The blue whale is the largest animal on earth. It has a long body and its length is around 25 metres. Some blue whales can even be 30 metres long. The average weight of the blue whale is 150 to 180 tons.
Among all animals, the blue whale has the biggest heart in the world. Its heart is as big as the tyre（轮胎） of a large truck.
