Summary

Description

Lucinella divaricata is a small bivalve, growing up to 1 cm in diameter. The shell often has oblique, wavy striations running across fine concentric grooves. The right valve has one cardinal tooth and single anterior and posterior lateral teeth. The left has two cardinals and two anterior and two posterior laterals. The outer surface of the shell is dirty-white to yellowish-white in colour.

Recorded distribution in Britain and Ireland
