This species is widespread in the Indo-West Pacific, including Aldabra, Kenya, Madagascar, Mauritius, Mozambique, the Persian Gulf and the Red Sea, Seychelles, Tanzania, maritime Southeast Asia, Micronesia, eastern Melanesia, Taiwan, southern Japan and northern Australia.
The maximum shell length for this species is up to 29 cm, and average length stands for 18 cm. Lambis lambis 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. The color of the shell is highly variable, being white or cream externally and often presenting brown, purplish or bluish black patches. The interior is glazed and may be pink, orange or purple.
