Here's a question... How do you tell the difference from the fingernail clams and the Asiatic clams (Corbicula sp)? Is there a difference in teeth? I was looking at some the other day that looked different than what I think of when I think Corbicula (smooth, two small teeth on either side of umbo), but sorta the same. Then I saw what were definately Corbicula (large specimens) way downstream where we took the kidos and they had much more developed teeth.

Of course the habitats were totally different. I was up in the wet ditches of sand and clay where I thought I'd found fingernail clams and the downstream section was fast water with rocks.
