Seahorses are a spectacularly peculiar and beautiful family of fishes characterized by their prehensile tails and shape, seahorses inhabit the shallow waters of many parts of the world’s tropical and temperate seas and oceans. They do not have scales like most fish, but skin that covers their body’s bony structure. There are several dozen different species of seahorses, well-known for the fact that the males carry the young. Seahorses feed primarily on very small crustaceans and invertebrates as copepods. Unfortunately, seahorse numbers are in great decline worldwide, and some face extinction.
