The sixth sense of fish

A group of scientists confirmed the fish has a "sixth sense" . The study found that thanks to this sense, the fish sensed the flow of water, the position of the prey, even knew in advance to avoid rough seas . This finding was published in Physical Review Letters.

The Daily Mail also quoted scientist Leif Ristroph as explaining that they had identified a unique layout of the "sensors" on the fish body surface. And this sensor system is almost as common in fish. This network of sensors is like a "hydrodynamic antenna" that allows fish to take signals about the flow of water and use this information in different behaviors, such as avoiding obstacles, know how to cross the whirlpools . without the aid of vision.

To find out how fish exploit flow information, research groups focus on a system of sensory sensory organs that detect both movement and vibration in the currents around them.

They specifically focused on the location of tiny 'channels' along the body, noting that this position may help explain how a sixth sense of fish senses. For example, the level of concentration of the head channels of the blind fish seems very suitable for detecting obstacles.

The team also built a plastic fish and successfully tested it like real fish.
