Estimates based on models

Preferred temperature (Ref. 123201): 19.4 - 23.7, mean 21.7 °C (based on 40 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
