It is white and fan-shaped with deep radiating ribs.
Known to be the largest bivalve mollusks that exist. Exploited for its meat and shell, this species has recently become nearly extinct within an important part of its range, due to over collecting. Trials of aquaculture under progress for the restocking of reefs and local farming (Ref. 348). Facultative planktotroph. It has an established symbiotic relationship with a dinoflagellate algae (zooxanthellae) which allows them to survive. It ingests the algae at an early stage and the latter propagates in the gut (Ref. 100719).
