Sense organs fish organ, structural features, functions.

The eyes of fish have a spherical lens and a flat cornea, which is why fish see so well in water at a short distance. The ability of the eye to adapt to a clear distinction of objects is achieved by changing the distance from the lens to the cornea. In bony fish, vision is colored.
The organs of smell are olfactory sacs, which are lined with sensitive epithelium. The olfactory organs communicate with the external environment through the nostrils.
The organs of touch are the receptors of the skin and the organs of taste – the taste buds in the oral mucosa.
The organ of hearing is only the inner ear. Sound vibrations are transmitted to him from the water through the bones of the skull.
The lateral line is an organ of the seismosensory sense that perceives water vibrations. It is a channel in the thickness of the skin on the sides of the body, which has a series of holes, which also contains mechanoreceptors.
