A young bear is commonly referred to as a cub. This term applies to several species of bears, including black bears, grizzly bears, and polar bears. Bear cubs are born blind, hairless, and highly dependent on their mothers for survival during their early months. They typically stay with their mothers for one to two years, during which time they learn essential survival skills, such as foraging for food and recognizing threats in their environment. Cubs are playful and curious, qualities that help them develop the necessary behaviors for adulthood.
