The Blue Whale grows over 30 meters long and weighs over 200 tons. It is far bigger than even the biggest dinosaur. Its tongue weighs as much as an elephant. Its heart is the size of a car. Some of its blood vessels are so wide that you could swim down them. Its tail alone is the width of a small aircraft’s wings.
