Most Dangerous Animals In North Carolina That Are Deadly

North Carolina is the 9th most populous state in the United States of America, and it is located in the southeastern areas.

It promises numerous attractions for tourists, including wildlife that’s both rich and diverse.

Where there are many animals, you should expect to find creatures that aren’t receptive to humans.

In this article, we’ll look into the ten most dangerous animals in North Carolina, which include the ones listed above. We’ll also give tips for anyone who wishes to explore the wildlife. 

What are the Most Dangerous Animals in North Carolina 

1. American Alligators

  • Scientific name: Alligator mississippiensis 
  • Classification: Reptile 
  • Habitat: Swamp, stream, rivers 
  • Diet: Carnivore 
  • Conservation status: Least Concern

The American alligator is one out of two alligator species, the other being the Chinese Alligator.

The American alligator is a species that can be found in Argentina, and it shouldn’t be confused with the American crocodile; the latter is a different animal. 

Alligators often seem disinterested in humans, but make no mistake, this reptile can attack just as much as a crocodile would.

The alligator isn’t picky of prey, so it can consider you as one. This animal demands extreme caution. 

2. Tiger Sharks

  • Classification: Cartilaginous fish 
  • Habitat: Deep waters 
  • Diet: Carnivore 
  • Conservation status: Near Threatened 

There are many shark species in North Carolina, and the tiger shark is the scariest of them all.

It is huge, predatory, and has the characteristic shark jaws that have fueled the reputation of these fishes as maniacal beasts. This reputation is overrated, but not completely false.

According to a study, the tiger shark can attack you at a whim, even if you don’t provoke it. It has been responsible for more than 100 attacks, of which a couple was fatal.

The only shark species that attack people more than the tiger shark is the great white shark.

3. Eastern Diamondback Rattlesnake

Eastern Diamondback Rattlesnake (Crotalus adamanteus)
  • Scientific name: Crotalus adamanteus 
  • Classification: Reptile 
  • Habitat: 
  • Diet: Carnivore 
  • Conservation status: Least Concern 

There are three rattlesnake species in North Carolina: the Timber rattlesnake, the pigmy, and the eastern diamondback.

All three have varying levels of danger, with the eastern diamondback being the most dangerous. This is why we picked it for our list. 

The eastern diamondback rattlesnake is highly venomous and is classified as the most venomous snake in the American continent. It is also the largest rattlesnake.

Though it is not aggressive, the eastern diamondback rattlesnake can inflict damage, and even kill

4. Eastern Copperhead

Eastern Copperhead Snake (Agkistrodon contortix)
  • Scientific name: Agkistrodon contortix
  • Classification: Reptile 
  • Habitat: Deciduous forest, mixed woodlands 
  • Diet: Carnivore 
  • Conservation status: Least Concern

The eastern copperhead—simply called the copperhead—is a snake endemic to North America, particularly the east.

This snake looks pleasant, but beauty is deceptive. In this case, it is even dangerous and deadly.

The eastern copperhead is a pit viper, and you guessed right, it has a high level of venom, just like other vipers.

The bites are not usually fatal, but it still requires medical checkup as the venom has effects. These include extreme pain, throbbing, severe nausea, and swelling.

Fortunately, the eastern copperhead isn’t aggressive, but be careful to not provoke this dangerous reptile.  

5. Cottonmouth

  • Scientific name: Agkistrodon piscivorus 
  • Classification: Reptile 
  • Habitat: Creeks, marshes, streams, swamps 
  • Diet: Carnivore 
  • Conservation status: Least Concern 

The cottonmouth also goes by the names water mocassin, black mocassin, viper, and swamp mocassin.

It is often associated with the eastern copperhead and is considered far more dangerous.

The cottonmouth is found around swamps, streams, and marshes, places you should be wary of visiting as snakes are often there. 

The cottonmouth’s venom is strong, though it doesn’t always kill. This venom has cytotoxic properties that can destroy tissues and even lead to an amputation.

If you’re swimming and you detect a cottonmouth, get out of the water. It can bite even in an aquatic environment. 

6. Black Bears

Black Bear (Ursus Americanus) Enjoying its Natural Environment
  • Scientific name: Ursus americanus 
  • Classification: Mammal
  • Habitat: Forests 
  • Diet: Omnivore 
  • Conservation status: Least Concern

The black bear is the smallest of all bears that can be found in America (the grizzly and the polar bear are others).

It can be found only in North America, which is why its full name is the American bear. 

Compared to other bear species, the black bear isn’t too dangerous. It hardly attacks and would prefer frightening its adversary off.

However, this doesn’t stop it from going after the said adversary if it feels threatened. Black bears can still inflict serious harm.  

7. Southern Black Widow Spider

  • Scientific name: Latrodectus mactans 
  • Classification: Arachnid 
  • Habitat: Rock piles, rodent burrows, hollow tree stumps 
  • Diet: Carnivore 
  • Conservation status: Least Concern 

The southern black widow is also called the black widow or the shoe button spider. It is one out of several black widow species, and they’re spread all over the world.

The southern black widow is found in the United States, in North Carolina, South Carolina, and other states like Texas.

Like all black widows, the southern black widow spider stays away from humans and isn’t aggressive.

However, it is venomous, and the venom can lead to lacrodectism, an illness caused by the bite of a black widow spider and other related species. 

8. Brown Recluse Spider

Brown Recluse Spider on Wooden Board
  • Scientific name: Loxosceles reclusa 
  • Classification: Arachnid
  • Habitat: Woodpiles, sheds, garages 
  • Diet: Carnivore 
  • Conservation status: Least Concern

The brown recluse spider shares some traits similar to the southern black widow. They both have a high level of venom, and they are wary of humans.

The brown recluse solitary nature earned it the name, and that’s the only fortunate part of this spider.

The bad news is that the brown recluse’s venom is strong enough to get you hospitalized. Symptoms include pain, body aches, fever, and a bite wound.

This spider only bites when threatened, so be careful about putting your hands into places where the spider might be. 

9. White-tailed Deer

White-tailed Deer (Odoceilous virginianus)
  • Scientific name: Odoceilous virginianus
  • Classification: Mammal 
  • Habitat: cropland, pastureland, brushland
  • Diet: Herbivore 
  • Conservation status: Least Concern

You might be surprised to see a deer on the list. How is a peaceful herbivore dangerous?

The answer lies in auto-related accidents. According to statistics, deers are responsible for more than 10,000 car accidents in a year.

That’s enough to classify them as risky, even though they aren’t aggressive.

These accidents tend to happen in the early morning hours and early evening. While driving, do put on your seatbelt and respect speed limits. 

10. Portuguese Man O’ War

Portuguese Man o' War (Physalia physalis)
  • Scientific name: Physalia physalis 
  • Classification: Fish
  • Habitat: Tropical and subtropical waters 
  • Diet: Carnivore 
  • Conservation status: Common

Also called the man-of-war, the Portuguese man o’ war is often found in the Atlantic Ocean or the Pacific Ocean, and it is one of the most dangerous animals you’d ever encounter at sea.

The Portuguese man o’ war has tentacles that sting and are filled with venom. These tentacles are meant to capture prey but can be used as a weapon on humans.

The pain it causes is described as severe, though it isn’t long-lasting, depending on the individual.

In rare cases, the venom can be fatal. You need to be careful while swimming, and if you get stung, do not hesitate to get checked.
