Sometimes, I get weird emails from my dad:
"Bizarre little marsupials [opossums] , they are said to mate through the nose (of
the female). The male presumably has a forked penis and the only
visible paired openings on the female are nostrils. The female is also
known to lick the interior of her pouch and the fur between it and the
vagina before birth. Folks say that she is then blowing the embryos out
of her nose and into the pouch. Zoologists figger that her tongue
freshens up the path that the centimeter long, blind, glorified embryos
crawl up to reach the pouch. There they will hang on to one of 13 teats
and remain tethered for 2-3 months. The forked penis, zoologists
claim, is better suited for interaction with the female's paired uteri
(from which bit they are named Didelphis (double wombed) virginiana."
well, that's kind of gross, but he's a doctor, and when you think about this biologically, it becomes interesting, first, what mental or environmental conditions would have made this an advantageous method, and second, how could it have become so advantageous a method as to become ingrained behavior. There must be something olfactory promoting this.
There are alot of skunks on UConn's campus, including one with switched colors, black stripe on white. There's a note in my dorm not to put food in the garbage public garbage cans, because the maid found a skunk in the bathroom.
