Cetaceans (dolphins and whales) do not drink as such. They do swallow water but are adapted to be able to remove the salt from this and excrete it (the salt). They gain the water they need for metabolism from their food. Whale kidneys can remove surplus salt from blood.
Salt-water fishes' kidneys can filter water.

There are in fact a fair number of animals that rarely (if ever) take in water directly (mostly desert dwellers), instead getting all the water they need from metabolic water and from the food they eat. The best examples are perhaps the various species of kangaroo rat of North America, and the physically similar jerboas of the old world.
And of course it depends on what you mean as well. Many animals like frogs that live in moist environments don't ever drink water because they can absorb all the water they need through their skin.
