Short description आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण): 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 33-35; गुदा कांटा 0; ऐनल सौफट रेज़: 22 - 28. Characterized by a single row of 1 to 4 bony plates along the midventral line between the anus and the anal fin, and about 33 to 35 rays in the dorsal fin. Dorsal arises at posterior third of the total length; anal fin arises under posterior part of dorsal; pectorals originate low on the body just behind gill opening and are large and rounded; pelvic fins arise near the anus. Generally olive to dark green, lower parts more or less whitish green; a longitudinal olive-green stripe on side between lateral and ventrolateral plates, another on midventral surface; fins grayish to pale green (Ref. 27547). Barbels usually situated closer to mouth than to snout tip; coloration of scutes along side paler than skin (Ref. 86798).
