Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 7; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9 - 10; गुदा कांटा: 1; ऐनल सौफट रेज़: 9 - 10. Species distinguished by females having 4-7 closely set, slightly flexible tricuspid premaxillary teeth and 2-4 canine-like teeth at the tips of the premaxilla; adult males with 4-7 premaxillary fixed recurved conical to canine-like teeth; females with 19-20 scales along lateral midline; small tongue, rounded and mostly free from floor of mouth anteriorly; pelvic disc fused to belly between fifth rays only (Ref. 75883).
Occurs in swift clear streams with rocky bottom; collected at an altitude of 147 m. Observed to swim in open water and are not always on the bottom of the river. Although feeding habits have not been studied, a few examined specimens apparently feed on aquatic insects and crustaceans (Atyidae) (ref. 75883).
