Whales are sea animals. They live in the sea. They eat small fish and other sea animals. They can sing songs and sing very well. They are very interesting. One interesting fact is that some kinds have teeth.
For example
Another interesting fact is that they can jump high out of the water. But now some kinds of whales are in danger because there is more and more water pollution and people catch whales for meat, fat and oil.
