परिपक्व अवधि: Lm ?, range 13 - 15 cm Max length : 50.0 cm SHL पुल्लिंग / अलिंग; (संदर्भ 117184); common length : 20.0 cm SHL पुल्लिंग / अलिंग; (संदर्भ 348)
The valves are thick, heavy and triangular in shape, often covered with reddish spots and obscured by encrustations. The mantle is a deep yellowgreen, irregularly mottled at the periphery and in the center.
Collected for food and shell, the latter commonly used in the shellcraft industry (Ref. 348). Maximum depth from Ref. 75831. In relatively shallow water, in lagoon, barrier and fringing reefs (Ref. 106851). Found in intertidal areas on corals (Ref. 75831). Tridacnids derive their nutrition from uptake of dissolved matter through their epidermis and from their symbiotic zooanthella Symbiodinium microadriaticum (Ref. 107098).

Broadcast spawners. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
