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

Summary

Description

Emarginula fissura is a typical conical limpet shape with a white shell. The shell is up to 10 mm long and 8 mm high. The foot is shield shaped, broader towards the front. The apex of the shell curves over to the rear of the animal and there is a slit in the front edge that continues to the apex as a groove.

Recorded distribution in Britain and Ireland

On all suitable British and Irish coasts but absent fron the eastern English Channel and southern North Sea.
