Ecology of Tridacna maxima

Main Ref.	Bernard, F.R., Y.Y. Cai and B. Morton, 1993
Remarks	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).
