The clam absorbs nutrients produced by these bacteria rather than photosynthetically derived products and no longer has guts. [ 4 ] Little is known of the reproduction and life cycle of Calyptogena magnifica but examination of specimens brought up from the deep showed numerous large oocytes with yolks in various stages of development among the ...
The shell of the clam ranges from 15 centimeters (6 in) to over 20 centimeters (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 meter (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. [3]

When the piddock dies and leaves an empty tubular burrow, other marine life such as sea anemone, crabs and other molluscs may use the burrow. Some species of Pholadidae may reach up to 18 cm (7″). Their coloration is typically white, though through consumption of red tide algae some may develop a pink coloration.
