Spadenose shark (Scoliodon laticaudus) fish species information

Scientific Name
Scoliodon laticaudus

Common Name
Spadenose shark

Biology
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). Feeds 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).
