Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00268 - 0.01234), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
