Aden Gulf torpedo
The Aden Gulf torpedo (''Torpedo adenensis'') is a poorly known species of electric ray in the family Torpedinidae, seemingly endemic to the eastern Gulf of Aden, near the coast of Yemen. Growing to long, this species has a nearly circular pectoral fin disc and a short, thick tail with two dorsal fins and a well-developed caudal fin. It is characterized by its reddish dorsal coloration, which in contrast to related species lacks any additional markings. The International Union for Conservation of Nature (IUCN) has assessed the Aden Gulf torpedo as Near Threatened, citing its extremely small range and the intensive shrimp trawling that occurs in the region.
==Taxonomy==
The first specimens of the Aden Gulf torpedo were collected in 1989 by the former Soviet research ship ''Stefanov'', and described as a new species by Marcelo R. de Carvalho, M.F.W. Stehmann, and L.G. Manilo in a 2002 issue of the scientific journal ''American Museum Novitates''. The specific epithet ''adenensis'' refers to only region where it has been found. The type specimen is a 41-cm-long adult male. This species belongs to the subgenus ''Torpedo'', but is unique in being plainly colored. It appears to be most closely related to the leopard torpedo (''T. panthera''), with which it shares a distinctive flap at the tips of the claspers.
