Biology Glossary Search (e.g. epibenthic)
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).
IUCN Red List Status (Ref. 90363) Threat to humans
Near Threatened (NT) Harmless (Ref. 244)
