Dolphins are amazing animals that live in the big blue ocean. They look like fish, but they are very different.
Dolphins are mammals, just like cats and dogs. This means they breathe air through a hole on their heads.
This hole is called a blowhole. They must come to the top of the water to get air.
Dolphins are very smart and friendly. They live in groups with their friends and family.
These groups are called pods. Dolphins in a pod look out for each other.
They like to play games in the waves. Sometimes they jump high out of the water to say hello.
Dolphins talk to each other using sounds. They make clicks, squeaks, and whistles.
Each dolphin has its own special whistle. It is like having a name that only they use.
Dolphins use sound to find things in the deep water. They send out a click and wait for it to hit a fish.
This helps them find food even when it is dark. Dolphins love to eat small fish and squid.
Dolphins are very fast swimmers. Their skin feels smooth and rubbery.
They have strong tails that move up and down. This helps them zip through the waves very quickly.
Dolphins sleep with only half of their brain at a time. One eye stays open to watch for danger.
This keeps them safe while they rest in the sea. They are some of the most loved animals in the world.
