Read the following text carefully! Dolphins are some of the most playful and intelligent animals on our planet. Even though dolphins spend their lives in the water, they are not fish, but are mammals. Dolphins can't breathe water like fish, but need to come to the surface to breath air. Dolphins are very social animals. Many dolphins travel in groups called pods. Some dolphins, like Killer Whales, live in pods of 5-30 members for their entire lives. Baby dolphins are called calves. The males are called bulls and the females are called cows. Dolphins have long snouts that typically hold around 100 teeth. They also have a blowhole on the top of their head that they use for breathing. They eat other smaller fish, but they are not limited to just fish. They eat squid, too, and some dolphins, like Killer Whales, will often eat small sea mammals like seals and penguins. Dolphins often hunt together, herding fish into packed groups or into inlets where they can be easily caught. They don't chew their food, they swallow it whole. Dolphins get the water they need from the animals they eat, rather than drinking ocean water Dolphins have excellent eyesight and hearing. Underwater they use echolocation. Echolocation is kind of like sonar where dolphins make a sound and then listen to the echo. Their hearing is so sensitive to these echoes that they can almost "see" objects in the water by hearing. This allows dolphins to locate food in cloudy or dark water. Source: ducksters.com What is echolocation for?
