Species of gastropod

Summary

Species of gastropod

Lyncina sulcidentata, common name the square-toothed cowry or groove-toothed cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.

Description

The shells of these quite uncommon cowries reach on average 27 - of length, with a minimum size of 20 mm and a maximum size of 75 mm. The dorsum surface is smooth and shiny, the basic color is reddish or brown-orange, with three wide blue-gray transversal bands. The base is white or light brown, with long teeth furrowing the base (hence the Latin name sulcidentata). The shell is quite similar to Lyncina schilderorum, Lyncina carneola and Lyncina ventriculus. In the living cowries mantle is brownish, with long bluish tree-shaped sensorial papillae. Mantle and foot are well developed, with external antennae. The lateral flaps of the mantle may hide completely the shell surface and may be quickly retracted into the shell.
