India has a staggering variety of flora and fauna, including some of the rarest species in existence on the planet. There is so far a paucity of information for the general public on the status, biology, and major threats to the endangered species of our country. As per the latest  quantitative evaluation done by the International Union for Conservation of Nature (IUCN) there are 57 critically endangered species of animals in India. This booklet on “Critically Endangered Animal Species of India”- a pioneering attempt by the Ministry of Environment and Forests in collaboration with Zoological Survey of India to, for the first time, catalogue and share information on these species, presented in a concise and visually appealing format.
