Altough they live in the water, dolphins are mammals, not fish. They are intelligent, playful creatures, friendly to humans.
A newborn dolphin is about a third as long as its mummy. A mother dolphin will stay with a calf for 2 to 3 years.
Dolphins are social animals. They live and hunt in groups. They help other sick dolphins as often as they can.
Dolphins use echolocation to navigate and hunt. They communicate with each other with clicks and whistles.
Dolphins eat fish, squid and small marine life. They don't chew their food. They use their teeth to catch their prey.
Dolphins can jump as high as 6 metres out of the water. Some of them can dive as deep as 300 metres.
Dolphins have large and complex brains. They are as intelligent as dogs. Being fast learners, they are able to generalize and learn human sign language.
