Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 18.4 - 28.9, mean 23.2 (based on 278 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00447 (0.00177 - 0.01127), b=3.14 (2.92 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  4.3   ±0.8 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  Moderate vulnerability (36 of 100) .
