Overview

Comprehensive Description

Description

 Venus verrucosa is a bivalve mollusc with equally sized valves that can grow up to 7 cm. It is beige to brown in colour with a white internal surface. The warty venus is characterized by a series of 20 or more prominent concentric ridges intersected by radiating grooves resulting in wart-like spines. Also, the escutcheon, the depression behind the umbones that encompass the external ligament, is much wider and semi-eliptical on the left valve and marked with transverse brown stripes.

The warty venus, Venus verrucosa, is a species of saltwater clam. They are marine bivalve molluscs in the family Veneridae, sometimes known as the Venus clams.

Contents

Distribution

This species is found around the European coast and also the southern African coast, from the Namibian coast to Mozambique, subtidally to 155 m.[1]

Description

A fossilized shell of Venus verrucosa

This animal grows up to 60 mm in diameter. It has a bulky, oval shell with well defined concentric ridges. The shell edges are knobbly.[1]

Ecology

The warty venus burrows in mud and sand.
