Blue Whale

About Blue Whale

The great Blue Whale is the largest animal that has ever lived on Earth. They can weigh up to 150 tons, which is twice as much as the heaviest dinosaur. They have huge mouths with several hundred baleen plates hanging from their upper jaws. To feed, they take in water and then close their mouths, the plates then filter krill and other small animals from the water. Females breed when they are ten years old, and give birth once every two or three years from then on. Blue whales live mainly in cold waters.
