Python molurus
The river Cauvery is also habitat for various species of reptiles like the mugger crocodile ("Crocodylus palustris"), Indian mud turtles ("Chelonia" sp.). Reptile species in the sanctuary are Indian rock python ("Python molurus"), Indian cobra ("Naja naja"), Russell’s viper ("Daboia russelii") and banded krait ("Bungarus fasciatus"). This is also one of the few places to find the IUCN Red List Critically Endangered hump-backed mahseer ("Tor remadevii" ) fish. It was also, previously, part of the distribution of the Critically Endangered Nilgiri Mystus ("Hemibagrus punctatus"), known locally as "haddu."
