I believe most whales live in the open ocean just as a matter of size (swimming too near to the shore leads to beached whales). Lots of dolphins on the otherhand enjoy swimming near shore and, being smaller, can do so easier than the larger dolphins/whales. A smaller creature that leaves in the open ocean however is plankton (though I'm not 100% positive this is truly considered an animal as it's also been called a plant or a bacteria); these creatures float along in the ocean's currents and act as a food supply for those large whales with balleen.

A variety of fish also live in the open ocean. Capable of breathing underwater, these fish have no need for a floor-like surface or to reach the water's surface. In fact, the majority of animals in the open ocean are those who do not need air for survival with the main exception of large whales and dolphins.
