Tridacna maxima (Röding, 1798)

Scattered about on reef sites were a few Tridacna maxima, one of the smaller members of the giant clam family (although still typically larger than T. crocea). These live embedded in the reef and were not especially common, probably also having been fished extensively for food in years past. This species can usually be easily recognized by the row of black dots just in from the margins of the mantle.

A young one with still fairly large flutes (or scales).

I've gone back and forth on the one below. I guess by the black dots along the margin, it looks most like Tridacna maxima.
