Description

The West African seahorse is a seahorse of the family Syngnathidae reaching about 19 cm. The upright-swimming body has a horse-like head, a tube-shaped snout and a prehensile tail without a caudal fin, with which it holds onto seagrass and weeds; the body is encased in bony rings instead of scales. It sucks small zooplankton and shrimp-like crustaceans in through its snout. The species lives among seagrass, weeds and growth of shallow coastal water along the West African coast and around the Canary Islands. As in other seahorses the male broods the eggs in a pouch and 'gives birth' to live young. Through fishing for traditional medicine and the souvenir trade the species is assessed as Vulnerable (VU) and is listed on CITES Appendix II.
