Giant Clam - tridacna gigas

Giant Clam - tridacna gigas

The giant clam gets only one chance to find a nice home. Once it fastens itself to a spot on a reef, there it sits for the rest of its life. These bottom-dwelling behemoths are the largest mollusks on Earth. They can be 47 inches long and weigh up to 400 pounds. Can grow 12 centimeters (almost 5 inches) per year. Average life span 20-100 years. Brilliant colors, fluorescent blue, with many iridescent blue spots especially around the mantel’s edges. This one is a muted green inside the mantle with a brighter green siphon on the right side. Diet nutrients produced by algae that the clam plays host to and lives in a photo symbiosis relationship. Also eats plankton. Location: Pacific Indian Ocean, Labuan Bajo Flores, Sebayur Island, Indonesia. September 2019. Cropped 3043 x 3077.
