Estimates based on models
Preferred temperature (Ref.
123201): 3.9 - 4.7, mean 4.3 °C (based on 9 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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.

Trophic level (Ref.
69278): 4.2 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref.
