The seahorse is a fish, which taxonomically belongs to the order Scleractinia.

Because it breathes through gills, has a vertebrae, dorsal, pectoral and caudal fins, and is named for its head, which resembles a horse's head. The seahorse's tail is elongated, four-pronged, and can be curled.

This allows the seahorse to hook onto seaweed with its tail and stand upright in the water. Instead of scales, the seahorse's body is clothed in hard, ring-like bony plates, and some of the links bear protrusions.

Seahorse diet:

Seahorses devour their food by the stretching of the gill covers and muzzle, and the size of the bait does not exceed the diameter of the muzzle. The type and freshness of the bait has a certain selectivity. The seahorse's foraging sight distance is only about 1 meter, so the bait should be thrown in the frequent cluster.

Natural sea area seahorses mainly feed on small crustaceans, mainly flexopods, trapezius barnacle larvae, shrimp larvae and adults, firefly shrimp, mysid shrimp and hook shrimp and so on. In captivity, the best results are obtained by feeding on mysid shrimp and cherry shrimp, followed by pedipedes and telopods. Freshwater branches and horns can also be eaten, but care should be taken to avoid rapid death in seawater to pollute the water quality.
