I've just read a book about Blue Whales. Blue Whales are endangered and unless people protect them they will become extinct. Whales are huge swimming mammals. They spend all their lives in the ocean. They have to come up to the surface to breathe air. There are 83 species of whale. The largest whale is the Blue Whale. Also I learnt that Blue Whales are the largest animals that have ever lived. I wonder if this is true? Anyways, people need to protect the Blue Whale so it doesn't become extinct. This report was written by Anim.
