Fascinating stuff, Cali, as always. :thumbsup:

Makes me wonder, though. Do you regularly do google searches on "detachable spider penises"?

Actually, I found this stuff whilst searching for something completely different. This process is starting to happen so often, that I've taken to calling it the Monty Python Teleology Slip. Off I go, purposefully seeking papers on one subject and suddenly, my Google Scholar search drops something completely different, and compelling, in my lap, leading to a temporary, but very educational, tangential diversion.

See? I didn't even "design" this thread, in the strict teleological sense. Something interesting cropped up out of the blue, and I thought "oh it'll go nicely here".
