Class Bivalvia
Bivalves (clams, oysters, mussels) possess a shell composed of two hinged valves. They lack a distinct head and radula. Bivalves are universally filter feeders, filtering vast quantities of water through their gills to capture plankton and suspended detritus. This continuous, monotonous activity contributes to their noted stoicism and ability to form massive, silent shell middens over millennia.
Class Cephalopoda
