Preferred temperature (Ref. 115969
): 5.7 - 7.8, mean 7.1 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00132 (0.00055 - 0.00315), b=2.93 (2.73 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
