For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered reptiles are listed ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta

It does not rear upwards, produces only a slight flattening of the neck when threatened, and is ...
The most important factors in the difference of mortality rates among victims envenomated by cobras is the severity of the bite and which cobra species caused the envenomation. The Caspian cobra (N. oxiana) and the Philippine cobra (N. philippinensis) are the two cobra species with the most toxic venom based on LD 50 studies on mice.
The report's co-author, Ellen Butcher, stated one of the guiding principles of the list, "If we take immediate action we can give them a fighting chance for survival. But this requires society to support the moral and ethical position that all species have an inherent right to exist." [1] [5]
The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR. Order Crocodilia (crocodilians) [ edit ]
Endangered and critically endangered species also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered reptiles, List of critically endangered reptiles. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.
