Comments: Type locality of Tor remadevii, Pambar, the southern-most tributary of the River Cauvery in Kerala. It is endemic to River Cauvery, Karnataka, Kerala, Tamil Nadu. Tor remadevii is currently known only from the eastward flowing River Cauvery and its tributaries including the Moyar, Kabini, Bhavani and the Pambar, in the Western Ghats Hotspot of peninsular India (Ref. 123468). Also known from Chambakkad and Koottar regions of river Pambar in Chinnar Wildlife Sanctuary, Kerala, southern India (Ref. 88141). Status of threat: Critically endangered: following its collapse in recruitment in the main river population during the mid-2000s (Pinder et al. 2015b), the only spawning populations currently known to persist are restricted to a 40 km reach of the River Moyar, Tamil Nadu (Pinder et al. 2018a) and the Pambar River in Kerala. The status is because of the alarming population size reduction and persistent threats (Ref. 123468).

Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 4; Raios dorsais moles (total): 9; Espinhos anais 2; Raios anais moles: 5. This species is characterised by having D IV,9; A II,5. It differs from its congeners in India by the following: a prominent hump originating above the pre-opercle and extending to the origin of the dorsal fin; a well-developed mandible resulting in a terminal or slightly superior mouth position; the dorsal orientation of the eyes; a distinctive kink in the profile of the pre-opercle, a consistent feature in T. remadevii and not observed in other South Indian Tor. Similar to other Tor species the mouth morphology is highly variable, with some individuals exhibiting hypotrophic lips and sub-terminal mouth with enlarged mentum. Colouration of the body varies (silver, bronze, greenish) and is not considered a reliable diagnostic character; the orange coloration of the caudal fin (sometimes extending to all fins) is considered a more consistent character (Ref.123478).

While functional habitats are yet to be elucidated, T. remadevii inhabits the middle to upper reaches of the River Cauvery and some of its tributaries. Mesohabitat utilization is known to incorporate shallow high velocity rapids to deep, slow flowing pools, with substrates typically composed of bedrock and boulders (Ref. 123478).
