🍼 Polar bear cub
Also known as: bear cub, cub
A bear cub; here a polar bear cub, which grows up in the den on milk alone.
Polar bear cub is the young of a polar bear, which grows in a den during its first months. This is about a polar bear cub. In autumn a pregnant female digs a den in snow or in the ground. That is where she gives birth in winter. The cubs are born very small: about 600 grams and roughly 30 cm long. They are blind, toothless and covered in short soft fur. Their eyes open after about a month.
All winter the cubs suckle their mother's very fatty milk and grow fast. The mother eats nothing during this time and lives off her stored fat. The family leaves the den between late February and early April. By then the cubs already weigh 10–15 kg. The family stays near the den for about two weeks and then heads out onto the sea ice.
The cubs drink milk for a long time. They are weaned at two to two and a half years. That is why a female usually has cubs only once every three years.
