Seahorse Exhibit Animals

Something's Fishy about this Family

Seahorses, sea dragons, pipehorses and pipefishes come in many shapes and sizes, but beneath the surface they’re all fish, with fused jaws and bony plates in place of the scales normally associated with fish.

Perhaps what most distinguishes seahorses from the rest of the animal kingdom is their unique life history—the males become pregnant and give birth. Seahorse fathers shelter their young in protective pouches, while sea dragon and pipefish fathers carry their young on spongy patches on the undersides of their tails.

No one knows how many seahorses actually exist. That’s because identifying seahorses is difficult. The smallest known species, discovered in 2008, is the half-inch-long Satomi’s pygmy seahorse; the largest species is the potbelly seahorse, which grows to about 14 inches long.
