[8] Some clams expose their siphons as the surf is receding making them far easier to spot; this behavior is called ...

By day, the clams spread out their mantle so that the algae receive the sunlight they need to photosynthesize, whereas the colour pigments protect the clam against excessive light and UV radiation. Adult clams can get most (70–100%) of their nutrients from the algae and the rest from filter feeding. [12] When disturbed, the clam closes its shell.

The southern giant clam is a popular food item and aquarium species, and has therefore been hunted extensively throughout its natural habitat. [6] However, specimens traded today tend to be the result of aquaculture farms rather than wild-caught individuals, because the southern giant clam was one of the first clams to be bred commercially.
