The “False Spider Conch” is a bizarre spider conch endemic to Southeast Polynesia, characterised by the black tips on digits. It lives on sandy or coral rubble bottoms in shallow water around -10~30m depth, and is a herbivore feeding mainly on algae and other organic particles. A locally uncommon species, it is rather rare on the market due to its restricted range. It is usually well disguised with overgrowths in habitat and difficult to find. Like all spider conchs it has very strong foot and is capable of jumping action. Average shell length around 130mm, giants may exceed 150mm. Most similar to Lambis scorpius (Linnaeus, 1758) and Lambis indomaris Abbott, 1961, but is easily distinguished from them by the much less “wavy”, less curved digitation, and the black digit tips. – adapted from Chong Chen’s post
