Animal Info -> Sea Animals -> Sea Whales
Whales are the large aquatic mammals in the sea. They have a streamlined body that helps them to move easily in the water. Whales breathe through the blowholes which allow the oxygen to enter the lungs. Whales are the only mammals that live entirely in the water feeding their young ones.
Like all the mammals whales have hair, they are warm blooded animals, they have a four chambered hear and also the mammary glands to feed their young ones.
The biggest of the all the whales is the blue whale which grows about 94 feet long – the height f a 9 floor building. The blue whales eat 4 tons of food each day. Except man the adult blue whale has no other predators.
The smallest of the other whales are the dwarf sperm which is short as 8.5 feet long.
Whales swim with the different mechanism that is dissimilar from the other sea animals. Whales swim through the water by moving their muscular tail up and down while the other the fishes swim by moving their tails left and right.
Whales can even do acrobatic. Whales jump high in the sky coming out of the water and then slap the water when they come down. Some whales will twirl around while they are jumping. Whales jump out of the water for playing purpose or sometimes to loosen their skin parasites. This activity of the whale is called as Breaching
The spyhopping is another activity of the whales by which the whale pokes its head out of the water and turns around taking a look around.
Lobtailing is the other activity of the whales through which the whales stick their tail out of the water, swing it around, and then slap it on to the water surface. This makes a very loud sound.
Whales migrate from the cold water grounds to the warm water grounds. They travel over a long distance of about 12,500 miles each year.
Composite whale songs can be heard under the sea. The song will last for 30 minutes. Baleen whales will sing low frequency songs and the toothed whales will whistles. The songs are used to attract their mates, to keep track of their young ones and some to locate their prey.
