Chlamys rubida (Hinds 1845)

Here is a view of the right valve of the individual above. These animals usually sit on the bottom with the left valve up and the right valve down. The larger "wing" at the hinge projects anteriorly, and if the shell is agape the foot can be seen near the anterior end of the shell.
