Dolphins breath air through their noses, just like other mammals. Their noses are called spouts and are located on top of their heads, so they can breath air while keeping virtually all of their bodies in the water.

Dolphins must look out for two of the seas bigest predators. The orca which is also known as the killer whale and sharks. These animals will try to attack a school of dolphins. Even take one away! The dolphins defend themselves by ramming their heads into the gills of a shark or circling an orca til it gets dizzy and swims away.
Yes, dolphins have eyes. Their eyes are located on the sides of their heads and are adapted for underwater vision. Dolphins rely on their eyesight, along with echolocation, to navigate and hunt in the ocean.
