Female polar bears usually give birth to twin cubs, which stay with her for more than two years until they can hunt and survive on their own.

They give birth in winter, usually to twins. Young cubs live with their mothers for arounde 28 months to learn the survival skills of the far north. Females aggressively protect their young, but receive no help from their solitary male mates. In fact, male polar bears may even kill young of their species.

After the mother leaves, sibling cubs sometimes travel and share food together for weeks or months.

Polar Bears can be considered as marine mammals because they are directly dependent on the arctic ocean where they hunt seals. They are magnificent swimmers and strong predators that have no natural enemy that can disturb them in the cold north.
