Blue Whales are a very special class of Whales who come from the order Cetacea, which includes whales, dolphins as well as porpoises. Whales are split into 2 suborders: baleen and also toothed whales. Baleen whales have a comb-like edge, called a Baleen, on the upper jaw, which is made use of to filter plankton, in addition to little fish and also crustaceans. They are the largest varieties of the whale. The blue whale length can be up to 29.9 metres (98 ft). Blue whale should not be confused with ORCA ((Orcinus orca) which are killer whale.
Toothed whales have teeth and prey on fish, squid, other whales as well as aquatic mammals. They sense their surrounding setting through echolocation. Like all creatures, whales take a breath air right into the lungs, are warm-blooded, feed their young milk and have some (although very little) hair. Their bodies look like the structured type of a fish, while the forelimbs or flippers are paddle-shaped. The tail fins, or flukes, enable whales to drive themselves with the water. The majority of types of whale have a fin on their backs referred to as a dorsal fin.
