Lined Seahorse Hippocampus erectus Perry, 1810    Synonyms: Northern Seahorse, Spotted Seahorse.
Kingdom Animalia   >   Phylum Chordata   >   Class Actinopterygii   >   Order Gasterosteiformes   >   Family Syngnathidae   >   Genus Hippocampus   

Status:

The Lined Seahorse is found in the Atlantic Ocean from Nova Scotia to the Caribbean and northernmost South America. The Lined Seahorse is apparently declining throughout its range due to coastal development, pollution, the aquarium trade, and use in Chinese medicine.

Where to find:

Although mainly marine, the Lined Seahorse also inhabits, in summer, shallow-water grassbeds, especially of American eelgrass, in the Chesapeake Bay. This fish is most commonly found from the lower- to mid-bay, but in summers that are drier and saltier than usual, it may move as far north as the Chesapeake Bay Bridge. In winter, it inhabits somewhat deeper channels (White, 1989).

Relationships:

With its prehensile tail wrapped around a blade of seagrass, which serves as a "holdfast," the Lined Seahorse feeds on a variety of tiny organisms, including crustaceans, mollusks, and zooplankton. Predators include larger fish, seabirds, and sea turtles.

There are 27 records in the project database.
