Short description
Identification keys | Morphology | Morphometrics
Vertebrae: 200. This species is distinguished by the following characters: with a minute pectoral fin, many filamentous cirri on anterior nostril rim; a very small gill opening (3.8% HL); body depth 4.7 times in HL, 77 in TL; dorsal-fin origin in anterior, 1/3 of trunk, 1.7 times HL behind the gill opening; predorsal length 6.0 in TL; head relatively is short, 16.2 in TL; trunk 3.1 in TL; tail long, 1.6 in TL; pectoral fin a minute flap with some visible rays; total vertebrae 200; VF 30-78-200l; cephalic lateral-line pores 11; predorsal pores 33; preanal pores 78; total pores 169, the last 1.5 times HL before tail tip (Ref. 106137).
This species was collected by fishery otter trawl in the same haul with many macrourids, ophidiids, deep-sea shrimps and other demersal fishes that would suggest a benthic habit (Ref. 106137).
