Turbo marmoratus, known as the green turban, the marbled turban or great green turban, is a large species of marine gastropod with a thick calcareous operculum in the family Turbinidae, the turban snails. [1]

The shells of these large sea snails have a very thick layer of nacre; this species has been commercially fished as a source of mother of pearl.


These large snails live in tropical reefs in the Indian Ocean (off Tanzania, Madagascar, Aldabra and the Mascarene Basin) and tropical western Pacific oceans; also off Queensland, Australia. They are nocturnal and feed on algae.[1]


The distinctive shell grows to a length of 18 cm. It bears blunt tubercles, especially strong on the shoulders. Its colour is greyish-green. Its large, circular aperture has a golden, pearly shine.

Turbo marmoratus is the host of the ectoparasitic copepod Anthessius isamusi Uyeno & Nagasawa, 2012

The shell of marbled turbans is used as a source of nacre. The large opercula of Turbo marmoratus have been sold as paperweights or door stops.[2].
