Working at the computer lab, new knowledge, great discoveries.

"Banana slugs are hermaphrodites, which means that they can act as both males and females at the same time. When they mate, they insert their penises into eachother at the same time. The unusual thing  is that sometimes, but not always, when they finish mating one slug will chew the penis completely off the other, a process called Apophallation. Sometimes it happens that both slugs engage in chewing so that at the end of the mating encounter, both slugs are penis-less."


This is a slug penis. This particular slug was injected with the peptide hormone APGWamide. This hormone causes erections within minutes.
