Solar Powered Giant ClamsPosted on Wednesday, April 27th, 2011 at 10:31 am by ReefTools
Giant clams start out like all other clams, as a small larvae floating in the ocean. They begin growing by using the food they obtain from filtering. But at some point, they pick up small algae called zooxanthellae that and a symbiotic relationship which allows the clam to be solar powered. As it continues to filter feed, the giant clam now has two fuel sources. This extra fuel source can grow to an absolutely massive size. Some giant clams can actually grow to more than 4 feet across, and weigh upwards of 500 lbs. Now, lately, the numbers of giant clams has been declining. One solution to this problem, is setting up giant clam farms, which in turn may help wild clam populations to rebound.
