Overview
The true giant clam inhabits shallow Indo-Pacific reef environments, including lagoons and sandy reef substrates. Its heavy shell has deep radial folds. Above the shell, the exposed mantle is often olive-green or yellowish-brown, marked with small blue-green rings that can be especially conspicuous toward its edges.
Adults remain fixed in place. They filter microscopic food from seawater while also receiving nutrition from algae living within their tissues. Reproduction releases eggs and sperm into the water; the resulting larvae swim and feed before settling onto a suitable substrate, beginning the sedentary adult phase of the life cycle.
