Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal spines: 2; Anal soft rays: 9. Diagnosis: pectoral-fin tips reaching to pelvic-fin bases; pelvic-fin insertions located on a vertical line from last dorsal-fin ray: snout length less than 55% of head length; posterior nostrils large, separated from orbits by a bony crest; humeral process blunt; branchiostegal membrane broadly notched ventrally; width of occipital process comprised 3.2 times in its length (Ref. 57128).

Phractura species are often associated with the vegetation of flowing waters (Ref. 57128).
