Circumglobally in tropical and subtropical waters, entering estuaries and littoral lagoons and ascending river courses (Ref. 81284, 81624). Western Atlantic: Florida and Louisiana, USA to Brazil (Ref. 7251); eastern Atlantic: Portugal to Angola, including the western Mediterranean Sea (Ref. 4429; no report since the 19th century [Ref. 116564] ); western Pacific: northern Australia, from western Australia to Queensland (Ref. 7300); eastern Pacific: Gulf of California to Ecuador (Ref. 4429). In freshwater it can be found in rivers of West Africa (Ref. 81284), Ogowe River (Ref. 81284) and the Congo River estuary (Ref. 377, 81284).

Diagnosis: Rostral blade with 20 or fewer pairs of rostral spines (Ref. 81624).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

A euryhaline species (Ref. 57533). Inhabits inshore coastal waters to moderate depth, also around off lying islands. Found also in estuaries, lagoons, river mouths, and even freshwater. Feeds on fishes and bottom-living animals. Ovoviviparous. Apparently can reproduce in freshwater (Ref. 57533). Freshwater populations occur to about 750 km up Amazon River; populations in Lake Nicaragua may be non-migratory (Ref. 7251). Reaches sexual maturity at 8-10 years and females have litters of approximately 1-13 pups. Young spend much of their early life in rivers up to 400 km from the sea (Ref. 114953).
