Estimates based on models
Preferred temperature (Ref.
115969): 6.6 - 9, mean 7.3 °C (based on 7 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00147 - 0.00678), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100) .
