Well, as I was dipping the squamosa in freshwater, I noticed something very interesting... pyramellids!

There were only 2 of them though, but after discovering that, I examined the carcass of the 3" maxima... on it's shell was a single pyramellid...
Interestingly enough, I never noticed them during the freshwater dips I had previously performed.
Wouldn't it take a lot more than a single pyramellid snail to kill 2 maximas? I could find no more than the 3 I pulled off them... and 2 were on the squamosa.
Well, at least I found them before they became a problem, but I'm skeptical that they were the cause of the clam deaths.
Here's a picture of the snails in question... they were too small to photograph so I slapped them on my scanner.
