Description
Shell of Gibberulus gibberulus (Index Testarum Conchyliorum (1742) of Niccolò Gualtieri)

The adult shell size varies between 30 mm and 70 mm. The smooth shell is gibbous. The spire is occasionally varicose. The body whorl is grooved at the base. The columella is smooth. The interior of the aperture is radiately striate. The shell is mottled and hieroglyphically marked with yellowish brown and white. The markings are often arranged in a few or numerous interrupted revolving bands. The aperture is tinged violaceous, scarlet or dark purplish brown.[2]

Distribution

This species occurs in the Red Sea and in the Indian Ocean off Aldabra, Chagos, Kenya, Madagascar, Mauritius, Mozambique, the Seychelles and Tanzania; in the Pacific Ocean off Australia (Northern Territory, Queensland and Western Australia).
