Facts Dolphins can swim up to 260 miles a day. There are 36 different types of ocean dolphins and 5 river dolphins. Different types of dolphins eat different things. Dolphins are marine mammals closely related to whales and porpoises. Dolphins have to breath air. When they want to sleep half of their brain is awake. Sometimes they sleep close to the surface with their blow hole sticking out of the water.
More Facts Dolphins are typically 8ft long. They have a long lifespan. The bottle nose can live 40yrs and the orca (closely related) can be 70 or 80 yrs old. They mostly live in shallow areas of tropical climates and oceans. Dolphins love to play, are very active, and are known to follow ships and leap high out of the water.
Pink River Dolphins Their brain is 40% larger than a humans. They can turn 180 degrees. They are larger than the grey dolphin. They live in the Amazon. They eat small turtles, crustaceans, crabs, catfish , and piranhas. Instead of a dorsal fin they have a hump. When they’re little they are gray as they grow up they turn pink.
Echolocation When dolphins are in murky waters or in the dark parts of the ocean they can’t see. They use echolocation to find food or other dolphins. Dolphins can make a high pitched clicking sound. When the click hits a object some of the sound will echo back. By listening to the echo and estimating the time it took to come back they can guess the distance of the object.
