Web26 de dez. de 2024 · Movement of Fish in Water. Fish are vertebrates. All vertebrates have an internal skeleton made up of bones; a tough, elastic substance called cartilage; or both. Most fish have a streamlined body – the head and the tail are narrow; the middle portion of the body is broader. This kind of shape offers least resistance to the flow of … Web17 de mar. de 2024 · Fish have a row of special cells inside a special canal along the surface of the fish’s skin. This is called the “lateral line” which allows them to detect water vibrations. This sixth sense allows fish to detect movement around them and changes in water flow. Detecting movement helps fish find prey or escape from predators.

In recent years, high powered laser systems operating in the blue- green portion of the visible spectrum (lidar) have shown promise for the evaluation of fishery resources. A lidar carried on aircraft flying at an approximate altitude of 1700 m can detect fish at depths to 16 m.

The lateral line in fish and aquatic forms of amphibians is a detection system of water currents, consisting mostly of vortices. The lateral line is also sensitive to low-frequency vibrations. It is used primarily for navigation, hunting, and schooling. The mechanoreceptors are hair cells, the same mechanoreceptors for vestibular sense and hearing. Hair cells in fish are used to detect water movements around their bodies.
