media type="custom" key="13539860"

Dolphins are marine animals closely related to whales and porpoises.  There are 36 different kinds of ocean dolphins and 5 species of river dolphins.  Dolphins live in pods formed by 10 to 12 indidviduals. They mostly eat squid and fish. All dolphins grow to 4ft-6ft tall and weigh 40kg-60kg. They are very friendly and intelligent. Dolphins can live to be 50 years old. Small dolphins reach 35-40 km (22-25 mi) per hour but the orca or killer whale, which is in fact the world's largest dolphin, reaches 50 km (31 mi) per hour, which is a lot in the water.  The bottlenose dophin is the most common species.
