Hearing is well-developed in carp, which have the Weberian organ, three specialized vertebral processes that transfer vibrations in the swim bladder to the inner ear. Although it is hard to test sharks' hearing, they may have a sharp sense of hearing and can possibly hear prey many miles away. [10]
