I like all animals but my favourite one is a whale. I like to read something about them and to watch films on TV.
Whales are not fish; they are the biggest sea animals on our planet.
They can be found in all the oceans.
The word ‘whale’ comes from the Greek language and is translated as a sea monster.
They live about 30 to 50 years and some of them even more than that.
There are different kinds of whales: some of them are very big. Blue whales, for example, are about 30 metres long and can weigh up to 150 tons. Other kinds are about 5 metres long and weigh about 4 tons.
The can dive as deep as 1 kilometer, not more.
They can swim under water from 10 up to 40 minutes, and then they must come to the surface of the water to breathe.
Whales can develop speed up to 20 and even 40 km/h. (kilometers per hour)
Some kinds of whales have teeth and one tooth weighs 1 kilogramme.
Whales feed on marine plankton, mollusks, fish, and krill. Some kinds eat sea animals: seals, penguins, etc.
People kill whales for their fat and whalebone.
