The banana slug is the second largest slug in the world, growing up to 10 inches in length. On average they range between 6-8 inches, with a life span of 1-7 years (Harper 1988). Their coloring is sometimes bright yellow, occasionally with black spots, or solid greenish. Individual slugs will change colors with alterations in food consumption, light exposure, and moisture levels. Color may also indicate whether a slug is healthy, injured, or what age they are (Harper 1988). Their coloring allows them to camouflage with leaves and other debris on the forest floor.

They are continuously distributed throughout this region where they seek shelter beneath coastal redwoods and detritus. Within the primarily Mediterranean and Marine West Coast biomes, they remain active most of the year. Banana slugs show arboreal tendencies but are commonly encountered on the ground or within creek banks and tree roots during the dry summer months (Ingram & Lotz 1950).

These two slugs belong to the Subclass Pulmonata due to their pnuemostones. A pnuemostone is an opening which leads to a small lung. This is one way which the slug can breathe. The pnuemostone is also used in excreting waste. The slug can also breathe through its skin so long as the skin remains moist for gas exchange to take place.
