Etymology: Pygocentrus: Greek, pyge = rump + Greek, kentron = sting (Ref. 45335).
The genus allocation is uncertain, it could be in Serrasalmus Lacepède, 1803 according to Nico 2001. Please send references or more studies are needed.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00860 - 0.03849), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.76 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (18 of 100).
