колючие лучи спинного плавника (общее число) : 1. The head is more or less flattened, the nostril nearly rounded, mouth inferior. There are three pairs of barbels, 1 pair of maxillary barbel and 2 pairs of mandibular barbels.
Inhabits mainly brackish estuaries and lagoons. Occurs also in freshwaters (Ref. 58022). Found on shallow muddy bottoms (Ref. 5217). Feeds on fish and shrimps. Two annual cycles of slower growth occur during the dry seasons (March and August to November). Life span is three to four years. Sexually mature at 1.5 to 2 years of age. Reproduction takes place from November to April. Consumed as food (Ref. 35381). Marketed fresh. The skull is sold throughout the world as crucifix.
Pairing involved in reproduction. Mouth brooding may be employed (Ref. 205).
