Do oysters grow their own shells?
Pacific oysters, for example, begin building their shells 14–18 hours after the egg is fertilized, laying down a shell made of aragonite. The larva continues life in the form of plankton for the next two to three weeks, feeding on microalgae, until it grows a foot to stick down to a hard surface.
Do oysters have mothers?
