LATERAL LINE SYSTEM

Definition

A tubular sensory organ of fishes and aquatic life stages of amphibians that is located along the sides of the body and on parts of the head. It is used to perceive water movements (turbulences), current changes, differences in pressure, etc. Typically, it extends from the shoulder girdle to the base of the tail but in some species it is shorter or may not even be present, or it can continue on to the tip of the tail fin. The receptors which end initially free in the epidermis, are located in channels connected with the open water medium via pores with plate-like cupulae. They exhibit important taxonomic characteristics.
