Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 2; членистые (мягкие) лучи спинного плавника (общее число) : 140 - 141. Head large; eyes also large; snout short, narrow, bluntly acute, with a small bifid scute at its tip. Head completely scaled except for underside of snout. Body tapering to a point posteriorly from behind the origin of the first dorsal fin base. Pyloric caeca 20. Spinules on scales broad, shield-shaped. Overall color is brownish to swarthy; trunk bluish to violet; fins blackish; mouth and gill cavities gray to blackish.

биология     глоссарий (например epibenthic)

Specimens from northwestern Africa feed primarily on faunal organisms, especially polychaetes (90% of contents) and a variety of small crustaceans. Smaller individuals (30-40 mm head length) feed mostly on epibenthic organisms, especially the copepod Aetidopsis carinata (Ref. 6219).

Estimates based on models

Preferred temperature (Ref. 115969): 6.2 - 8.7, mean 6.8 (based on 8 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.31 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179):  низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
