East African Slug
Polytoxon robustum (?)
Observed at Nakuru, Kenya, Africa. July 2014.
Large land snails lacking shells are known as slugs. Like snails they move along on a layer of mucus secreted by their 'stomach-foot'. This is the reason for the order name 'Gastropoda'. This restricts slug activity to times when the relative humidity is high. In moist cloud forests slugs and snails can forage by day, but in other environments they must come out of underground hiding only at night or during rain events. Several families of land snails have evolved this slug-like trait.
