Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail: The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Maxillipeds are appendages modified to function as mouthparts.

The western population was then split as the western long-tailed hermit, "P. longirostris", leading to the renaming
