The killer whale, like all whales, is exceptionally intelligent, not to mention more powerful than you could ever imagine!  They are not as a rule typically dangerous to human beings but interaction with them could turn them aggressive and they then become unpredictable. They are partial to rockfish as a snack.

3. Colossal Squid

A subspecies of the grey wolf, the arctic wolf has adapted to the very harsh arctic conditions. As we know, wolves are pack animals and they search in groups for their prey.  The caribou and muskoxen are particular favorite snacks they enjoy!  They tend to avoid contact with humans and if cornered by one (why would you?) it won’t end well for the person.

5. Snow Leopard

Whilst the snow leopard usually hangs out in mountainous regions, it can also be spotted in elevated areas of the Arctic.

The grizzly bear, found in the Arctic, is one of the most lethal animals in the world. They have the most ridiculous strength and also an unbelievably powerful bite, enough to split a body in half. That’s making my eyes water! They will attack if caught off guard or if they are provoked.

10. Harp Seal

Image source: Reddit

With an unusual name, harp seals have “harp” markings over their bodies so there’s your explanation. They have to have their wits about them as they are regularly hunted by polar bears but also by humans as well who want to eat the seal meat. They get very aggressive when they see a human being.

11. Arctic Fox

A regular fox that may prowl around your backyard when nightfall sets in is not the same as an arctic fox. The arctic fox won’t run off if spotted by a human although it will only attack a person if it feels threatened. It is far more interested in catching rodents for its dinner.

12. Walrus

When you see a walrus you will immediately notice its long tusks. These are certainly not for decoration.

13. Moose

The south polar skua looks a bit like a large brown seagull, but that’s where the likeness ends.  With its hawked beak, large talons and piercing eyes, the skua is well known for its predatory, territorial and aggressive behaviour. It’s definitely one of the most dangerous species in the Arctic.

18. Arctic Scorpion

Arctic scorpions are rare. They look like creepy crawlies from an animated movie – but stay clear. This eight legged creature that live in the arctic has pincers like a crab and boy can they sting.  You would certainly know about it if you were the recipient of such a sting.  The pincers are an essential part of the scorpion’s anatomy as this is how it traps its prey. Ouch!

Narwhals have long, spiral tusks and these are used as sensory organs. The tusks can be up to eight feet long!  When provoked, this is when the narwhal can turn dangerous. It has the title of being the rarest whale in the world so let’s hope the breeding program in place works.
