Sawfish - Sydney Aquarium "The sawfish's most distinctive feature is the saw-like rostrum. The rostrum is covered with electrosensitive pores that allow the sawfish to detect slight movements of prey hiding in the muddy sea floor. The rostrum also serves as a digging tool to unearth buried crustaceans. Should suitable prey try to swim past, the normally lethargic sawfish springs from the bottom and slashes at it with its saw. This generally stuns or impales the prey sufficiently for the sawfish to devour it. Sawfish also defend themselves with their rostrum against intruding divers and predators such as sharks. The "teeth" protruding from the rostrum are not real teeth, but modified tooth-like structures called denticles." en.wikipedia.org/wiki/Sawfish AIMG 8162

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
