Here's a northern copperhead. Shot behind nasty zoo glass in a weird mix of flourescent (UVB), tungsten (spot) and ambient light with an off-camera strobe.

Canon 20D, 100mm/2.8 macro, 1.4x, st-e2, 550EX, softbox.
It was initially a trash picture, but after some tinkering in postprocessing, I like it.
