Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 10; членистые (мягкие) лучи спинного плавника (общее число) : 16; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 7. This species is distinguished by the following set of characters: D X,16 with third dorsal spine longest; pectoral rays 18-20; lateral-line scales 40-44; greatest body depth 35.9-38.3% SL (2.6-2.8 in SL); predorsal formula 0/0+0/1+1; body without auxiliary scales; caudal fin lunate with filamentous extensions. Colouration: males with pink mostly horizontal vermiculate lines on the ventral and posterior part of the body and distal tips of caudal fin broadly pink-purple (Ref. 127477).
Collected in trawls at depths ranging from 110-119 m, and with two other species likely form mixed-species aggregations in the water column well above the bottom, feeding on plankton (Ref. 127477).

50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00618 - 0.02945), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
