Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 20 - 26; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 26 - 30. Diagnosis: Marcusenius altisambesi can be distinguished from its congeners by the following characters: scales around caudal peduncle 12-14; scales in linear series along the lateral line row 49-60; anal fin rays 26-30; dorsal fin rays 20-26; and body depth 20.1-32.8% of standard length (Ref. 75962). Electric organ discharge (EOD) with weak head-negative pre-potential in juveniles and females, sexual dimorphism in EOD waveform present in the 'summer' in the form of greatly increased EOD duration in sexually mature males of greater than about 12.5 cm standard length, but dimorphism not confirmed for specimens from Okavango (Ref. 75962).
