Occurs in open water. Widely scattered when water is colder than 14.4°C; as water warms, descends into deeper, colder water.
出現於開放水域。 廣泛分散當水比 14.4 °C 更寒冷的時候; 當水溫暖, 進入比較深又比較寒冷的水之內下降。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00190 - 0.01097), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Generation time: 2.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (tmax=6).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
