Short description
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 47 - 51; Mjukstrålar i analfenan: 31 - 33; Ryggkotor: 53 - 55. Dorsal surface of the body dark; 8-11 irregular (often anteriorly pointed V-shaped) black blotches or bands on upper half of the body; a white-rimmed black ocellus on caudal peduncle; sparse white spots on body and dorsal and caudal fins. Hyomandibular process with the mid- to lower lateral edge mesially protruded. One to 2 small to medium-sized scales found on the undersurface of each side of the lower jaw. Pelvic fin absent. Cheek scales 9-13 (Ref. 43157).
Obligate air-breathing (Ref. 126274); Generally restricted to relatively narrow regions, characterized by humid rainforest climate (Ref. 43157).
