Bayesian length-weight: a=0.00724 (0.00342 - 0.01532), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.46 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=7).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100) .
