Nature

Whales dolphins and porpoise are known as Cetacean. They are placed in order Cetacean from the Greek ‘Ketos’ and the latin ‘Cetus’ which means large marine creature, sea monster. They are very hard to study as they spend most of their time in under water. However our understanding in these fascinating animals has increased and they are now more respected than ever before.

Currently there are about 78 species of living cetacean. They are divided into two suborders, the baleen, Mysticeti and the toothed, Odontoceti whales. This depends mainly on their feeding apparatus.
