Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00149 - 0.01114), b=3.16 (2.92 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.7 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 非常低的, 最小族群倍增时间超过14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
