Polar bears are the largest land predators on Earth, with adult males weighing up to 1,500 pounds.
They are excellent swimmers and can swim for long distances at a time, reaching speeds of up to 6 mph.
Polar bears are typically found in the Arctic Circle, where they hunt for seals and other marine animals.
Despite their thick fur, polar bears are actually quite sensitive to heat and can overheat quickly in warm temperatures.
Polar bears are classified as a vulnerable species, with their population declining due to climate change and other human activities.
