prev Glorious mantle of the giant clam (Tridacna gigas) which have largely been destroyed from the reefs except in Papua. The iridiscence is produced by zooxanthellae (dinoflagellate algae) within the mantle tissue.The opening in the bottom of the photo is called the vent and the one at the top is the siphon. There is great variability among individuals in the amount of food gained via the algae vs. the filter- feeding. (Cape Kri) next
