They are found in seas and oceans worldwide, mostly preferring the colder waters of the Arctic and Antarctic regions. Some are also found in inland lakes in Finland, Russia, and Siberia. The exceptions are the monk seals, which live in tropical waters, and the Baikal seal, which is exclusive to the freshwater lake Baikal.

Breeding can take place both on land and sea after forming a colony. Both sexes build up extra blubber reserves – the males need additional energy for courting a mate and warding off competitors, while the females need it to nurse and take care ...
