Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 6 - 7; Afterflossenweichstrahlen: 5 - 6. Metamorphosed females distinguished by the following characteristics: have filaments on the dorsal surface of head just behind the base of the illicium; length of illicium 168-198% SL; presence of short filaments on base of illicium; escal bulb gradually tapering into a conical, spinulose darkly pigmented distal prolongation, length 12-28% SL; escal bulb and distal prolongation bearing low unpigmented papillae; short filaments present on distal prolongation, absent on base of escal bulb; absence of posterior pair of close set illicial appendage; long dentary teeth (longest tooth 3.4-7.1% SL), three or four longitudinal series in posterior part of jaw; short rays of caudal fin (27.5-35% SL) (Ref. 86949).

Estimates based on models

Preferred temperature (Ref. 123201): 6.5 - 8.3, mean 7.8 °C (based on 9 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100).
