Giant clams are on the CITES listing as endangers. Evidence of poaching is not what you want to find when you arrive at a remote uninhabited Manuae Atoll or is it Manuae Island. Either way these giant clams are probably 40+ years old and however old very slow growing. We must have just missed those harvesting the clams as there were still bits of flesh in the shells.
Here is a small coral head with a healthy unmolested population of giant clams. Each dark squiggle in the coral is a clam about 8-10" long or 25cm. There are alot of clams on the chunk of coral. Click on the image and zoom in.
More clams on a different coral head.
Close up of a clam. This clam is underwater and the camera is above the water. Pretty clear water I'd say.
