Estimates based on models
Preferred temperature (Ref.
123201): 12.1 - 19.6, mean 15.9 °C (based on 110 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00335 - 0.00989), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.7 ±0.3 se; based on size and trophs of closest relatives
Resiliens (Ref.
