The scales of this fish (fig. 5) are very large and cover each other for about three fifths of their length.
The scales in the middle of the body are almost perfectly round; those on the back and belly have an
irregular oval shape. The caudal edge of the scales is round or shaped like an irregular meandering line; the
outline usually has three sides which however are usually so faint, that the corners they form are indistinct.
The scales are divided in numerous small patches by a multitude of curved lines that cross each other
perpendicularly. The inner surface of the scales is smooth. The outer surface, on the larger caudal part,
where the scales cover each other, is provided with very fine line-like elevations (fig. 7), whereas the free
outer part is provided with grain-like elevations (fig. 6). The holes, which form the openings of the mucus
canal of the so-called lateral line, are very large (fig. 5). The lateral line begins at the scale that lies behind
the upper edge of the gill cover, and then slopes downward on the anterior smaller part of the body and
then continues almost in the middle of the fish to the root of the caudal fin where it disappears. The scales,
which are situated along the belly, along the bases of the dorsal and anal fins, and on the caudal peduncle,
are a much smaller than the other ones, much more irregularly shaped and on the basis of the fins form a
kind of sheath in which the fins can move.
