Whales are huge animals. They live in the sea and eat small fish and other sea life. One interesting fact is whales can jump high out of the water. Some kinds of whales are in danger because humans catch them for meat, fat and oil, and use whale parts to make things like candles and soap. Whales are also in danger from water pollution. We should protect whales by making rules on whale protection and by not putting rubbish into the sea. I think people should learn more about whales.
