I've moved this slug from the Arthropod category to the Other category for you. Snails and slugs are Mollusks. Arthropods have an exoskeleton and jointed limbs in at least one phase of their life. Think dragonfly, bee, crab, and ant.

I would say that is more a red slug than a black one, Arion rufus...

This is a color form of Arion Ater.Possibly brunneofasciata or bicolor.
There are many color forms,10 I think.
