    • Long-billed vulture (Gyps indicus), also known as the Indian vulture (44,000) 
    • Why Vulture numbers were fast declining in India?
      • Diclofenac , a painkilling drug administered to cattle, is the main cause of mass extinction of vultures. 
      • Vultures, which have a digestive system robust enough to even digest disease-causing pathogens found in rotting meat of dead, do not have a critical enzyme that breaks down diclofenac and die of renal failure after eating carcasses of cattle administered the drug. 
      • Vultures feeding on cattle either die from acute kidney failure within a few days or lose their ability to reproduce. 
  • Endangered species are the King cobra, Indian crocodile (mugger), South Andaman krait and four kinds of turtles namely, Red-crowned Roofed Turtle, Bengal Roof Turtle, Jaggedshelled turtle and Hawksbill turtle. These species were identified to be extinct forever.
