Short description Μορφολογία
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).
Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae
Becomes simultaneous hermaphrodite in its later years. Spawning is seasonal, based on its northern and southern limits of distribution (Ref. 100714).
