# Clavatula

Clavatula is a genus of sea snails, marine gastropod mollusks in the family Clavatulidae.

## Description

In this genus, the shell is fusiform, with a well-produced spire. The whorls are coronated with tubercles or short spines at the suture;. The aperture is oval. The columellar lip is smooth, arcuate, and callous behind. The outer lip is thin and arcuated, with the anal sinus situated below the sutural coronal. The operculum is semioval with its nucleus about the middle, on the inner side.
The foot is large, short and obtuse behind. The eyes are placed externally near the extremity of the tentacles. The radula contains a small unicuspid central tooth with single sharp laterals (formula :1-1-1).
The species mostly inhabits the west coast of Africa.
