SLUG: Don't tread on me

A spotted, eight-inch-long slug slimed its way onto my front walk the other day. Honestly, at first I thought it was a garter snake. I looked it up and learned that its Latin name is Limax maximus, and its common names are great grey slug or leopard slug. All are certainly appropriate monikers! This particular slug is a native of Europe, and the scientists who study such things seem especially intrigued by its means of reproduction, which is both acrobatic and hermaphroditic.
I snapped a photograph of the creature, with a door key next to it for scale, and posted it on social media. Leave it to my amusing friends to chime in: "Has it moved in? Looks like it's got its own key!" A taxman friend warned that if I tried to claim it as a dependent on my 1040, I could expect a knock on the door.
