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.

[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] 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,[citation needed] Namibia (though rarely),[6][7] Mauritania, Senegal, the Gambia, Guinea-Bissau, and Guinea.

[3] According to Guerra, Gonzalez, Roeleveld, and Jereb it is mostly found on muddy or sandy mud bottoms.

[10] According to Rocha and Cheikh, Sepiella ornata is of potential interest to fisheries.
