Whales are mammals and are descendents from land dwelling animals but have chosen to return back to the sea after living on the land for millions of years. Whales are actually related to the hippopotamus!
Whales can be divided into two groups, Baleen Whales and Toothed Whales. As the name implies Toothed Whales have teeth and they are carnivorous. Baleen Whales filter their food through a sieve in their mouths.
Whales make amazing parents and have a special way of communicating. They communicate through echolocation and their beautiful sounds can travel for miles through the ocean. The sounds they make will bounce off different things in the water and come back to the whale. In this way the sounds are used not only for communication but also to help the whale navigate. Bats are another animal that use echolocation.
Whales inhabit all oceans of the world and it goes without saying that if we don’t look after our oceans these beautiful, peaceful creatures will join the list of species that are extinct.
