Instead of teeth, they have long horny plates edged with bristle-like fibres that strain small marine animals from seawater. The other group includes the toothed whales or Odontocetes, with around 72 species including the beaked whales, killer whales, pilot whales, dolphins and porpoises.

There are several differences between their blowholes. Baleen whales have two blowholes, while the toothed whales, and subsequently dolphins and porpoises only have one. The structure of dolphin blowholes is also different from both whales and porpoises, which allows them to make a variety of whistle sounds to communicate with others.

Baleen whales have baleen plates in their mouths instead of teeth which allow them to filter feed. Their baleen, also known as whalebone, is not made of bone at all. It is made of keratin similar to our fingernails and grows downwards from the upper jaw of most large whales. When baleen whales open their mouths, water and prey, such as krill or small fish upon which they feed, pour in.

Toothed whales, including dolphins and porpoises, are usually smaller than baleen whales and have one blowhole. T oothed whales are selective eaters and often hunt down individual animals, such as fish, squid, seals or sea lions.

Dolphins and porpoises all have teeth and rather confusingly are known as ‘toothed whales’ too! Another obvious difference between baleen and toothed whales is the number of blowholes on top of their head; baleen whales have two whereas toothed whales have one.
