Sawfish

Sawfish have some of the most prized fins for shark fin soup, alongside tiger and mako sharks, and the meat is eaten as a secondary use. The saw and liver oil have also been used historically, with the oil once regarded in 1920s Florida as the best fish oil for eating.

Sawfish historically ranged across about 90 countries in tropical and subtropical waters, from Morocco to South Africa and New York to Uruguay, plus widely across the Indo-Pacific. They're euryhaline bottom-dwellers that stick to coastal marine and brackish estuary waters, usually less than 10 m deep, and the largetooth sawfish pushes far into freshwater, reported 1,340 km up the Amazon.
