Aspa marginata is the name of a snail from the family of frog snails and the only recent representative of the genus Aspa , which is distributed in the eastern Atlantic Ocean on the coast of Africa .

features

The mostly beige snail shell of Aspa marginata has a very short thread with very short and wide varices. It is highly inflated and has an almost smooth surface with no knots. These characteristics are unique in the family, so that the species can be easily recognized by them. It has a rather long, deep siphonal channel. In adult snails, the house is about 2 to 4 cm long.

Distribution, Habitat, and Fossil Findings

Aspa marginata is, besides Bursa scrobilator, the only species of frog snail found in the eastern Atlantic , and it is quite rare. It can be found on the coast of West Africa and the Canary Islands at depths of 6 to 60 m. Snail shells have been found in rock layers since the Pliocene .

Way of life

Practically nothing is known about the living snail Aspa marginata , so that only guesses can be made with regard to its way of life. Other species in the family predatory feed on polychaetes and echinoderms, among others .
