Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Μαλακές εδρικές ακτίνες: 227 - 255. Electric organ present along caudal filament and along body above anal fin exceedingly deep and visible as large semi-translucent area, occupying approximately 14-17% body depth directly posterior to abdominal cavity; and monophasic, headpositive electric organ discharge (EOD) waveform, approximately 2.1 milliseconds in duration in both sexes at 25°C (Ref. 94132).
Facultative air-breathing in the genus (Ref. 126274); Usually found in floating meadow habitats on the margins of the Amazonas/Solimões River and its tributaries. Often collected with Brachyhypopomus walteri (Ref. 94132).
