Estimates of some properties based on models
Preferred temperature (Ref.
115969): 2.3 - 3.2, mean 2.5 (based on 82 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00097 - 0.00495), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic Level (Ref.
69278): 4.0 ±0.64 se; Based on food items.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
