Polar Bear Cubs. Totally dependent on their mothers, newborn cubs are blind, toothless, and covered with soft white fur. They weigh little more than 1/2 kg (1 lb) and are just 30-35 cm long (12 to 14 in). The cubs grow rapidly on their mother's rich milk (31% fat) and continue nursing for at least 20 months.
