Estimates based on models
Preferred temperature (Ref. 115969): 13.6 - 20.1, mean 18.3 °C (based on 34 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00141 - 0.00709), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Very high vulnerability (84 of 100) .
