Dissecting Arion ater in order to determine subspecies.
Currently subjects are anesthetized in 5% iso alcohol solution until unresponsive, euthanized in 91% iso alcohol, then dissected and photographed in water. Reproductive systems are preserved in ~80% iso alcohol after photographing. Isopropyl alcohol is used due to availability and cost.
