This macro-shot of an iridescent clam was taken in the Southern Red Sea, Marsa Alam, Egypt. These clams spend their lives embedded amongst stony corals, where they nest and grow. It took David some time to approach the clam, fearing it would sense his movements and snap shut!
Nikon D7100-105mm lens + Saga 10 diopters wet lens; 1/180 sec at f27; ISO 200; Isotta housing; 2xStrobes.
