Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 11 - 12; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 8. Anterior barbels very thick and dark, length less than 5.5 times in head length, less than 2 times in gape height, longer than eye diameter; oral gape inferior; dorsal head profile irregular, convex caudally and with a 'bump' caused by premaxillaries.
Over muddy, sandy and rocky substrates all over the lake, preferably in water deeper than 6 m. Feeds mainly on insect larvae, small mollusks, and detritus.
