Description

This black European slug was curled up, likely to protect itself from the disturbances I was making in the understory.

According to the experts (Burke 2013, Forsyth 2004), Arion ater and Arion rufus can only be separated by dissection and comparing genitalia. The black morph of Arion rufus is not uncommon.
