Seahorse; a small marine fîsh of the genus Hippocampus, in the family Syngnathidae, closely related to the pipefish. It is widely distributed in the temperate and tropical waters of the world. The sea horse is so named because of its distinctively horselike head, general body shape, and upright position. It is covered with bony plates arranged in rings and has an elongated tubiform snout and a toothless mouth. The sea horse lacks a caudal fin but has small pectoral, dorsal, and anal fins. It also has a prehensile tail, which it uses to attach itself to seaweed or other available supports.
The sea horse is capable of a variety of color changes, enabling it to be relatively inconspicuous in its natural habitat. An Australian species has numerous dermal flaps covering its body and tail, giving it a remarkable resemblance to the seaweed in which it lives.
Most adult sea horses are about 6 inches (15 cm) long, but sizes may range from 2 inches (5 cm) to 12 inches (30 cm). The best known species is the common sea horse (H. hudsorıicus), found olf the Atlantic coast of the United States, southward from Cape Cod.
The male sea horse has a brood pouch on its abdomen into which the female places eggs for hatching. As many as 200 young escape from this pouch after an incubation period of 40 to 50 days. The diet of the sea horse consists of plankton animals, primarily small crustaceans.
The sea horse has long been a popular aquarium fîsh, but is difficult to maintain because it must be supplied with running sea water.
