Estimates based on models
Preferred temperature (Ref.
115969): 28.2 - 29.3, mean 28.8 °C (based on 366 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00421 - 0.01885), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (24 of 100) .
