Thanks for taking a look at the mussels.
Yeah, the TN and OH greensides are completely different. It seems like the
TN fish have blotched "U" or "V" bands on the sides, where as the OH fish
have parallel lines.
One of the students in my department is working on greensides. Specifically
with E. b. pholidotum and whether it deserves subspecies status or not...
To which I replied "Well the fish in the Allegheny look like the fish in
Duck and the fish in the Tennessee mainstem look like their own thing, while
the fish in the Holston and Clinch look like fish from the Scioto, which
sorta resemble the fish in the Lake Erie tribs, but without that stunning
red band in the dorsal, and I've seen pictures of fish from the Ozarks that
look like fish in Michigan, but that might just be me." lol
Really... I'm more into "that looks pretty" rather than how many lateral
scales are on a fish, but someone should do the work I guess ;)

big indication of this as I have a Monkeyface Q. metenevra and Mapleleaf out
right now. The direction and length are what I'm lookiung at specically.
Also posteior to the umbo see how the shell sort of extends and cureves down
and away from it, that really doesn't occur in metevra's it just is a
straight down with the shape of the inflation. Also looks like you have
some pustules on your beak sculpture. Don't have that monkey profile
either. Finally another big one, the cardinal teeth are very different and
this screams quadrula.

snorkeling this year, although they are no longer considered tippecanoe's.
Wow I can't get over how different I think coloration in Ohio greensides is
than TN greensides too.

impressive. Slowly but surely I am working on getting more digital photos of
shells from the Duck and Clinch and Green Rivers and fish pictures from the
TN drainage online.
