Sea Mammals

Over a period of tens of millions of years, several different groups of air-breathing mammals have returned to life in the sea. Those that first did so, have become remarkably adapted to an aquatic environment (whales,dolphins and manatees) while those that have returned to the sea more recently remain partly dependent upon the land for warming themselves and for giving birth (seals, sea lions, sea otters).
