Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 19 - 21; Dorsal soft rays (total): 13 - 14; Anal spines: 3; Anal soft rays: 9 - 12; Vertebrae: 35. Easily distinguished from all other species of the genus by having a row of dark blotches forming a more or less continuous band along the abdominal side, and by having infraorbitals 3 and 4 co-ossified instead of separate. Differs from most Crenicichla species in having a smooth-margined instead of serrated preopercle (Ref. 26677).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00338 - 0.01626), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
