Infant polar bears are known as cubs. In the wild, they are
born in the
shelter of their mother’s den sometime between November and
January and do not emerge from their den until late March or April.
Cubs are typically playful. During their
childhood days, they
are inclined to play with their mother and siblings. For the young males,
this is their way of practicing their fighting skills. Mothers will make
sure that their cubs are safe, and that they learn all they need to know
in order to survive the frigid tundra.
