Species: L. lambis
Scientific name: Lambis lambis
Common name of this shell is the spider conch, a species of large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
The Spider Conch has a very large, robust and heavy shell. One of its most striking characteristics is its flared outer lip, ornamented by six hollow marginal digitations. These digitations present subtle differences in shape between genders in this species, as the three anteriormost digitations are short and posteriorly bent in male individuals, and longer and dorsally recurved in females.
This species is widespread in the Indo-West Pacific, including Aldabra, Kenya, Madagascar, Mauritius, Mozambique, the Persian Gulf and the Red Sea, Seychelles, Tanzania, Micronesia, eastern Melanesia, Taiwan, southern Japan and northern Australia.
The Spider Conch lives in mangrove areas, as well as reef flats and coral-rubble bottoms in shallow water from low tide levels to depths of 5m. It is usually found in association with red algae.
