Whales and dolphins are a group of mammals called cetaceans that spend their entire lives in water.

Today there are around 77 different species of cetaceans, inhabiting our oceans from the cold Antarctic Continent in the south to the Arctic Sea around the North Pole. There are two very different groups of cetaceans: Baleen whales and Toothed whales. Whales and dolphins are among the most intelligent and mysterious creatures on our earth.
