Maturity: Lm 50.8, range 45 - 56.5 cm
Max length : 94.2 cm TL 雄鱼/尚未辨别雌雄; (Ref. 10652); 62.5 cm TL (female); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3265); 最大体重: 1.5 kg (Ref. 5217)
Adults occur in turbid estuaries, mangrove-lined lagoons and lower parts of rivers being very tolerant to changes in salinity. Found on shallow soft bottoms (Ref. 5217). Feed on a large variety of bottom-living and pelagic organisms including those found among the roots of mangroves. Reproduction occurs between September and December. A female lays 20-30 eggs, with a diameter of 10-12 mm. Males incubate the eggs in their mouth (Ref. 35381).

Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Females reach maturity at a younger age than males and grow faster. The male incubates 28-40 eggs in the mouth and 200-400 eggs that are fixed in a glutinous mass on its head. Incubation takes 10-12 days. After 50-60 days fully functional young (6-6.5 cm TL) are released.南美洲: 加勒比海與大西洋注入來自哥倫比亞到巴西的河與河口。
