Blue Whales Giant Mammals
A Whale of an Animal The blue whale is the biggest animal on Earth. It is longer than three school buses. It is as heavy as thirty-three elephants!
Look Out for the Spout A blue whale has two holes on top of its head. The whale uses the holes to breathe.
The blue whale swims to the surface of the ocean. Water and air shoot up from the holes!
Listen for the Song Blue whales sing as they swim. Whale songs are low and loud. The song can be heard far away.
Filling Up on Small Stuff Blue whales eat tiny animals and plants. Blue whales dive to find food.
