Behavioral Adaptations

Polar bears are a solitary animal which means they live alone. Polar bears spend most of their day sleeping, lying around, and hunting. Polar bears travel from place to place looking for food. They travel by walking on ice and snow or swimming in the ocean water. When polar bears meet up with each other, the bigger bear usually scares away the smaller bear from its territory or food. Polar bears are patient hunters and wait a long time and stalk their prey.
