Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2. Fully-scaled underside of head and lower jaw; snout long, length 44.5-51.4% HL, dorsal anterior surface upturned in lateral profile; area anterior to and below nostrils covered with scales between nostrils and suborbital ridge; light organ lacking obvious ventral dermal window; anterior of the anal fin dusky, pale posteriorly (Ref. 26363). Similar to a number of moderate- to long-snouted Caelorinchus species which lack distinguishing body or fin markings but may be differentiated from each other based on their body proportions, among other characters (Ref. 26363).
A benthic species found on the continental slope (Ref. 75154).
