A Correct answer
Explanation

The correct answer is legs. Grasshoppers have a specialized auditory organ called a tympanal organ located on their abdomen, connected to their legs. They detect sound vibrations through their legs and can move them to triangulate the direction of sounds. This is different from mammals, whose ears are dedicated organs on the head. Grasshoppers' hearing system is an evolutionary adaptation that allows them to detect predators and communicate.
