Is a polar bear a monotreme?

Answer 1

No; a polar bear is not a monotreme. A monotreme is a mammal which lays eggs. Polar bears do not lay eggs, but give birth to live young.

There are only three monotremes: the platypus, the short-beaked echidna and the long-beaked echidna.

Answer 2

Yes. Polar bears suckle their young, have hair or fur and are warm-blooded, maintaining their internal body heat regardless of the outside temperature. Polar bears are a member of the bear family (Ursidae) and are sometimes seen as a marine mammal because it spends a lot of time at sea.

Polar bears usually give birth to two cubs, born weighing less than a kilogram each. They are nursed for several months until they are between 10 and 15 kg. and are ready to leave their den. The mother polar bear does not eat for up to eight months while caring for her newborns in a den of ice and snow. The cubs will follow the mother for about another two years.
