Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 2; Raios dorsais moles (total): 7; Espinhos anais 1; Raios anais moles: 5. Hisonotus montanus can be distinguished from other congeners, except Hisonotus aky and Hisonotus iota by having an infraorbital canal entering the infraorbital series via the compound pterotic vs.
infraorbital canal entering the infraorbital series via the sphenotic. It is distinguished from Hisonotus aky and Hisonotus iota by having wider light stripes on the dorsal surface of head extending from snout tip to posterior end of compound pterotic, and by the presence of white marks on dorsal surface of head vs. narrow light stripes on dorsal surface of head extending from snout tip to posterior end of compound pterotic, and absence of white marks on dorsal surface of head (Ref. 80996).
Facultative air-breathing in the genus (Ref. 126274); Hisonotus montanus is found at high altitudes, about 850 m above the sea level, and represents the species of
Hisonotus occurring in the most elevated portions of the rio Uruguai basin (Ref. 80996).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00337 - 0.01709), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Fishing Vulnerability (Ref.
