Lengte bij maturiteit / Grootte / Gewicht / Leeftijd

Maturity: L_m 50.8, range 45 - 56.5 cm
Max length : 94.2 cm TL mannelijk / geslacht onbekend; (Ref. 10652); 62.5 cm TL (female); common length : 30.0 cm TL mannelijk / geslacht onbekend; (Ref. 3265); max. gepubliceerd gewicht: 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).

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.
