Estimates based on models
Preferred temperature (Ref. 115969
): 25.1 - 29.2, mean 27.3 (based on 528 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00143 - 0.00883), b=3.07 (2.85 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Fec is assumed to be <10).
Vulnerability (Ref. 59153
): High vulnerability (62 of 100) .
