Bayesian length-weight: a=0.00339 (0.00148 - 0.00774), b=3.11 (2.91 - 3.31), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.4 ±0.63 se; Based on food items.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (49 of 100) .
