Many fish detect sound using a system called the lateral line, a network of tiny sensors running along their body. These sensors pick up pressure changes, vibrations, and water movement, allowing fish to sense predators, prey, and even distant disturbances without hearing in the human sense. Sound travels four times faster in water than in air, so vibrations reach fish long before anything is visible. Some species also use internal structures, like swim bladders, to amplify these vibrations. Ins

Fish Hearing Is Stranger Than You Think Fish hear with internal bones called otoliths. These bones grow rings that show their age. They connect to a lateral line that helps fish sense sound across their body. This makes their hearing very different from humans.
