Etymology: Satanoperca: Taken from the prince of darkness. Hube liked to name cave fishes with diabolic names based on the idea of hell being underground + Greek, perke = perch (Ref. 45335). More on author: Heckel.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 24°C - 26°C (Ref. 2060)
South America: Amazon River basin, in the Branco, lower Negro, and along the Solimões-Amazon rivers in Brazil between the Tocantins and the lower Trombetas rivers.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.0 cm SL male/unsexed; (Ref. 36377)

Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Deposit eggs in troughs, covered with a little sand. Female tends the clutch, male defends the territory. This corrects previous information from Ref. 2060.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.01030 - 0.04649), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±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 (24 of 100) .
