Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.01087 - 0.02779), b=3.09 (2.96 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
