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).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

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

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).
