Project Description

Spiny pink scallop (Chlamys hastata) shell valves have sharp spines on their ridges, which you can see in the lower left corner of the photo.  Often these spines and ridges are hidden beneath sponges living on the shell valves.  The spiny pink scallop can grow to 3.7 inches (9.3 cm) across, and has a range from northern Alaska to southern California.
