Morphology and Anatomy:

Because of their rather similar morphology and the inadequate descriptions of many nominal species, it is practically impossible to make a detailed comparison among them. Some authors prefer to characterize these parasites according to their host groups or geographic regions.

A range of marine habitats. For example, Cucullanus austropacificus and C. gymnothoracis are described from fish inhabiting tropical reefs of the Indo-Pacific while C.  incognitus is described from a deep-water fish  occurring near the Chesterfield Islands and New Caledonia of the southwest Pacific Ocean (Moravec and Justine, 2018).
