Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
In crisis
Among the reasons for the species' extreme threat status is the introduction of non-native mahseers Tor khudree and Himalayan golden mahseer (Tor putitora) to the wider Kaveri river basin. Despite this endangered status, the general lack of a formal scientific name had previously hampered efforts to protect the species. Even so, a 2018 study found that the orange-finned mahseer was in fact conspecific with Tor remadeviae, a little-known species identified in 2007 based on 19 individuals sampled from the Pambar River in 2004.
