You might think these animals are cute but they're amongst the deadliest on Earth

Dolphins may seem friendly, but don't let their smiles deceive you.

It's true researchers found several instances where dolphins gifted locals in Australia fish or octopuses and that they worked side-by-side with Brazilian fishermen. But dolphins are also known to try to drown or forcibly copulate with humans.

Slow lorises may look cuddly and adorable, but they mimic cobra snakes — and have venom and a bite that can cause anaphylactic shock or even death in humans.

As climate change continues to threaten polar bear habitats, these furry creatures have moved into populated human areas. They are known to be deadly, and attacks on humans have increased in recent years.

If you do happen to run into a polar bear, using bear spray, carrying a gun, or getting naked as a distraction are your best options to protect yourself, according to the New York Post.

Weighing up to 840 pounds, the leopard seal has rarely attacked humans. They are, however, the only seals that are known to kill other mammals, including other seals.

Pandas may put on a facade of being somewhat endearing, peaceful, and lazy, but humans shouldn't get too close. They're slow, but their claws and teeth are powerful.

Moose can grow up to be 5 to 6.5 feet tall (at the shoulders) and weigh up to 1,800 pounds.

"Moose are not normally aggressive; however, they can become aggressive when they are harassed by people, dogs, and traffic, or when hungry and tired, especially in winter when they must walk through deep snow," according to the Alaska Department of Fish and Game.

Coming across a kangaroo may seem like a great photo opp, but the animals have become increasingly violent and aggressive with tourists in Australia that get too close.

Growing between 5 to 12 inches long with a tail spanning 1 to 2 inches, hedgehogs appear cute in size. But when scared or threatened, hedgehogs may expand their quills. The creatures are capable of biting humans and carrying parasites in their quills, though some people do choose to have them as pets.

These tiny and unique-looking crustaceans are feared by the fishermen community.

There are two groups of mantis shrimp — spearers and smashers, which describe how they attack their prey.

Hippopotamuses have earned the spot of the deadliest mammal on the globe killing an estimated 500 humans each year. Their powerful bite can easily halve or crush a human to death.
