Meet Two Kinds of Whales
Many kinds of whales swim in our oceans. Read about two kinds of whales.
Toothed Whales
Their Mouths
They have sharp teeth. They hunt for fish, seals, and even other whales to eat.
[ILLUSTRATION OMITTED]
Their Heads
They each have one blowhole on the top of their heads to take in air. Then they blow air out through the blowholes.
[ILLUSTRATION OMITTED]
Their Bodies
They each have two flippers and a tail fluke to help them move through water. They also have fat under their skin to keep them warm. That thick fat is called blubber.
