My Life as a Blue Whale
I am the largest and heaviest animal on earth. My weight can be as much as 200 tons. Many people like watching me swim, and they think it is one of the most beautiful things to see.
I live in all oceans except the Arctic Ocean. I eat a lot, but I only feed on some of the tiniest animals in the ocean. Every day, I can eat around four tons of them.
I can live up to 90 years. When my life comes to an end at sea, my body becomes food for many kinds of animals living in and around the sea. This "gift" from me can last for over a year and helps to create a lively and healthy ecosystem. I play an important role in the world, so I hope humans could protect me.
