背棘 (总数) : 18 - 35; 背的软条 (总数) : 64 - 73; 臀棘: 2; 臀鳍软条: 67 - 80; 脊椎骨: 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).
前鼻孔形成一个短的触须。吻延长形成一个肉质的附肢了。臀鳍有 2根个别的棘。颜色非常可变, 底色褐色的有一可变的成网状而且大斑点图案.(参考文献 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).

出现于沼泽与沿岸浅水区。 (参考文献 6060) 吃鱼与昆虫。 (参考文献 13624)
