Morphology | Morphometrics
soft rays: 8 - 9. Mid-lateral scales 62-65; horizontal scales rows 19-20; predorsal scales 40-48. Generally dark brown dorsally, lighter below with a series of close-set, narrow dark brown stripes on sides. Median and pelvic fins with small dark spots. Pectoral fins with rows of dark spots forming transverse bands. Juveniles often whitish grey dorsally with a narrow white stripe (or irregular white blotches) along mid-line. Similar to O. lineolata but has spotted anal, pelvic, and pectoral fins (Ref. 44894).
Inhabits rivers, creeks and billabongs, usually in quiet o slowly flowing water among vegetation, around log debris or undercut banks. A nocturnal carnivore, feeds on fishes, crustaceans, and aquatic insects (Ref. 44894).
