Lesson Excerpt:

Did you know that dolphins are whales? It's true. Dolphins are a kind of whale known as toothed whales. They are marine mammals that live mostly in shallow seas and feed on a variety of fish. Dolphins are very intelligent animals. They are also playful and seem to enjoy the company of people.

Dolphins are very fast swimmers. They have tail fins called flukes that are designed to propel them through the water and fins called pectoral fins that they use to change direction. Like all whales, dolphins breathe through a blowhole on top of their heads. They can hold their breath underwater for 10-20 minutes before having to come to the surface to breathe. Most dolphins have excellent hearing and eyesight. They use different sounds to communicate with each other. They also use a process called echolocation to locate objects in the water.
