A banana slug, Ariolimax columbianus, in a Pacific Northwest rainforest, Washington. Banana slugs are decomposers and play an important role in their ecosystem. 

Slugs eat the dead matter of plants, moss, mushroom spores, and animal droppings.

A Pacific Banana Slug eating bright purple flower petals. Slugs don't have teeth or tongues. They have a special organ called a radula that has thousands of tiny protrusions that help them grind up their food.

Named for their resemblance to a banana, the banana slug is found in humid areas where they aren't in danger of drying out.
