Morphological structure and peripheral innervation of the lateral line system in the Siberian sturgeon ( Acipenser baerii )
Abstract Light and scanning electron microscopy (SEM) were used to study the epidermal lateral line system of the Siberian sturgeon ( Acipenser baerii Brandt, 1869). This system consists of mechanoreceptive neuromasts, ampullae and the electroreceptive organ. The neuromasts are located in 5 pairs of...
