What eats them?
Adult seahorses are presumed to have few predators due to excellent camouflage, a sedentary lifestyle, and unappetizing bony plates and spines. They have been found in the stomachs of large pelagic fishes such as tuna and dorado, however, and are also eaten by skates and rays, penguins and other water birds. A seahorse has even appeared in the stomach of a loggerhead sea turtle. Crabs may be among the most threatening predators with damaged tails indicating a narrow escape. Young seahorses are the most vulnerable to being eaten by other fish. For some populations of seahorses human beings are the greatest predator.
