The lined seahorse lives in the Atlantic Ocean as far north as Canada and as far south as the Caribbean, Mexico, and Venezuela. It swims in an erect position and uses its dorsal and pectoral fins for guidance while swimming. Lined seahorses feed mainly on minute crustaceans and brine shrimp, which they suck in through their snout.
