Distinguishing characteristics of metamorphosed female: relatively small esca, width about equal to length; conspicuous bulbous posteriorly oriented terminal escal papilla; absence of posterior and anterior escal appendages; escal pore at posterobasal margin of terminal papilla; teeth in lower jaw 25-65, upper jaw with 27-82 teeth; vomerine teeth 4-14 (Ref. 86949).
Found near or on continental shelf, old specimens probably benthic (Ref. 6939). Bentho-, meso- and bathypelagic (Ref. 58302).
