Giant Clam

Scientific name: Tridacna gigas

Giant clams, such as the one pictured, can reach a size of more than a meter in length and weigh more 200 kilograms. They can also live 100 years or more. What's really amazing is that these guys start life as tiny plankton.

Please note: Identification of fish, corals, etc. is a tricky business. It's entirely possible that I've incorrectly identified a photo I've taken. If you spot an error, please contact me so I can correct it and improve this resource.
