Etymology: Apteronotus: Greek, apteros = without wings / (in this cases, fins) + Greek, noton = back (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range

; 淡水 底中水层性. 熱帶; 24°C - 28°C (Ref. 2059)
South America: the Guianas, Brazil and Peru; rivers of Colombia and Venezuela, including the Catatumbo River.
南美洲: 圭亞那巴西與祕魯; 哥倫比亞與委內瑞拉的河, 包括 Catatumbo 河。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 13.0, range 13 - ? cm
Max length : 26.9 cm TL 雄鱼/尚未辨别雌雄; (Ref. 36886)
Dorsal fin reduced to a dorsal filament;
背鳍缩小成一个背部的丝状突起了;
Prefers fast flowing rivers (Ref. 26543). Forms loosely associated groups in rocky habitats or river banks (Ref. 10605). Nocturnal (Ref. 26543). Each individual fish possesses a unique spatiotemporal pattern of electric organ discharge (EOD) potentials distributed over the body surface (Ref. 10595). Chirps and EOD frequency modulations are important elements of courtship behavior and are sensitive to testosterone levels (Ref. 10011, 10883). Seems to reach sexual maturity at 1 year of age, based on breeding experiments (Ref. 10011). Tuberous electro receptors are differentiated and functional in larvae at day 9; electric organ and electro receptors both present in the larvae at the time of first exogenous feeding (Ref. 10605).
