Grasshoppers have no ears, instead they use an organ called the tympanum located in the first segment of their abdomen, whereas humans take in sound waves through the ear canal until they reach the eardrum. The eardrum picks up the vibrations and then transmits them to tiny bones in the middle of the ear, the bones pass the vibrations to the inner ear (which is filled with liquid) and the cochlea.
Hope I could help.
One good reason would be that they could give someone, or many people who are in desperate need of a new organ, a second chance at life.
