This majestic creature you see on the left side of your screen (if you're using a computer) is the polar bear. A humongous creature whose weight lies within 770-1,540 pounds (or 350-700 kilograms). The polar bear can run as fast as 40 km/hr. They're at the top of the food chain. They don't have any competition (besides themselves). It's main prey (during the winter) is seals. Seals, after sighting a polar bear, will usually take shelter underneath the ice, not that it helps them very much. Polar bears can break through the ice by repeatedly pounding on it with their paws. They'll rear up and slam down with all their weight and strength.
Polar bear fur isn't actually white, it just look like it. In reality, polar bear fur lacks a pigment and is transparent, which allows it to reflect light. They also have black skin, allowing them to absorb heat, which is quite helpful in a place lacking such a thing during the winter.
Female polar bears can give birth up to three cubs although usually they give birth to twins. They take shelter in giant snow mounds during the
winter, so they can keep their newborn cubs safe from the elements and predators. Although, while in the snow mound, the mother isn't able to eat, so she has to survive on her fat reserves. The cubs also have to eat, so the mother's fat reserves also go into that.
Polar bears aren't very well adapted to their environment anymore. They used to, but with global warming making the winter seasons shorter, it's becoming harder for them to eat seal and build up fat reserves so they can survive the summer. During the summer, much of the ice that they hunt on melts, forcing them to go on shore. Once they go on shore, they wander, eating what they can, which isn't always much. They'll go to garbage dumps and eat there, scavenge for dead animals, and when male polar bears encounter mother polar bears with cubs, they'll try to eat the cubs (and sometimes succeed).
