Estimates based on models
Preferred temperature (Ref. 115969
): 26.6 - 29.1, mean 28.3 °C (based on 52 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00406 - 0.01076), b=3.09 (2.95 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.6 se; based on size and trophs of closest relatives
Generation time: 18.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High to very high vulnerability (68 of 100) .
