Banana slugs

Few slugs garner such attention as banana slugs. These large, often colorful slugs, are in the family Arionidae and the subfamily Ariolimacinae. This subfamily includes the following genera of banana slug, Ariolimax columbianus (Gould); A. dolichophallus; and A. californicus. Slugs in this subfamily have a keel along their back. They can often be found with a slime plug or caudal pore with a mucous plug.
