Whales are marine mammals. They spend their whole lives in the sea. Unlike fish, whales don’t have gills. They must breathe through a blowhole, a dorsal opening which is the equivalent of a nostril.

Under their skin, there is a surface layer of fat (called blubber) which allows them to withstand very low water temperatures. Their bodies are adapted to marine life.
