The colorful mantle of the giant clam Tridacna squamosa expresses a homolog of electrogenic sodium: Bicarbonate cotransporter 2 that mediates the supply of inorganic carbon to photosynthesizing symbionts.

Giant clams live in symbiosis with phototrophic dinoflagellates, which reside Top extracellularly inside zooxanthellal tubules located mainly in the colourful and extensible outer mantle.As symbiotic dinoflagellates have no access to the ambient seawater, they need to obtain inorganic carbon (Ci) from the host for photosynthesis during illumination
