All animals that live underwater must obtain oxygen in one way or another. Fish for example have gills that move water past their blood vessels allowing oxygen to diffuse into their bloodstream. Mammals and some other animals must return to the surface of the water to breath in oxygen.
While they are under water they eat many things, other animals, algae, and detritus.
