Size / Weight / Age

Maturity: L m   ?   range ? - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 34506 )

Short description Morphology | Morphometrics

Dorsal soft rays (total): 130-150; Anal soft rays : 110 - 130. M. boehlkei differs from all other species of the genus by the high number of anal fin rays (110-130 vs. 42-88) and by an obtuse angle between rostral fang and frontal profile of skull. It is further distinguished by the following combination of characters: head short, snout blunt, skull length4.2-5.2% TL, rostral fang with dorsal profile slightly concave, anal fin origin below dorsal fin rays number 7-13, pectoral fin 2-3% TL, lower jaw nearly straight, and 6 lateral, subdermal spots of pigmentation (Ref. 34506 ).

Biology     Glossary (e.g. epibenthic)

All specimens were taken in closing nets, one between 2500 and 3500 m with a bottom depth of 4563 m and the other specimens between 10-3- m above the bottom with soundings from 2960-5430 m (Ref. 34506 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 2.5 - 2.9, mean 2.7 °C (based on 105 cells). 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 ):  3.6   ±0.59 se; based on food items. Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
