Before I make a late night run to the grocery store. I'll be back shortly. But my favorite part is:
The tail of the long-tailed slug (Ibycus rachelae) is three-times the length of its head, allowing it to curl up to sleep. More unusually, when it mates the slug fires a so-called "love dart" made of calcium carbonate that injects a hormone into its prospective partner to increase the chances of reproduction.
We have entered a brave new evolutionary world we have. Sex Weaponry FTW!
