T. crocea is the smallest of the giant clams. This species typically reaches a shell length of 4 to 6 inches. These should be considered a "high light" species.

T. crocea clams lack pronounced scales on the shells called "scutes" giving the clam a fairly smooth shell.

You can clearly see the white of new shell growth and see the gills exposed in the siphon opening.
