Did you know that a dolphin’s skin sheds constantly? This makes is so algae and bacteria can’t stick to them.

Dolphins are a mammal and breath air through their dorsal blowhole.

Dolphins are very vocal and can make many sounds. They use certain sounds, such as the click, for sonar. They can tell through the echoes, how far they are away from something.

Most dolphins are about 6 feet long, but the bottle-nose dolphin can be over 9 feet long. The smallest dolphin is a bufeo, which is about 3 feet 9 inches.

Dolphins can hold their breath and dive over 1,000 feet deep.

On the average, a dolphin can eat over 50 pounds of food per day. Wild dolphins eat live fish, while most captive dolphins eat them prepared.

A female dolphin’s pregnancy lasts between 11 and 12 months. She will nurse her baby for over a year.

Some dolphins travel in groups of over 1,000. Dolphins are found all over the world.
