Mains Level: Read the attached story
- The hump-backed Mahseer, found in the waters of the Cauvery, has been added to the IUCN Red List with Critically Endangered Status.
- The hump-backed mahseer is a large freshwater fish also called the tiger of the water and found only in the Cauvery river basin including Kerala’s Pambar, Kabini and Bhavani rivers.
- It is now “Critically Endangered”: more threatened than the tiger is, as per the IUCN’s Red List of Threatened Species.
- The fish is one of the 229 species added to the Red List last November; this update also reveals that the threat status of 12 other Indian species, including great hornbills, has increased.
- The inclusion was possible only once the fish got its scientific name last June—Tor remadevii.
5 other species added
- Five other species have also made it to threatened categories: two wild orchids, the Arabian scad (a marine fish) and two wild coffee species found only in a few localities in the Western Ghats.
More threats to Hornbill
- The great hornbill was earlier categorised as “Near Threatened”.
- It is now “Vulnerable” due to high hunting pressure coupled with habitat loss and deforestation, while the wreathed hornbill has moved from “Least Concern” to “Vulnerable”.
