Bayesian length-weight: a=0.00589 (0.00332 - 0.01045), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.1 ±0.1 se; based on diet studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (25 of 100) .
