Maturity: L m   ?   range ? - ? cm
Max length : 5.7 cm TL male/unsexed; (Ref. 34506 )

Short description Morphology | Morphometrics

Dorsal soft rays (total): 82-95; Anal soft rays : 56 - 60. M. nigeli differs from the other species of the genus by the following combination of characters: head long with elongate, pointed snout and almost straight jaw, skull length 6.0-7.0% TL, rostral fang strongly hooked with distal part in a neatly right angle to dorsal profile of skull, predorsal length 14.5-18.5% TL, anterior anal fin ray below dorsal fin ray nos. 15-21, and 5 lateral, subdermal spots of pigmentation (Ref. 34506 ).

Biology     Glossary (e.g. epibenthic)

Four "Discovery" specimens were taken in closing nets between 1510 and 3910 m depth, three of these 1500-2000 m, and one 23 m above the bottom. The "Vityaz" specimen was taken between 3000 m and the surface (Ref. 34506 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.2   ±0.5 se; based on size and trophs of closest relatives Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
