I was excited to find a Chlamys rubida, or Smooth Pink Scallop, growing on the dock at the marina.The shell looks softened, maybe by a sponge. It was a few inches underwater at high tide, and almost 3" across.

Description from Wikipedia

Bivalvia is a class of marine and freshwater molluscs with laterally compressed bodies enclosed by a shell in two hinged parts. Bivalves include clams, oysters, mussels, scallops, and numerous other families of shells. The majority are filter feeders and have no head or radula. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment on the seabed, where they are safe from predation. Others lie on the sea...
