Clam sticking out it's tongue???

[Delphinus]

He seems to be alright? :confused: Usually when I've noticed something amiss with a clam it doesn't take very long for my suspicions to be confirmed (e.g., last month I bought a crocea from a LFS .. after 3 days I suspected something was up .... 2 days after that it was gone. Very quick downward spiral with these guys!) This guy, most of the time he looks fine ... and it's been a week without any sign of decline (so far anyways .... touch wood!) I'm wondering if it's some kind of mechanism to clean out their gills if they get clogged or something.

I need Daniel Knop's email address ... that's what I need, I think he's the only one who might know. The post I've put up on RC ... it is just sitting there without anyone even giving me a courtesy "I don't know what that could be" kind of post ... :(

Oh well ... time is the ultimate indicator ....
