Yellow Banana Slug

Ecology
Banana slugs are detritivores, or decomposers. They process leaves, animal droppings, and dead plant material, and then recycle them into soil humus. They seem to have a fondness for mushrooms, and they spread seeds and spores when they eat, and excrete a nitrogen rich fertilizer. By consuming detritus (dead organic matter) slugs contribute to decomposition and the nutrient cycles and are an important aspect of the ecosystem.
Raccoons, garter snakes, ducks, geese and salamanders sometimes eat banana slugs; they roll the slugs in soil to bind the slime. Juvenile banana slugs are sometimes eaten by shrews or moles.
