About Assam cascade frog:

  • It is mainly distributed across the Himalayan belt in India and found in high-flowing and gradient streams of northern Bangladesh, Bhutan and Nepal.

  • The genus Amolops comprises 72 distinct species distributed throughout the hilly regions with fast-flowing streams in southern and Southeast Asia.

  • Conservation status
    • IUCN: Least Concern
