Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Calliostoma zizyphinum has a regularly conical, straight sided shell, up to 3 cm high and 3 cm broad, with a sharp apex and a flat base. The shell has regular spiral grooves and ridges and up to 12-13 whorls. The shell is very 'clean' and can be yellowish, pale pink or violet with streaks and blotches of brown, red or purple. Occasionally, individuals are white. The body tissue is also colourful and may be flecked with purple, crimson, reddish brown and yellow. The foot has 4-5 pairs of epipodial tentacles.

Recorded distribution in Britain and Ireland

Common on all coasts of Britain and Ireland.

Global distribution

Widely distributed in north west Europe from northern Norway south to the Azores and throughout the Mediterranean.

Habitat

Calliostoma zizyphinum is found on seaweed covered rocky shores from extreme low water to 300 m depth in the sublittoral.
