Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturidade: Lm 38.3, range 33 - 76.5 cm
Max length : 100.0 cm TL macho/indeterminado; (Ref. 5450); idade máx. registrada: 6 anos (Ref. 244)
Espinhos dorsais (total) : 0; Espinhos anais: 0. Bronze grey above, white below, fins sometimes darker than body; no conspicuous markings (Ref. 9997).
Body shape (shape guide): fusiform / normal.
Found on rocky substrates of coastal waters and lower reaches of tropical rivers (Ref. 244). It is uncertain, however, if this species can live in perfectly fresh water for extended periods (Ref. 244). Forms large schools (Ref. 244). Adults feed on small bony fishes, shrimps and cuttlefish (Ref. 244). Viviparous (Ref. 50449). Common by-catch of the inshore demersal gillnet fisheries, particularly those operating off Kalimantan (Ref.58048). Utilized fresh for human consumption; processed into fishmeal and used as bait for other sharks and bony fishes (Ref. 244). Maximum sizes up to 120 cm unconfirmed (Ref. 244).
Viviparous, with an unusual columnar placenta (Ref. 244). Maternal and foetal placenta comprises the entire placenta (Ref. 39556). Transplacental nutrient transfer may be hemotrophic (Ref. 39556). Litter size varies from 1 (Ref. 58048) to 14 (Ref. 9997). Size at birth about 13 to 15 cm TL (Ref. 9997). Distinct pairing with embrace (Ref. 205).
