European black slug
To find the most appropriate individual to answer your question, what county in Colorado do you live? Thanks! Ruth
This slug was found in arapahoe county very close to the Denver county line.
To find out if CSU is interested in this particular slug, I would recommend contact Dr. Whitney Cranshaw Whitney.Cranshaw@Colostate.edu. He would be the Professor at CSU that might be interested if this is the European Black Slug.
