Dolphin 海豚 (4)

Dolphins spend a lot of time hunting for food. And they are always on the lookout for danger. But sometimes dolphins just want to have fun. Dolphins make up all kinds of games. Toss seaweed into the air and try to catch it. Ride along storm waves or waves breaking near a beach. Or chase each other through the water.

The most amazing dolphin of all is the orca, also known as the killer whale. The orca wins almost every record-setting award in the dolphin category. An orca eats everything from sea turtles and penguins to seals and sharks. A killer whale can swim seven times faster than an Olympic swimmer! A killer whale can live up to 90 years.

By learning about these friendly marine mammals, humans are helping to protect dolphins and the waters they live in.
