Bayesian length-weight: a=0.00437 (0.00184 - 0.01038), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 se; based on food items.
Weerstandsvermogen
Kwetsbaarheid (Ref. 59153):  Low to moderate vulnerability (29 of 100) .
