Seahorses may just be one of the ocean's most unique fish. Although their appearance would suggest otherwise, seahorses are members of the fish family. They have a swim bladder and breathe through gills. They have fins and scales like other fish, too. 

A seahorse's pectoral fins, located just behind the head on both sides, and anal fin, located on its front just before the tail, are used for steering and keeping the seahorse upright in the water.

Its dorsal fin, located on its back, is used for propulsion, or moving through the water. This fin moves 30-70 per second to propel a seahorse through the water! Its swim bladder moves the seahorse up or down.

Seahorses swim in an upright position. Sometimes they move in pairs, holding tails.  

Though they have few natural predators other than crabs, seahorses are under constant threat by humans. Seahorses are used in Chinese medicines, are sold as pets, and are dried and sold as souvenirs.

The seahorse's Latin name is hippocampus. Hippo is Latin for "horse" and campus means "sea monster." It is named for the fact that its head, with its long snout, resembles a horse's head.

The snout is used for eating and  rooting around in sea plants for food. A seahorse sucks food through its snout. It doesn't have teeth or a stomach so a seahorse must eat almost constantly.

Besides its extraordinary appearance, one of the most unique facts about the seahorse is that the male carries the young. After mating, the female releases eggs into the male's brood pouch where they stay until the babies, called fry, are ready to be born 2-4 weeks later.

With more than 40 known species, seahorses are found in a wide variety of colors. Like a chameleon, they can change color to blend in to their surroundings. They may also change colors during courtship.
