Shells of Aspa marginata can reach a size of 20–40 millimetres (0.79–1.57 in).^[3] These shells are quite thick, beige in color, with a smooth surface, a deep siphonal canal and a short spire.

This marine species occurs in Western Africa, Senegal and Canary Islands.^[3][2]

This genus is known in the fossil records from the Miocene of Italy and France to the Quaternary of Namibia and Spain (age range: from 15.97 to 0.781 million years ago).^[4]

The fossilized shells have been valued by humans and Neanderthals.^[5]
