Summary

Description

The shell is a tall, slender, sharply pointed cone. There may be as many as 20 whorls, each bearing spiral ridges and grooves. The shell is brownish- yellow to white in colour and often with a lilac tinge on the base, and grows up to 3 cm in length and 1 cm wide. The shell aperture is small and squarish. The operculum is edged with pinnate bristles. The foot of the snail is small, the flesh buff with dark spots and streaks and there is white markings on the tentacles, siphon and foot.

Recorded distribution in Britain and Ireland

Common around Britain and Ireland but not recorded from the south east coast of England.

Global distribution

Found in the Mediterranean, and from Norway to north Africa.

Habitat

Abundant on muddy sediments in shallow water, more or less buried but maintaining contact with the water. This species is slow moving and sits on the seabed filtering seawater for particles of food. It may be gregarious, occurring in large numbers. It can be found down to 200 m.
