Estimates of some properties based on models
Preferred temperature (Ref.
115969): 20.4 - 27.2, mean 24.5 (based on 103 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00240 (0.00119 - 0.00483), b=3.15 (2.98 - 3.32), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.7 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref.
59153): High vulnerability (63 of 100) .
