Sepiella ornata, or the ornate cuttlefish, is a species of cuttlefish first described by Sander Rang in 1837 based on a specimen caught in the Gulf of Guinea.
Description
Sepiella ornata has a mantle length of up to 100 millimeters, and a total body length of up to 100 centimeters. It has 10 to 14 suckers on each club (10 to 12 on males and 12 to 14 on females), and a series of spots along dorsal fins, described as either reddish or wine-colored.
Distribution and habitat
Sepiella ornata is found in the east Atlantic ocean along the west coast of Africa, from Cape Blanco in Mauritania to Cape Frio in Namibia, including in Ghana, Namibia (though rarely), Mauritania, Senegal, the Gambia, Guinea-Bissau, and Guinea. It is demersal, with a depth range of 20 to 150 meters, though usually found below 30 meters, and it is most abundant below 50 meters. The species is found between 13 and 16 kilometers offshore. According to Djan, Finn, and Lazar, Sepiella ornata may prefer rocky over sandy sea beds, though Guerra, Gonzalez, Roeleveld, and Jereb write that it is mostly found on muddy or sandy mud bottoms.
Reproduction
Sepiella ornata has large eggs.
Interest to fisheries
According to Rocha and Cheikh, Sepiella ornata is of potential interest to fisheries, though Djan, Finn, and Lazar write that its small size means it is not economically valuable. As of 2014, it was mostly caught as bycatch in bottom trawls.
