Big and Blue

What is the biggest animal on Earth? This animal is even bigger than a dinosaur. Can you guess the animal? It is a blue whale.

Baby Blue Whales

A baby blue whale has just come out of its mother’s body. The newborn whale weighs as much as an adult elephant. The baby drinks lots of milk from the mother. Baby blue whales grow quickly.

Adult Blue Whales

Everything about an adult blue whale is big. The whale’s body is as long as three school buses. The whale’s tongue is so big that 50 people could stand on it. The whale’s heart is as big as a small car. Your heart is as big as your fist.

Blue Whales Breathe Air

Whales are mammals. All mammals breathe air into their lungs. A blue whale breathes through two holes on top of its head. These holes are called blowholes. They are close together, like your nostrils.

The whale swims to the surface of the water to breathe. The top of the whale’s head sticks out of the water. The whale blows old air out of the blowholes. Then it sucks fresh air into the blowholes.
