Estimates based on models
Preferred temperature (Ref.
123201): 3.1 - 6.9, mean 4.1 °C (based on 86 cells).
Phylogenetic diversity index (Ref.

50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00407 - 0.02046), b=3.09 (2.88 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.3 ±0.3 se; based on size and trophs of closest relatives
Generation time: 15.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (tm=6; tmax=45 (validate age: 27 yrs)).
