in fish are used to detect water movements around their bodies. These hair cells are embedded in a jelly-like protrusion called cupula. The hair cells therefore can not be seen and do not appear on the surface of skin.
The 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. The are hair cells, the same mechanoreceptors for sense and hearing. It is used primarily for navigation, hunting, and schooling. The receptors of the electrical sense are modified hair cells of the lateral line system.

Water depth is a major factor influencing water temperature. Since heat comes from the sun, water tends to be warmer near the surface and cooler with increasing depth. Because of this, much of the discussion about how water temperature influences fish behavior tends to center on the surface and the area immediately under it.Fish are unable to regulate their body temperature, so they are influenced by the temperature around them. If the water is warm, fish metabolism accelerates, feeding and respiration increases, and there is a general increase in movement. If the water is cooler, fish become lethargic and tend to be inactive. However, this is also true for other water creatures such as the insects that some fish eat, and certain fishes have adapted to this fact by specializing in slower kinds of prey. This is why bass and carp fishing is done in winter. These are fish specializing in slow-moving prey, and they are more active in cold water than in warm water. In general, however, most types of fish prefer faster prey and are more active in warmer water.However, currents also bring water of differing temperature together, and areas where this occurs can be zones of intense fish activity. Such areas are called oceanic fronts, and their sudden temperature changes encourage the growth of plankton. Plumes of plankton occurring at oceanic fronts attract fish which feed on either the plankton itself or on other fishes that consume it.There is an old cliche which says that a fish doesn’t know he is in water. He is born there, and he spends every moment of his life there. Unless a fish is ever taken out of water, he does not know anything different. Perhaps if fish are able to communicate with each other, one who has been outside of water can tell others about it, but that feels like something which needs to be experienced.
