Metamorphosed females of Chaenophryne differ from other genera of the Oneirodidae by the presence of blunt protuberances on the dorsal surface of the head, sphenotic spines absent (vs. protuberances absent and sphenotic spines present), opercle only slightly concave posteriorly (vs. opercle deeply notched posteriorly), pelvic bones triradiate to broadly expanded distally (vs. pelvic bones rod shaped, with or without slight distal expansions), bones, especially those closely associated with the external surface of the head, highly cancellous (vs. not cancellous in other ceratioids), and illicium pterygiophore long, 70–82% SL (vs. less than 50% SL) (Pietsch, 1974, 1975, 2009).
