Estimates based on models
Preferred temperature (Ref. 115969
): 4.1 - 4.5, mean 4.3 °C (based on 7 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Vulnerability (Ref. 59153
): Low to moderate vulnerability (34 of 100) .
