Economic Importance and Threats
Importance:  Commercial, Dangers
(Fisheries, gamefish. Utilized for its fins and meat (both of very high value), and skin and cartilage. The saws sell as tourist souvenirs.
Traumatogenic)
Threats:  Anthropogenic
(The principal threat is fisheries, both targeted and bycatch, commercial and subsistence. Their morphology, particularly the long tooth-studded saw, makes them extraordinarily vulnerable to entanglement in any sort of net gear, including primitive fishing technology, and regardless of population size (which was probably always fairly small). When sawfish are taken in bycatch, they are often retained (particularly in areas where there is no legal protection) because of the very high value of their products (meat is high quality and fins and rostral saws extremely valuable in international trade). They are also targeted opportunistically for the same reasons.)

Ecology
Habitat:  Demersal, Estuarine, Sandy, Coastal
Trophic Level:  Tertiary Consumer
Prey:  Benthic crustaceans, mollusks, finfish, bony fish
IUCN Status:  Critically Endangered
