I can understand that, but the one's that I'm finding live in mud, plain old
freshwater mud in a drainage ditch that is maybe connected to the
Mississippi River through the water-table. This site is only about 1/2 mile
from the main channel of the mighty Mississippi but there is a BIG Levee
separating the land from the River.
Evidently, these mollusks can take heat, dessication, and have an extremely
strong survival capability since there habitat sometimes is damp mud only!
To my experience, most mussels/clams lead a strictly aquatic life and
couldn't survive the habitat where I've found these samples, at least, not
to my limited knowledge.
Keep the ideas flowing, nanfa's!

> Not all mussels live in flowing water, I.E. the Pond Mussel and can
sometimes prefer the sand muck to a rockier substrate...many are/were found
in lakes. The Great Lakes at one time had a nice fauna of mussels. There
are several species with the name washboard in them..they are rigded
laterally, like a washboard. There is published data about the amount of
volume zebra and quagga mussels filter especially up here in the great
lakes...quagga is a much bigger problem than the zebra now here. Asian clams
though dont seem to be too much of a competition problem because they do
like sandy substrates as opposed to most native mussels like a rocky gravely
substrate.
