Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 5 - 7; Anal soft rays: 4 - 6. Characterized by having escal morphology: escal bulb with small rounded, anteriorly to anteroventrally directed papilla on anterior midline and slightly larger dorsally to anterodorsally directed papilla on dorsal midline; simple and unpigmented papillae in specimens less than 98 mm, bifurcated papillae, forming shallow medial area that is darkly pigmented in specimens 98mm and larger; most specimens with 2 small unpigmented papillae placed bilaterally on dorsal surface of escal bulb near base of posterior escal appendage; compressed posterior appendage crescent shaped and approximately as long as escal bulb; darkly pigmented swollen basal part of posterior appendage in specimens 98mm and larger; presence of filaments on posterior appendage, pigmented in 159-mm specimens; teeth in lower jaw 31-286; teeth on vomer 4-10 (Ref. 86949).
Mesopelagic (Ref. 10524) and bathypelagic (Ref. 58302).
