Etymology: Crenicichla: Latin, crenulatus = cut, clipped + Greek, kichle = wrasse (Ref. 45335); hemera: From the Greek hemeros (tame), in reference to the docile behavior of the type series when collected. More on author: Kullander.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
South America: Amazon River basin, in the upper Aripuanã River in the Madeira River drainage.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.7 cm SL male/unsexed; (Ref. 26677)
Morphology | Morphometrics
(total): 19 - 21;
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. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00349 - 0.01806), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 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.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
