Most Dangerous Animals On The Planet

The dangerous animals on this list are ones that even animal lovers would not want to encounter. Here are some of the most dangerous animals on Earth.

Blue Ringed Octopus

The Blue Ringed Octopus is only the size of a golf ball, but has the venom to paralyze its prey within minutes. Not only that, but there is no known remedy for its poison.

The blue ringed octopus can be found in coral reeds in the Pacific and Indian oceans. They change the color of their blue and black rings when threatened. These deadly creatures only live for around two years, dependent on a few different factors like nutrition and environment.


Cassowaries are flightless birds that are native to tropical forests in New Guinea and northeastern Australia. They have been called "the world's most dangerous bird."

The Cassowary does not bite, but instead has long claws that it uses as weapons. The center of its three toes have a long nail that is capable of easily severing an arm. This is one bird you definitely do not want to run into.

Polar Bear

The polar bear will eat almost anything that has meat on it. They aren't known to kill humans, but this could be primarily because they live in areas with little to no human populations. Polar bears live within the Arctic Circle and spend their time hunting seals.

Polar bears look cute on TV, and Coca-Cola even uses them in their marketing campaigns, but don't let their looks deceive you. They can weigh up to 1500+ pounds and are able to travel quickly thanks to their long limbs.

Green Anaconda

The Amazon is home to many dangerous creatures, including the green anaconda. It's one of the world's largest and heaviest snakes. They are known to grow up to 15 feet, and their skin usually features a yellow stripe on one side and black spots.

Green anacondas typically lurk inside water, so they can sneak up on their prey. Their known to live in marshes, swamps, and can usually be found in tropical rain forests. They wrap around and constrict their pray, and then swallow them whole.

Poison Dart Frog

Another species found in tropical humid regions of South and Central America is the poison dart frog. They are very small but extremely deadly, with their poisonous enough to kill up to 10 people. These frogs can weigh as little as one ounce, and be a small as half an inch.

The poison from these frogs has been known to be used in poison arrows and poison darts, hence the name 'poison dart frog'. Their bright color serves as a warning for predators to stay far away.

Bullet Ant

The bullet ant's bite can be compared to the throbbing felt by a bullet wound. A bite from a bullet ant will burn and throb for up to twenty-four hours.

Bullet ants can be found in rain forests in Central America. The ants can measure up to one inch. Their feet are stick which allows them to climb on nearly any surface.


Millipedes can be found in most areas except for extremely cold climates. They typically dwell in dead wood or soil, and prefer humid climates. They excrete a poisoning liquid through their pores.

Millipedes have been used to treat some medical conditions like fevers and hemorrhoids in some cultures. They are not dangerous to humans, but their poison can be used in poison tipped arrows.

Mediterranean Black Widow

Just by looking at this spider, it's easy to see how dangerous it is. The Mediterranean Black Widow has large venom glands and is more dangerous than other Black Widows. This is an animal to be avoided at all costs, as the bites are known to be very harmful to humans in particular.

The female can be distinguished by the male from its glossy black color with an orange shape on their bellies. Black widows get their name from the females eating the males after mating. Males find their partners through the scent in a female black widow's web, which can tell them whether they have eaten or not already.
