Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00390 - 0.02813), b=2.87 (2.64 - 3.10), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.3 se; Based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).
Verwundbarkeit (Ref. 59153):  Low to moderate vulnerability (33 of 100) .
