Clam larvae? under microscope - several days post hatch (DPH)

I found these larvae a couple nights ago while checking on the white spot anemone shrimp egg clutch during light out. It seems to be clam larvae. Notice the eyes on the shells. Some appears to be a lot larger than others so I think the hatching took place a couple days prior. The only mollusk I have for the last few months in the tank is a decent sized Electric Flame Scallop but its by itself. I believe its a female due to its current size. I read that it starts out as male and becomes female as it gets older. Average life for a flame scallop (closer related to file clams) is about 3 years in the wild. Check this out and let me know if you guys seen something like this before.

That's awesome. Where did you find them?

Clams living in the shallow reefs typically have eyes. Deeper water ones dont. They call it "simple" eyes. Eyes on all the species of Tridacna clams are on the rim of their mantles thus they can detect shadows and closes their mantles when we wave our hands across the tank over them.

Very cool video.
Thanks for sharing.
These are baby snails.
Look at the pair of moving testicles.
