Just picked up this guy today. This is my first clam (besides hitchhiker). It was labeled as a Dersara but looks more like a Crocea or Maxima to me. I'm not expert on clam identification, I just really liked the pattern on this and gave it the go. Just added today, not fully open yet.

Its also not a derasa, so I think we're down to its a clam and is probably a crocea or a squamosa.
