50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.7 ±0.5 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
