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=0.00501 (0.00202 - 0.01242), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 2.8 ±0.2 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (K=0.089-0.32).
Fishing Vulnerability (Ref.
