Magnificent frigatebirds eat mainly fish, as well as squid, jellyfish, and crustaceans. However, their diet can greatly vary due to food availability and preferred hunting technique.
Feeding Sooty Shearwaters forage by plunging into the water from low flight, making shallow dives from the surface, or seizing prey at or just below the surface, to catch various small fish, shrimp and other crustaceans, squid, and jellyfish.
Sunfish eat jellyfishes, salps, comb jellies, zooplankton, squid, and crustaceans. They live in the Eastern Pacific and Atlantic.
Habits: Leatherbacks feed almost exclusively on jellyfish, but also eat tunicates and seaweed. The mouth and esophagus have backward-pointing spines that aid in swallowing jellyfish.

One sure-fire clue that you are in tropical water is the presence of a jellyfish-like creature known as the Portuguese Man-of-War. It is actually not a true jellyfish, but a member of a closely-related group called the siphonophora.
The Cnidarians include the hydroids, jellyfish, anemones, and corals. All Cnidarians use tentacles which have stinging cells which are used to subdue and capture food.
The majority of animals more complex than jellyfish and other Cnidarians are split into two groups, the protostomes and deuterostomes, and chordates are deuterostomes.
They feed on jellyfish and other oceanic invertebrates. Leatherbacks are strong swimmers, and tagged individuals have been known to migrate thousands of miles across ocean basins.

The subclass Scyphomedusae contains a number of animals which in the adult condition are medusae or jellyfishes (see Medusa), exclusively marine in habitat and found in all seas.
Common molas eat mainly jellyfish. They "chew" them by sucking them in so that the jellyfish gets caught on special teeth (pharyngeal teeth) in their throat. The fish then alternately sucks and spits the jellyfish, thereby shredding it on the teeth.

Parakeet Auklet: Eats jellyfish, krill, and small fish; forages by diving from the surface and pursuing prey underwater.
Vocalization
Parakeet Auklet: Generally silent; gives clear whistles while in breeding colonies.
Spadefish will target planktonic prey items (including jellyfish and copepods) as well as benthic prey items (including hydroids, sponges, ascidians, anthozoans, and polychaetes). They, in turn, are prey items for finfish, sharks, and rays.
This nocturnal feeder eats small fish, shrimp, plankton, and jellyfish. Only 14 examples of this rare species have been found, mostly in the Pacific Ocean! ...
Adults feed on fish, squid, octopus, crustaceans and jellyfish. In some areas they are drawn towards discards from fishing fleets, which puts them at risk of being killed on long-line fishing hooks.

As adults, however, greens are the only herbivorous (vegetarian) sea turtle, feeding on sea grasses and algae.
April and early May seem to be the period of the leatherback migration into Georgia waters. This concentration of turtles coincides with the occurrence of vast numbers of the cannonball jellyfish.
