The Blue Whale
The blue whale is the largest and heaviest animal on earth. It can weigh as much as 200 tons. Many people like watching blue whales swim，and they think it is one of the most beautiful things to see. Blue whales live in all oceans except the Arctic Ocean.
They eat a lot，but they eat some of the tiniest animals in the ocean. A blue whale can eat around four tons of these a day.
Blue whales can live up to 90 years. When a blue whale dies at sea，it becomes food for many kinds of animals living in and around the sea. This food lasts for over a year and it helps to create a lively and healthy ecosystem. Blue whales play an important role in our world，so we must protect them.
