Seahorses can be found in the warm, shallow tropical ocean waters.  Seahorses get their name because their head looks like a horses head.  Most seahorses grow to be about 6 inches long, but the Pacific seahorse grows to be about 12 inches long.  The seahorse eats small animals by using its snout and sucking them into its mouth.  A seahorse is the only animal in which the male gives birth to the babies.  The female lays anywhere from only a couple dozen to hundreds of eggs in a small pouch on the male.  The male carries the eggs for 10-45 days depending on the kind and he then releases tiny living baby seahorses which are about three-eights of an inch long.   Seahorses are great for aquariums.
