Short description Claves de identificación | Morfología | Morfometría

This species is distinguished from all its congeners by the following: with a long snout, head length from the tip of the snout to the front of the eye) is 35-38% HL (vs. 24-32 %HL); eyes near the dorsal margin of the head (vs. eyes located on lateral margin of head in all species except S. duccis); maxilla with an enlarged anterior process greater than one-third the length of the descending blade (vs. reduced anterior process and less than one-third the length of descending maxillary blade); a robust oral dentition usually visible externally in mature specimens (vs. obscured dentition in all species except duccis, rex) (Ref. 126780).

Inhabit channels of white-water and black-water rivers (Ref. 13085). Stomach contents indicates that this species feeds on the scales and tails of other electric fishes (based on the presence of stacked scales, vertebrae and cartilaginous regenerated caudal filament rods) (Ref. 126780).
