New Jersey is famous for its abundance of many kinds of wildlife, particularly in rural areas.
But while many people love seeing animals in their natural habitats, not all of them are viewed quite so fondly. Encounters with certain critters can quickly turn hazardous or even deadly if residents are not careful.
From tiny insects to large mammals, here are the most dangerous animals found in New Jersey, according to World Atlas.
Coyotes in NJ
Coyotes are not outwardly aggressive but have been known to attack humans, especially when rabid.
Aggressive coyote encounters are rare, but World Atlas recommends calling animal control or police immediately if one is seen showing signs of aggression such as growling, lunging or snarling.
Eastern yellowjacket wasps in NJ
These wasps are more aggressive than other species, often flying into people or buzzing nearby when marking their territory or searching for a meal.
Wasps will sting multiple times in cases where they feel provoked or threatened, and that can cause an allergic or anaphylactic reaction.
Feral pigs in NJ
Also called wild hogs, feral pigs are invasive in New Jersey, having been introduced to the country by Spanish explorers, says the state Division of Fish and Wildlife.
New Jerseyans are advised to avoid these aggressive animals, which generally lack fear and can spread disease to humans, pets and livestock.
Black bears in NJ
The focus of the annual New Jersey bear hunt to control their population, black bears are mostly found in Sussex, Morris and Warren counties.
The species is generally non-aggressive but can intimidate people and other animals when feeling threatened.
White-tailed deer in NJ
Deer, a common sight throughout much of New Jersey, are considered dangerous
