Sepiella ornata, or the ornate cuttlefish, is a species of cuttlefish^[3] first described by Sander Rang in 1837 based on a specimen caught in the Gulf of Guinea.^[4]

Description

Sepiella ornata has a mantle length of up to 100 millimeters,^[4] and a total body length of up to 100 centimeters.^[5] It has 10 to 14 suckers on each club (10 to 12 on males and 12 to 14 on females),^[3] and a series of spots along dorsal fins, described as either reddish^[4] or wine-colored.^[3]

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,^[4] including in Ghana,^[6] Namibia (though rarely),^[7]^[8] Mauritania, Senegal, the Gambia, Guinea-Bissau, and Guinea.^[9] It is demersal,^[10] with a depth range of 20 to 150 meters, though usually found below 30 meters,^[3] and it is most abundant below 50 meters.^[4] The species is found between 13 and 16 kilometers offshore.^[3] According to Djan, Finn, and Lazar, Sepiella ornata may prefer rocky over sandy sea beds,^[6] though Guerra, Gonzalez, Roeleveld, and Jereb write that it is mostly found on muddy or sandy mud bottoms.^[3]

Reproduction

Sepiella ornata has large eggs.^[11]

Interest to fisheries

According to Rocha and Cheikh, Sepiella ornata is of potential interest to fisheries,^[10] though Djan, Finn, and Lazar write that its small size means it is not economically valuable.^[6] As of 2014, it was mostly caught as bycatch in bottom trawls.^[3]
