In the ocean there are many animals such as fish, squid, sharks, eels, manta rays, mollusks, dolphins, whales, and clams.   

They have many thing to eat like fish, krill, and plankton

The best known of its family, the Atlantic Salmon is a long-bodied, rounded fish with a slightly forked tail. There are some salmon in inland lakes, but most are migratory, moving from their natal river out to sea and then back to the river to spawn. The salmon enter the river at different times but all spawn in the winter. Breeding males develop hooked protuberances on their lower jaws.

The basking shark is the second-largest living species of fish. It shares the streamlined body shape of other sharks but is distinguished by its extra-large gill slits. It feeds entirely on plankton which it sieves from the water by means of comb like bristles on its gill arches.

An active predator, the Greenland halibut hunts in mid-waters rather than on the seabed, feeding on fish, crustaceans and squid. In keeping with its habits, it is more symmetrical in body form than most flatfishes and has a blind side almost as dark as its eyed side.
