The sawfish's saw is actually an elongation of their head lined with teeth. It contains thousands of ampullary pores which the sawfish uses to detect minute electric fields which surround its prey. The saw is used to find food by digging in the ocean's bottom and by slashing free-swimming fish. The Melbourne Aquarium in Melbourne, Australia has a marvelous collection of Southern Ocean and Antarctic species, as well as a large variety of sharks and rays. AIMG_5862
