How does the fish move? What sense organ helps to determine the strength and direction of the flow?

The movements of fish are not very diverse, but many of them are feasible relative to all planes. All movements are controlled by the organs of touch, specifically by the lateral line. It is with the help of it that the fish can perceive the direction and movement of water, its pressure and the strength of the flow. Regulation at the level of the brain occurs in its oblong section, through which the centers of respiration, circulatory system, digestive and the centers of the sense organs – the lateral line, hearing, touch, taste and smell – are innervated.
