Краткое описание
определительные ключи | морфология | морфометрия
This species is distinguished from all congeners by the following characters: with a highly superior mouth, the lower jaw projecting upwards beyond the upper jaw (vs. terminal in calhamazon, orthos, patriciae, raptor, rex, schotti and sub-terminal in orinoco, sima); a strongly concave dorsal margin of the frontal (vs. straight in calhamazon, orthos, patriciae, raptor, rex, schotti and convex in orinoco, sima) (shared with Eastern Amazonian populations of S. orthos) (Ref. 126780).
Inhabit deep channels of white-water and black-water rivers (Ref. 13085); collected at low densities. Stomach content analysis indicates that it feeds entirely on the tails and scales of other electric fishes (Ref. 126780).
