Summary

Description

A slender razor shell up to 4 cm long. The shell can be thin and brittle and coloured white or cream, sometimes with dark markings. The outermost, relatively thin layer of shell (periostracum), if present is a glossy light yellow-brown or olive layer. Where the shell is joined the margin is almost straight, whereas the other edge is curved giving the shell a pod shape. The anterior end is rounded and the posterior end slightly truncate.

Recorded distribution in Britain and Ireland

Common off all British coasts

Global distribution

From Norway south to north west Africa and the Mediterranean.

Habitat

Phaxas pellucidus is found in fine mixed sands offshore to depths of around 100 m.
