s lacking in biodiversity. While roughly 60% of Connecticut is covered by forest, the rest is claimed by coasts and wetlands. Dozens of mammals, reptilians, and amphibians call the state home along with hundreds of species of birds.
Notable wildlife of Connecticut includes the badger, beaver, long-tailed weasel, and white-tail deer — but that’s just scratching the surface of the animal diversity in the state. The coasts and marshes play home to a huge marine population.
The Official Animal of Connecticut
Connecticut didn’t settle on an official state animal until 1975. The sperm whale was chosen because it played a part in the state’s history but also to raise awareness for its position as one of the rarest species on the endangered wildlife list. Connecticut was once an epicenter for the whaling industry, but the modern embrace of the sperm whale demonstrates a shift toward conservation.
Connecticut also has a state bird in the form of the American robin. Designated by the general assembly in 1943, the robin was chosen thanks to the ubiquitous presence of their songs and chirps throughout the state.
Where To Find The Top Wild Animals in Connecticut
The landmass of Connecticut may be small, but it packs in a lot of biodiversities. Coast to the east gives way to a variety of different marshlands, waterfalls, and finally dry forests and mountains.
Connecticut’s woodland ecosystem is similar to much of North America. Predators like black bears, coyotes, and red foxes hunt in search of prey like white-tail deer and snowshoe hares. The long-tailed weasel and badger also have a home here along with a number of different rodents.
The marshlands of Connecticut are unique in that they’re home to both tidal wetlands and salt marshes. While both have their own flora and fauna, woodchucks and beavers both play prominent roles in these regions along with river otters, turtles, and a number of different frogs and snakes.
The largest animal you’ll find in the waters surrounding Connecticut is the imposing sperm whale, but they aren’t the only marine life worth seeing. Gray and harbor seals can both be found along with porpoises on Connecticut’s beaches.
Highly recommended spots for wildlife sightings include:
- Meigs Point Nature Center
- Stewart B. McKinney National Wildlife Refuge
- Dennis Farm Preserve
- White Memorial Conservation Center
- Denison Pequotsepos Nature Center
The Most Dangerous Animals In Connecticut Today
It’s very unlikely that you’ll be seriously endangered walking through nature in Connecticut, but that’s not to say there aren’t some fierce predators out in the wild. The most dangerous mammal is easily the black bear. These massive bears can weigh up to 500 pounds and run up to 35 miles per hour, but it’s estimated that there are only roughly 300 of these bears in the state. Coyotes are a relatively recent addition to the ecosystem, but they can sometimes be found in the city. Bobcats are even rarer.
But the most dangerous animals are actually reptiles rather than mammals. Copperheads and timber rattlesnakes are both highly poisonous, but they both maintain very small populations in the state. The timber rattlesnake is actually endangered and mostly confined to preserves.
Largest Animal in Connecticut
The sperm whale has a long history with Connecticut – which wasn’t always a good thing for the animal made famous in Herman Melville’s “Moby Dick”. During the 1800s Connecticut ranked second only to Massachusetts in the American whaling industry. The sperm whale was the species most sought after by whalers for its oil used for lamps and other products. The great whale is now on the endangered species list.
At over 60 feet in length and weighing up to 53 tons, the sperm whale is the largest of the toothed whales and the largest animal in Connecticut waters. The sperm whale’s brain is the largest of any creature on earth – housed in a head that takes up a third of its body. These giants of the ocean live in deep water and can dive up to 10,000 feet deep. Sperm whales feed on squid, fish, octopus, sharks, and more to consume as much as 2,700 pounds of food per day.
Rarest Animal in Connecticut
The tiny piping plover is a shorebird that is native to Connecticut and is listed as a federally endangered species in the state. Measuring only 7 inches in length, this stocky little bird nests and breeds on sandy beaches along the Atlantic coast. Adult piping plovers have a short, orange bill with a black tip, a black crown stripe, and black neckband. The bird was named for its melodic, plaintive whistle.
The piping plover controls insect and small crustacean populations on beaches – making it an important part of the beach environment. The little shorebirds are often prey to bigger gulls, rats, foxes, raccoons, and domestic cats. Many of its nesting habitats have been lost to coastal development and human recreation on beaches – especially the use of off-road vehicles.
Endangered Animals In Connecticut
The most prominent endangered animals in Connecticut include:
- Least shrew – Small mammals commonly mistaken for rodents
- Sperm whale – The state animal of Connecticut, almost driven to extinction by whaling
- Barn owl – The most widely recognized breed of owl, on its way back to recovery as a species
- Leatherback sea turtle – A highly migratory species largely endangered by the fishing industry
- Bald eagle – America’s national bird, currently increasing in population after being brought to the brink
Zoos in Connecticut
Connecticut’s zoos include:
- Beardsley Zoo: Located in Bridgeport, Connecticut, Beardsley Zoo is divided into nine major exhibits including the Rainforest Building, a Predators enclosure featuring Amur leopards and tigers and a rare Andean bear, an Alligator Alley trail featuring animals of the southeastern U.S., a Hoofstock trail with animals of the great plains including bison, a New England Farmyard, a wolf exhibit, a native reptile house and an education center called Professor Beardsley’s Research Station.
- Mystic Aquarium: Located in Mystic, Connecticut, the Mystic Aquarium is one of only two U.S. facilities featuring Steller sea lions and is known for its popular outdoor Beluga whale display. Special exhibits include a ray and shark touch pool, an African penguin exhibit, a jelly gallery, and the “Jurassic Giants” dinosaur exhibit.
Wild Animals in Connecticut
Over 60% of Connecticut is forested, making it the 14th most forested state in the country. And while the native wildlife might not be strange to the average American, the diversity at play here is. And the preservation efforts covered in the state’s Wildlife Action Plan are designed to protect everything from fish to rodents and ensure that wild animals continue to have a place within Connecticut’s ecosystems.
Predators like black bears are common, but you’ll also find more regional native species like the long-tailed weasel and badger to be a common sight. The strange star-nosed mole is also native to the state, but the fact that it only lives in the wetlands means that it’s one of the rarest mammals to see.
Snakes in Connecticut
There are 14 species of snakes in Connecticut. Most are relatively small and avoid humans, however, there are two venomous states that will live within the state’s borders. Both the timber rattlesnake and copperhead are venomous, and you should be aware of what both look like while enjoying the outdoors in Connecticut!
Other common snakes in the state include the smooth green snake, the common garter snake, and the redbelly snake. If you’re near water and see a snake it’s likely the northern water snake. These water snakes live in many of Connecticut’s waterways.
Official Connecticut State Insect
The official Connecticut state insect is the European mantis. This strange-looking insect was first brought from Europe to North America to fight plant pests insects. Today, from the beginning of May or June until the arrival of winter weather, the European mantis can be spotted all over Connecticut.
This large insect is an accomplished hunter that eats moths, mosquitoes, roaches, flies, aphids, lizards, and small rodents. They are fierce predators who chase their prey after terrifying them by spreading their wings in a frightening display of power.
