Tridacna gigas is truly the Giant Clam of legend. This species grows rapidly to over 4 feet in length and has been recorded to weigh more than 700lbs!  They are typically found in shallow lagoons and reef flats up to a depth of 60 feet.  As juveniles they will attach to the substrate using their byssal organ which secretes sticky threads.  In time this organ atrophies, and the large size of the animal helps keeps it in place. ORA sells juveniles of this species, which are a golden color highlighted by teal and blue spots on the mantle.
