Bayesian length-weight: a=0.00741 (0.00293 - 0.01878), b=3.11 (2.89 - 3.33), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.0 ±0.00 se; Based on food items.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (32 of 100) .
