Chín muồi sinh dục: Lm ?, range 16 - 20 cm Max length : 45.0 cm SHL con đực/không giới tính; (Tài liệu tham khảo 95990); common length : 30.0 cm SHL con đực/không giới tính; (Tài liệu tham khảo 348)
The species has an elongate shell with conspicuous fluted scales on its radial ridges. The valves are white and occasionally tinged with orange, and the mantle yellowish green.
Maximum depth from Ref. 87928. In eastern Polynesia, it is known to be restricted to deep water (Ref. 87928). Found in intertidal areas on corals (Ref. 75831). Abundant on outer reef slope (Ref. 2923). Also found in a lagoon (Ref. 87813), on sandy bottoms (Ref. 106695), rubble or in reef pockets (Ref. 2923). Unattached or weakly attached by byssus as an adult (Ref. 2923). Tridacnids derive their nutrition from uptake of dissolved matter through their epidermis and from their symbiotic zooanthella Symbiodinium microadriaticum (Ref. 107098).
