Estimates based on models

Preferred temperature (Ref. 115969): 1.6 - 2.1, mean 1.8 (based on 438 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00240 - 0.00999), b=3.13 (2.96 - 3.30), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (85 of 100) .
