Orange-finned Mahseer

Tor remadeviae, the orange-finned mahseer, also known as the hump-backed mahseer, is a critically endangered species of freshwater fish endemic to the Western Ghats of India. It is restricted to the Kaveri river basin.

It can be distinguished from other mahseer by the prominent hump originating above the pre-opercle, a distinctive kink in the pre-opercule, a terminal mouth position, and its bright orange caudal fin. It is considered a high-quality game fish, and has been proclaimed by anglers as "the largest and hardest fighting freshwater fish in the world".
