The raccoon butterflyfish, also known as the lunula (Chaetodon lunula), is a species in the butterflyfish family (Chaetodontidae) with distinctive, memorable coloration. It lives in the warm waters of the Pacific and Indian Oceans. The name comes from the unique black striped pattern around the eyes, which looks like a raccoon mask.
