gather and process information from secondary sources to outline and compare some of the structures used by animals other than humans to produce sound Structures used by other animals to produce sound Animals have several different methods of producing sound, e.g. larynx emits ultrasonic (high frequency sound) waves Bats – – allows them to search for prey + avoid obstacles in the darkness NOTE: most terrestrial vertebrates use their breathing system to produce sounds produce sounds by rubbing fins or gills OR by Fish – vibrating their swim bladder (gas filled sac that regulates buoyancy) rub veins on bases of their forewings Male grasshoppers + crickets – (stridulation) OR rub inner surfaces of their hind legs produce a loud sound by rapidly expelling a water Snapping shrimp – bubble from within their large claw
