The West African seahorse is a species of fish in the family Syngnathidae. It is found in the eastern central Atlantic Ocean off Angola, Benin, Ivory Coast, Gambia, Ghana, Guinea, Liberia, Nigeria, São Tomé and Príncipe, Senegal, and Sierra Leone, as well as the Canary Islands. Although there have been no records from Algeria since Guichenot said that the type was collected at Béjaïa in the 1850s, but the location given may be an error.
