Estimates based on models

Preferred temperature (Ref. 115969): 20.2 - 24.6, mean 24.3 °C (based on 9 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00259 - 0.01937), b=3.00 (2.76 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.62 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Vulnerability (Ref. 59153): High vulnerability (64 of 100) .

Price category (Ref. 80766): Medium.
