 Like corals, giant clams live in partnership with tiny plantlike algae (called zooxanthellae) that live inside the clams' tissues. And as with corals, the arrangement helps both creatures. The algae gain protection from grazing animals; the clams grow large with the benefit of food produced by the algae. http://www.montereybayaquarium.org/animal-guide/invertebrates/giant-clam
