Estimates based on models
Preferred temperature (Ref. 115969
): 20.1 - 28, mean 26.5 °C (based on 628 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03631 (0.01732 - 0.07611), b=2.81 (2.62 - 3.00), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Fec assumed to be > 10,000).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
