Sinh học     Tự điển (thí dụ epibenthic)

Collected for food and for the shell trade. Aquaculture trials have been done in 1998 (Ref. 348). Maximum depth from Ref. 75831. Found in coral reef flats in shallow areas (Ref. 799), reef areas of lagoons (Ref. 97298) and in intertidal areas (Ref. 75831). Mixotrophic - filter feeds and photosynthesizes via its zooxanthellae (Ref. 105208). Tridacnids derive their nutrition from uptake of dissolved matter through their epidermis and from their symbiotic zooanthella Symbiodinium microadriaticum (Ref. 107098).

Life cycle and mating behavior Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Các trứng | Sự sinh sản | Ấu trùng

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