Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 19.7 - 25.4, mean 22.9 (based on 8 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00902 - 0.02916), b=3.05 (2.90 - 3.20), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (45 of 100) .
