Description

Size 28-30mm, with slightly elevated spires. Pale brown colour with faint brown or yellow trans-spiral lines. Commonly crawls on sandy bottom in meso littoral zone.[2]

Shells of Paratectonatica tigrina can reach a size of 20–40 millimetres (0.79–1.57 in).[3] These shells are pear-shaped and quite thick, with the tip of the spiral sticking out. They have a whitish or pale brown surface with small dark brown or black spots. Operculum is white and quite smooth, usually with yellow and gray patches. The foot of the mollusk is whitish, almost translucent, plain and large.[4]

Distribution

This species occurs in the Red Sea and in the Indian Ocean off Madagascar. They are also commonly found along the Southeast Indian coast and the Konkan coast up to Kerala.[5]

Paratectonatica tigrina can be found in the Eastern Africa, Southeastern Asia and Australia.[3][6]

Human uses

In some countries (mainly Indonesia and Japan) these sea snails are collected for food and the shells are traded.[4]
