生物學特性     字彙 (例如 epibenthic)

Nocturnally active; inhabits cracks and crevices during the day. Feeds on small mobile benthic organisms (Ref. 26966), by drifting up to its prey and swallowing it whole with a sideways snap of the large extensible mouth (Ref. 26966).

夜行活躍; 居住於裂縫與裂隙在白天期間。 吃小的移動底棲的生物 (參考文獻 26966), 藉由漂流達到它的獵物而且吞它全部向傍邊具有一個大可展開的嘴猛咬.(參考文獻 26966)

Estimates based on models

Preferred temperature (Ref. 123201): 16.6 - 23.2, mean 17.9 °C (based on 28 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
營養階層 (Ref. 69278):  3.5   ±0.5 se; based on diet studies.
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 5.14 [2.35, 16.48] mg/100g; Iron = 0.179 [0.071, 0.452] mg/100g; Protein = 17.9 [16.5, 19.3] %; Omega3 = 0.173 [0.062, 0.470] g/100g; Selenium = 8.29 [2.99, 22.55] μg/100g; VitaminA = 45.9 [8.0, 292.4] μg/100g; Zinc = 0.505 [0.291, 0.834] mg/100g (wet weight);
