Estimates based on models
Preferred temperature (Ref.
123201): 17.4 - 28.1, mean 25.8 °C (based on 757 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00335 - 0.01035), b=2.94 (2.78 - 3.10), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.

Trophic level (Ref.
69278): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
