Chocolate Arion

Description:

Even though the most commonly used name for this species is 'Red Slug' I've chosen another synonym because of it's dark and 'chocolate-like' colour. This slug was approximately 12-13 cm in length when extended, and was dark brown. It's colour even appeared black while I was looking at it; but it came out as dark brown on my pics... (not sure if I should change my eyes or my phone-camera...) It sports a orange-reddish-striped fringe boarding it's sole, and dark tentacles. The respiratory pore is located toward the front of the mantle.

Habitat:

Found on edges of forest (predominantly coniferous, mainly spruce and fir tree) on one of Jura mountain passes, at some 1300m of altitude.

Notes:

In this species, the body colours range from brick-orange to black, but the sole fringe apparently remains orange-reddish.
