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. |
