Whales are one of the most amazing creatures that live on the planet. They inhabit all oceans of the world. Whales belong to the order Cetacea, which means that they are mammals fully adapted to aquatic life. Like all cetaceans, including dolphins and porpoises, #whales are descendants of land-living animals which returned to water after living millions of years in land.
There are two types of whales that are identified by scientists, baleen whales and toothed whales, having each of these categories many sub species. You can easily identify which category a whale belongs based on its feeding and physical
characteristics.
Whales have their own hierarchy in their groups that is very closely followed. They are excellent parents to their offspring, and they are able to communicate with a variety of sounds. If you get the chance to closely observe whales you will quickly understand how they value their relationships with each other.
Type of Whales
Cetaceans are divided into either toothed species or baleen species. Some toothed species have upper and lower rows of teeth, some have teeth on their lower jaw only, and the narwhal has a single, long. tooth which is usually considered to be a tusk. In contrast, baleen whales have no teeth. They filter-feed, ‘sieving’ small marine organisms such as krill through fringed plates of baleen. Like our nails and hair, baleen is made of a protein called keratin.
