Bayesian length-weight: a=0.00380 (0.00171 - 0.00845), b=3.06 (2.88 - 3.24), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec=4).
Vulnerability (Ref. 59153
