Reader submitted photo of slugs mating by Rodney Brunlinger. I found this absolutely wonderful blog post about the mating habits of our banana slugs to go with it. Here’s a small excerpt but you really should read the whole thing.
…slug-sex begins with head-waving and gentle biting of the other slug’s genital opening. Once they get to the Big Deed, the slugs both insert their penises into the other’s genital opening (remember, both are on the right side of their head) and go at it for hours and hours. And hours and hours and hours. And then…sometimes…one or both slugs will CHEW OFF THE OTHER’S PENIS. Yep, they rasp with their radula until the penis comes off. Then they slurp down the penis like spaghetti.
I learn something new everyday. Thanks, Rodney.
