Estimates based on models
Preferred temperature (Ref. 115969
): 23.9 - 29.3, mean 27.5 °C (based on 1552 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.7 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 (10 of 100) .
