This efficient way of catching fish has allowed sawfish, or “carpenter sharks” as they are widely known, to survive on Earth for about 60 million years — surviving the mass extinction that wiped out dinosaurs. But even though sawfish outlived the dinosaurs, the question we must ask today on International Sawfish Day is whether they can survive the fishing activities of man. …
