The state of New Jersey is in the northeastern United States. In the second half of the 20th century, it experienced a great deal of rapid suburbanization. Bordered by New York on the north and northeast, the Atlantic Ocean on the east, Delaware Bay and Delaware on the southwest, and the Delaware River and Pennsylvania on the west, it has several different types of geography.

Northeastern New Jersey is closest to Manhattan, New York, and the Delaware Valley contains the southwestern counties which are in the Philadelphia Metropolitan Area. Northwestern New Jersey is mountainous, wooded, and rural, and the Jersey Shore in Central and South Jersey borders the Atlantic coast. Finally, the southern interior is the Pine Barrens region which has a lower population density and has mixed oak and pine forest.

There are also several major rivers, lakes, and fishing ponds. Two major climates dominate the state, which is humid subtropical in the northeast, central, and south, and humid continental in the northwest. 19% (916,000 acres) is a wetland with 67% being freshwater, and 45% being forest.

With such diverse geography, it is natural to find many kinds of wildlife, even though the state is the fifth smallest in the area and the most densely populated. 450 species of vertebrate wildlife exist, including rattlesnakes, 90 species of mammals, 485 birds, and 134 species of freshwater fish, while over 300 species of marine fish live off the marine coast, including 28 marine mammals and 336 marines finned fish which also live in the estuaries and bays.

The official state animal of New Jersey is the horse, and there are many equine facilities and race tracks to go watch horses. Meadowlands Racetrack and Freehold Raceway are two popular race tracks, while the Horse Park of New Jersey is a common site for equine awards presentations. The horse symbolizes freedom, liberty, journeys, and the ability to ride in new directions. Not only is it very important to farming, especially for the early state settlers, but many people raise horses today. Included on the state seal, it was made the official animal in 1977 with the help of students Michael McCarthy and James Sweetman.

There are other official animals, too, with regard to specific wildlife. The black swallowtail was made the state’s official butterfly on January 11, 2016, and the bog turtle, the state’s smallest turtle, became the state’s official reptile on June 18, 2018. Both are very common animals, with the black swallowtail pollinating flowers across the state and the bog turtle living in wet meadows, bogs, and ferns state-wide. The official state bird is the Eastern Goldfinch, also called the American Goldfinch or Wild Canary, adopted on June 27, 1935.

People are likely to encounter some different rodents, including mice and rats, especially in the city. House mice, deer mice, and white-footed mice, which are nocturnal mammals, are very common. Norway Rats and Roof Rats are other rodents that are pests and can be dangerous, while voles are mostly just a nuisance. Owls are nocturnal animals and are also common, as are songbirds.

In the suburbs, people can see small mammals such as chipmunks, squirrels, rabbits, and groundhogs. The rarest sightings are nocturnal predators such as hawks, foxes, and coyotes which can be dangerous animals. Outdoors in the forests and mountains, people often encounter foxes, raccoons, beavers, white-tailed deer, groundhogs, and occasionally rattlesnakes, skunks, and black bears.

The flag of New Jersey was designed with a buff-colored background with blue as the dominant color in the coat of arms at its center. Both are the state’s colors and pay tribute to George Washington who chose these same colors for the coats worn by soldiers during the Revolutionary War.

The coat of arms at the center of the flag holds many symbols representing New Jersey.

The horse head at the top of the coat of arms represents New Jersey’s state animal signifying strength, loyalty, and freedom. The female figures are Lady Liberty and the Roman Goddess of Agriculture Ceres supporting the meaning of the words underneath of liberty and prosperity.

In the center of the coat of arms are three ploughs emphasizing the importance of agriculture to the state.

Are there any poisonous animals in New Jersey?

Yes. The difference between venom and poison is how they’re delivered, although they’re both toxic substances. Venom comes from a sting or bite, while poison comes from ingestion. While a plant can be poisonous, an animal is usually venomous, although it can also be poisonous. The pufferfish‘s poison is fatal to humans, and one pufferfish species called the smooth puffer shows up in New Jersey’s bays and rivers during summer fishing. This strange fish, while cute, is a species of blowfish that has poison in its skin. Careful handling and prepping must be done by knowledgeable chefs in order to remove the risk of poisoning.
