After a brief introduction to proper use of seines and D-nets, the class broke into groups and hit the creek:
We had the class hit both pools and riffles for maximum diversity. When each group had a good, representative sample of the fish and inverts from their area, we gathered and went through them all.
First some inverts:
Water Strider (Gerridae)
Water Scorpion! (Nepidae)
Then some herps, where the baggies come in handy - for passing around and viewing all angles. Of course we only kept them in the baggie for a short time, so you don't have to worry about the herp's welfare.
Larval Salamander (Gyrinophilus)
And then, the fish!

Behold, the Fish Bowl!
Look into the bowl - what will you see?
We let all but a few representatives of the smaller species go. Those lucky few that were chosen get to live in the aquarium in our lab for a time. They take readily to fish flakes.

Hopefully, I'll be getting some better photos in the near future. I just need practice shooting through glass.
I'm a big fan of darters, I always love finding these: Fantail Darter, Etheostoma flabellare. The first dorsal fin has low knobs on it, which serve as egg mimics when resting in the nest - eggs are laid to the undersides of rocks.

That water scorpion is huge!
