Don't think it is Limax

Don't think it is Limax maximus as this slug does not show any sign of a keel. Also the mantle has two bands which I think is not present in L. maximus.

Wrong group - should be in 'Invertebrates'

Limacid even if keel doesn't show..

Both photos show the breathing-pore beautifully. It's toward the rear of the mantle, rather than in front of the mid-point, which rules out the Arion slugs. The right photo shows the fingerprint-like pattern of ridges on the mantle, which makes it Limacidae.
