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

How do fish move as a school? Fish have what’s called a lateral line - a vital sensory organ that runs from their gills to their tail. This “sixth sense” allows fish to detect movement and pressure changes in the water column. Which ultimately enables them to move as one without actually seeing what they’re swimming from! Not only does this sensory organ help fish hunt and avoid predators it also helps them, in this case navigate in low visibility. Next time you see fish moving as ONE being, wel
