What Do Dolphins DO?


Are dolphins fish?

Nope! Dolphins are mammals—just like bears, elephants, rabbits, dogs, and many other animals. (People are mammals, too!)


Look at the pictures throughout this book. Can you name some things dolphins do? Do any of the things that dolphins do start with the letter “d”?

What do dolphins eat?

As they swim, dolphins grab onto fish, squid, or octopus—and swallow them whole!

Do dolphins sleep?Demonstrates how a dolphin lays its face on the water's surface to sleep with one eye open.

Yes, but not the way we do. Dolphins float on one side and sleep with one eye open. After a while, they roll over to the other side and open the other eye.

Hey, how does a blowhole work?

Imagine if your nose were on top of your head. It would be like a dolphin’s blowhole! Dolphins open their blowholes to let in air. But just as you hold your nose when you go underwater, dolphins close their blowholes.
