From nature documentary to a cola bottle, the polar bear is an iconic animal. But how much do you really know about the polar bear? Is it really as big as the rumors say? How does it survive the harsh climate of the Arctic year after year? We’re here to answer all these and more.
Even though polar bears are born on land, they spend most of their life in the sea swimming between ice floes, and hunting for seals.
Their thick clear fur reflects the white snow, allowing them to blend in with their surroundings and stay warm in the cold Arctic winter. But their skin is actually black. You can see this black skin on their nose and mouth, and on the pads of their paws.
We often think of the African safari as being home to the world’s largest land predator. But in truth it’s the Arctic safari that holds the title. Followed closely by the grizzly bear, the polar bear takes the number one position with males weighing up to 700 kg (1,500 lbs) and when standing on his hind legs can be over 2 metres (9 ft.) tall.
Unlike other bears, polar bears have an elongated snout, which is perfectly adapted to warm up cold arctic air before entering their lungs.
Contrary to images found on pop cans, polar bears are only found in the Arctic, while penguins can only be found in the southern hemisphere including Antarctica. It’s an adorable animal relationship that was never meant to be.
On average, polar bears give birth to two cubs at a time.
Due to changing climates, scientists have witnessed polar bears moving further south, and meeting Grizzly bears who have been expanding their habitat north. The two bears are close enough related that they’ve been successfully breeding and creating a whole new bear species: the pizzly.
The Greek word for Arctic (arktikos) is derived from arktos, meaning “bear”. This also means that Antarctica roughly translates to “no bears”!
Polar bears are brilliantly adapted animals to the Arctic climate. The outermost layer of their fur contains guard hairs that can grow 15cm long. Below that is their thick underfur that traps in body heat and air for added insulation. And finally, polar bears use their incredible tick skin, and large pockets of blubber to stay cozy during Arctic blizzards.
Their most common form of hunting is referred to as “still-hunting” where they patiently wait next to a breathing hole for a seal to pop up. Sometimes they’re waiting for hours, with only 2 out of 10 hunts being successful.
