Scientific Name:

Hippocampus algiricus

Species Authority:

Kaup, 1856

Common Name/s:

English

–

West African Seahorse

Synonym/s:

Hippocampus deanei Duméril 1857

Hippocampus kaupii Duméril 1870

Hippocampus punctulatus Kaup 1856

Taxonomic Notes:

Genetic research suggests that this species is part of the H. kuda complex and is very closely related to both H. kuda and H. reidi. Further research is needed.

Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2002
Assessor/s:	Project Seahorse
Reviewer/s:	Lafrance, P., Lourie, S., Marsden, D. & Vincent, A.C.J. (Syngnathid Red List Authority)
Justification: Very few data are available for this species. It is known primarily from museum specimens and no information on population status is available. Hong Kong reports imports of seahorses from west Africa (Gambia, Guinea, Nigeria, Senegal, and Togo) for traditional medicine. Only Hippocampus algiricus and H. hippocampus (possibly) are known to occur in this region (Lourie et al. 1999), so H. algiricus could potentially be involved in the trade. Appropriate data on biology and ecology, habitat, abundance, and distribution are not available. Further research is needed in order to assess the status of the species.

Geographic Range [top]

Range Description:	This species is known to occur in Atlantic coastal areas of West Africa.
Countries:	Native: Algeria; Angola; Benin; Côte d'Ivoire; Gambia; Ghana; Guinea; Liberia; Nigeria; Sao Tomé and Principe; Senegal; Sierra Leone
FAO Marine Fishing Areas:	Native: Atlantic – eastern central

Population Trend:	Unknown

Population Trend:

Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Habitat preferences are currently unknown (Lourie et al. 1999). This species may be particularly susceptible to decline. All seahorse species have vital parental care, and many species studied to date have high site fidelity (Perante et al. 2002, Vincent et al. in review), highly structured social behaviour (Vincent and Sadler 1995), and relatively sparse distributions (Lourie et al. 1999). The importance of life history parameters in determining response to exploitation has been demonstrated for a number of species (Jennings et al. 1998).
Systems:	Marine
