Wow, you got some good photos at Big Creek. It's cool to finally get to see what you saw there. Those saddled darters posed nicely for you. Great crayfish shot. Yep, that's a rainbow. Nice banded too. Most of these species were still in good color. I'm glad you found spawning stonerollers, duskystripe shiners, and Ozark minnows.

Sure was a pretty and interesting day for you!

Matt...
I'm glad someone dentally inclined is paying attention. The Ozarks offer a lot of unique species, several that have been hillbillified. It is a mystery to me.
Isaac...
I like all the preserved specimens in the jars of moonshine behind me. Appropriate. I'm glad the railroad tunnel did not cave in. Bats and mysterious gropings in the dark. I was glad to see the light at the end of the tunnel.
That day was pretty fun with flashy fins... but the next day provided additional nifty critters.

Wow, excellent and interesting photos throughout this post! After the greenside photo, the next 2 photos are of rainbows. You're correct on the next 4 photos after that being Ozarks. All of your darter photos are excellent, but I particularly like that first Ozark shot: great pose, nice camera angle, good color balance, and very sharp. Those 2 rainbow shots are great as well, as is the Ozark close-up. And it's nice to see that fawn again (I have no photos of it). Wow, what a fun day. Lots of good memories!

How can that be? They were in the same tiny creek, Steel Creek and the same tiny spot. What do you see that tells your eye they are a different species?
That was certainly a full day of mighty fine experiences.

Oh dear, Casper this is embarrassing.
rainbow = red in the anal fin, red tint to the caudal fin, orange lips, taller bodied, (and in parts of the Ozarks) red diamonds on scales
orangethroat = no red in the anal fin, clear caudal fin, blue lips, slender bodied, random black dots on scales

Well dang i see everything you speak of. Well since i don't have a fishy degree to defend i am not too embarrassed. I recall Mark Binkley learning me about Rainbows having red in their anal fins, i forgot about that. And that Rainbows kinda have rear facing tridents as their caudal spot. I see that often enough but not so much in this bull male though. Lots of variation to my eye when i am out and about.
Thanks for the assistance. My brain ain't young though and more info leaks out than goes in. That's ok as i mostly simply enjoy the experience, not the finely tuned skills that you have cultured.
I don't have Orangethroats around Chattanooga... but i netted some in central south Tennessee once and knew they were different. Long overdue to revisit those waters... Indian Creek and the Swans.
Rainbow = red in the anal fin, YES; red tint to the caudal fin, YES; orange lips, hum... kinda pale; taller bodied, um... OK; (and in parts of the Ozarks) red diamonds on scales. Are these red diamonds on the sides?
Orangethroat / Ozark = no red in the anal fin, YES; clear caudal fin, YES; blue lips, YES... i just thought he was as cold as i; slender bodied, SEEMINGLY; random black dots on scales. Are the random black blotches the black dots you speak of?

I'm glad Ben chimed in with such a good explanation. My answer wouldn't have been as helpful. I've seen enough of both species that I can usually tell them apart just by their general look - though the anal fin coloration was my traditional go-to ID character. But it gets more difficult for me if I move outside my local watershed. As you said, there is a lot of geographic variation in both species.

It was an honor to get to meet Dr. Roston and go snorkeling with him. That's a nice studfish. For those who haven't already seen it, Casper's DVD from his previous trip is a great watch.
Edit: Also, longnose darter at that site wouldn't be a range extension. Historically they were found very close by (less than 10 miles I think) in the White River. They just haven't been found in that area since the creation of Bull Shoals Lake around 60 years ago. It has been thought that the lake wiped out their habitat, but our unknown darter gave some hope that perhaps a small population still exists.

Thanks guys. When i edited in the eclectic selection of music, sometimes appropriately regional, it really complimented each day's adventures. I know several other members have copies of this DVD. However no one has taken me up on this particular offer. I was hoping to raise some additional funds for NANFA's good works.
