Bayesian length-weight: a=0.01905 (0.01074 - 0.03380), b=2.97 (2.82 - 3.12), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.22-0.24).
Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100) .
