The word seahorse is ‘hippocampus’ in Greek, which means ‘ bent horse’. Seahorses are part of the Syngnathidae family. The snout of a seahorse is longer than other animals’ snouts. Their heads are tilted. There are thirty-five types of seahorses, and depending on the type, they measure between five to thirty-six centimetres. Since seahorses are weak, they entangle their tails around plants, so they don’t get carried away by currents. If there isn’t another seahorse of the same kind in a tank, it goes in search of another species. Their life span is about four years. They have a dorsal fin in the middle of their bodies.  . They have bony rings around their bodies. The little mouth of a seahorse does not have any teeth. They swim slowly with their prehensile and coiled tail. A seahorse has crested gills, and the colour varies with the different types. They can also camouflage themselves to protect themselves from prey.
