संक्षिप्त वर्णन
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 0. With 61 - 67 trunk myomeres; trunk not mottled in live ammocoetes. The caudal fin is hyaline, of a spade-like shape.
Body shape (shape guide): eel-like; Cross section: circular.
Adults inhabit clear, well-oxygenated brooks in piedmont and mountain zones. They are non-parasitic and remain in freshwater. Ammocoetes live in detritus-rich sands or clay sediments. Ammocoete stage lasts 3.5-4.5 years. Ammocoetes feed on detritus and micro-organisms. They metamorphose in July - September and spawn in March - May. Males dig shallow nests in habitats with moderate currents (Ref. 59043). Males and females die after spawning.

Males dig shallow nests in habitats with moderate current. Spawning occurs when temperature reach 7-10°C at higher elevations (Ref. 59043).
