Estimates based on models

Preferred temperature (Ref. 115969): 14 - 26.5, mean 18.7 (based on 131 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.27; tm=5).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (83 of 100).
