The International Union for Conservation of Nature and Natural Resources is an international organization that is involved in data gathering and analysis in the field of natural conservation and sustainable use of natural resources. They proposed various criteria that they use to determine a threatened species. A threatened species is one that is likely to become an endangered species in the near future throughout all or a significant portion of its range. Accordingly, threatened species is further categorized into: vulnerable species, endangered species, and critically endangered species. Vulnerable species, compared to other categories, are the least at risk of extinction. The endangered and the critically endangered species are more at risk of being wiped out altogether. They have the so-called Red List, which holds a comprehensive inventory of the global conservation status of biological species.
A critically endangered species is a species that is extremely likely to become extinct in the immediate future. Some of the species considered as critically endangered are as follows: Kemp’s ridley sea turtle, brown spider monkey, Chinese alligator, black rhino, northern hairy-nosed wombat, Philippine eagle, red wolf, Malayan tiger, northern white rhinoceros, etc.
