bottlenose dolphins
Dolphins sleep closer to the surface of the water. They always sleep with one eye open and one eye closed and half of their brain working to spot any predators. They keep their blowhole above the water so they can breathe.
Dolphins are mammals, not amphibians, as amphibians need to be able to come onto land to breathe normally, and lay eggs. Dolphins will die on land, and don't lay eggs, just give birth in the water.
It doesn't. Dophins - just as whales - come to the surface to breathe air. Then they can stay underwater for 8 to 10 minutes before they have to come up for air again. For breathing they have a blowhole on the top of their skull.
Well,dolphins eat fish.
