背的軟條 (總數) : 10; 臀鰭軟條: 8. Schistura megalodonis distinguished by having a large processus dentiformes in the upper jaw, a short pre-anus length of 65.4%?66.3% of SL, long paired fins (pectoral: 20.8%?24.2% of SL; pelvic: 17.9%?20.6% of SL), a wide body of 9.7%?11.3% of SL at anal-fin origin, an incomplete lateral line, the absence of an orbital lobe, and a broad and distinct basicaudal bar with forward extensions (Ref. 103219).
Inhabits river with clear and moderate to fast running water over boulders, rocks, pebbles, sand, and twigs. Occurs together with Schizothorax malacanthus, Devario kakhienensis, Exostoma labiatum, Misgurnus anguillicaudatus, and Channa gachua.
