Estimates based on models
Preferred temperature (Ref.
123201): 23.5 - 24.6, mean 23.8 °C (based on 14 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
