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.
I found another one! This time bigger, fewer edge chips, and with both halves! Also in sea pork (tunicate). Dpom's going to clean it up, so stay tuned for an update photo.
According to Rebecca, this snail is only found embedded in the center of tunicates, in this case sea pork. Very thin shell. The second shell shows the other side after we cleaned off the tunicate.
Found embedded in sea pork wash-ashore. Paper thin, about an inch long. Heavy nacre on the interior. Exterior was covered by the sea pork.
