They are amazing, intelligent animals. They are warm blooded creatures (mammals) that live in oceans and rivers, and are closely related to whales and porpoises. They are well known for protecting other dolphins, and there are even stories of dolphins rescuing people.
Dolphins are fantasic swimmers and can jump out of the water. Because they are so clever and such brilliant swimmers, some people use them in dolphin shows.
We must protect dolphins as they are threatened by people killing them. Dolphins are killed for food and are killed accidently by fishermen.
