الأشواك الظهرية (المجموع) : 18 - 35; الأشعة الظهرية الناعمة (المجموع) : 64 - 73; شوكة شرجية: 2; أشعه شرجية لينه: 67 - 80; فقرات: 95 - 96. Diagnosis: Anterior nostril in the form of a short tentacle; snout produced as a fleshy appendage (Ref. 34290). Number of dorsal-fin spines 18-35; anal fin with 2 separate spines (Ref. 34290, 123814). Colour extremely variable, ground colour brown with a variable reticulated and blotched pattern (Ref. 34290).

Mainly riverine species, but also occurs in lakes near river mouths and in vegetated fringes and in swamps (Ref. 80296). Also found in rapids where it hides among rocks (Ref. 85214). Essentially a sedentary fish, nocturnal and usually waiting for its prey to swim or drift within range whereupon fish will dart out of its shelter to seize it (Ref. 89002). Feeds on aquatic insect larvae (Ref. 80296), lithophilic insects (Ref. 12526), fish (Ref. 13624, 27292), shrimps (Ref. 246, 80296), oligochetes and occasionally vegetable matter (Ref. 80296, 89002). Breeds during flood season, in inundated areas (Ref. 80296). Eggs yellow and large, probably spawned among water weeds (Ref. 89002).
