1. How does polar bears know when to hunt and when not to?Polar bears like to hunt seals and use sea ice as their habitat. They know when to search for seals and when they are not in the right place. Generally, a polar bear will search for a seal every two or three weeks. In the summer, polar bears in the Beaufort Sea have learned to avoid hunting at high tide. When a polar bear smells the scent of a seal, he heads for the sea ice. He is still able to hunt seals if they are right below the ice. Polar bears first learned to avoid digging for white bears and contaminating pups, and later learned not to hunt sandhill and ringed seals. They passed on this information to their offspring.
3. How does polar bear digestion work?Polar bears are able to digest most foods usually found in their diet. They have no teeth, so they digest their food using their long, sticky tongue to pull apart the tough, fibrous plant and animal tissues in their meals. Polar bears typically eat anything new they encounter — including garbage, fish, and the remains of other animals. They are able to eat because their tongue is long and sticky so they can efficiently grab and pull off food.
2. How does polar bear communication work?Polar bears communicate almost entirely through scent. They communicate through special scents and secretions produced in specific glands. When a polar bear feels threatened or needs to communicate, he rolls onto his back, exposing the skin on his belly. His subcutaneous glands are exposed and he gives off the scent that he wants to communicate. He also lifts his hind legs, allowing his anal glands to flow.
8. Do polar bears eat seals?The primary food for polar bears in the Arctic is killed seals, which the bears can wade through the ice to reach. The seals are then killed by the polar bear. In other parts of the Arctic, the primary food source is fish. So, polar bears can eat everything from eels to salmon to squid to Arctic cod. 7211a4ac4a
