Ok, this is just too cool. I've had this squamosa clam since September. I'm taking down the tank it was in so I moved my clams into my 75g on the weekend. I was just sitting in front of the 75g earlier tonight, when I saw something move inside the inhalant siphon of the squamosa clam (mantle fully expanded, this guy is the size of a football

)
So I grabbed my camera. Had a little trouble getting focus, but here's what I was able to grab tonight, then my camera's battery died. I'll have to try again tomorrow to get some better shots. So, without any further ado ....
Pictures of the clam from when I first got it home can be seen in this thread:
