Cool stuff.
I used to go caving all the time last year, and in this fairly large cave there was a big river running through it. Back near the end (about 2 hours or more into the cave) you could find all sorts of cool creatures in the river. All of them were albino, because the cave is pitch black, and all of them were completely blind. There were salamanders, little fish, and all sorts of other things. If you ever get the chance to go caving, try it out, it's a surreal experience.
Dunno why that post reminded me of that. Cool pic.
