Estimates based on models
Preferred temperature (Ref.
123201): 25.3 - 29.2, mean 28.6 °C (based on 985 cells).
Phylogenetic diversity index (Ref.

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00470 - 0.02030), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
