Estimates based on models
Preferred temperature (Ref. 115969
): 0.3 - 0.7, mean 0.4 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.1 se; based on size and trophs of closest relatives
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
