They live within seaweed beds under warves, on reefs, boat moorings etc. Sea horses range in size from two inches (50mm)(the Dwarf sea horse)in length to about 1 foot (300mm), although most are around 6 inches(150mm)in length.

They latch onto seaweed and other small obstacles within their enviroment with their tails and use a small fin on their backs for swimming.

Seahorses love to eat small brine shrimp.

The most unusual seahorse lives in Australian waters, This seahorse has seaweed like camouflage all over its body, making it almost invisable.

They normally go through a series of courtship rituals that lasts for a few days before they mate. This ritual involves such things as changing color and side by side synchronised swimming.

The female produces hundreds of pinkish coloured eggs. These eggs vary from between .5 to 1.5 millimeters in size, depending on the species. The female then deposits them into a pouch on the males abdomen where he fertilizes them.

These eggs are held inside the male's body until they hatch. He is pregnant for about 40 to 50 days. The sea horse is the only animal in which the male is pregnant.
