The hermit crab in this picture is an example of a detritovore. A detritovore is a consumer that derives its nutrients and energy from nonliving organic material such as corpses, fallen plant material, and wastes of organisms. Detritovores are also commonly known as “decomposers”. Hermit crabs, belonging to the superfamily Paguroidea, are omviorous detritovores. Because they are detritovores, hermit crabs learn to avoid toxins through learned food aversion they would normally encounter.
