Seahorses feed on small crustaceans and larvae, hunting in an ambush style. They prefer vegetated habitats to open water because they are poor swimmers. Seahorses typically cling to seaweed or swim in pairs, and have a small dorsal fin that allows only vibrating movement. There are about 40 seahorse species within three genera, with four species found in the United States. Seahorses face threats from predators like crabs and rays as well as from human activities such as pollution, fishing, and collection for medicinal or decorative purposes. Male seahorses are pregnant and give birth to live young after the female deposits eggs into their brood pouch.
