Ok, ok, I know this doesn't stand out, but I adore the nature and structure of shark skin. Slimily hydrodynamic with the grain of their scales, flesh-shreddingly coarse against. Shot in the tunnel under the tank at the Mall of America's SeaLife aquarium. The faux twilight, the convex refraction, and the biological grey colored this beautifully, a tanked hunter. I know saw fishes are a different family, but they were in there with them, and they all have double-penises, haha.
