Lambis truncata, common name the giant spider conch, is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. [1]
Subspecies of Lambis truncata include:
Lambis truncata truncata has a flat apex, while the apex of Lambis truncata sebae is more pointed.
Lambis truncata is the largest and heaviest of spider shells, up to 40 cm. [1] Lambis truncata is similar to Lambis lambis but with a more squarish outline. [1] Younger shells are creamy white; columella and lip usually mauve brown when older. [1]
The distribution of Lambis truncata includes the Indian Ocean off [1] Aldabra, Chagos, Madagascar, Mauritius, Tanzania; the Bay of Bengal and in the Pacific Ocean along the Philippines.
Lambis truncata lives on rubble and coarse sand in shallow water. [1]
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may generally refer to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.
Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus Strombus was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.
The operculum is a corneous or calcareous anatomical structure like a trapdoor that exists in many groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc.
The Stromboidea, originally named the Strombacea by Rafinesque in 1815, is a superfamily of medium-sized to very large sea snails in the clade Littorinimorpha.
