To adapt to climate change, which is causing the earth to get hotter and ice melt faster, polar bears are learning how to swim long distances to find their prey.

Pau Souders wildlife photographer made a set of photos during a trip to Hudson Bay, Canada last November.

Polar bears are the largest predator on land.They eat fish, seals and sea elephants.When food is scarce, this bear even eats seaweed.

A polar bear bared a fierce fang when the photographer was taking a picture of it.This bear spends most of its time traveling on ice to hunt.

The number of polar bears is declining rapidly as the earth warms, narrowing the area of ​​ice, affecting the habitat of aquatic animals such as seals, the main source of polar bears.

People killed bears to get leather for shoes, hats, clothes, and carpets.In 1965, the countries bordering the Arctic were meeting and decided to ban the hunting of pregnant bears to protect the number of polar bears.

Mother bears pregnant between 195 and 265 days.They often burrow to prepare to give birth in the fall.

Adult male bears usually weigh 400 - 600kg, sometimes with more than 800kg.Females are about half as big as males.Their average life expectancy is 15 to 20 years.
