• Lower mouth

Lower mouth - the lower jaw is shorter than the upper jaw. The mouth is located on the lower side of the body. It is characteristic of benthophagous fishes that feed on bottom organisms (gudgeon, whiskers, mullet, Siberian char, etc.). Some fish sometimes have a semi-lower mouth (bream, whitefish, teal, muksun). The lower mouth may be oblique, as in the fish, or transverse, as in the podust, chromuli.
