List of critically endangered reptiles facts for kids
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 195 critically endangered reptile species, including 17 which are tagged as possibly extinct. 3.8% of all evaluated reptile species are listed as critically endangered. The IUCN also lists 12 reptile subspecies as critically endangered.
Of the subpopulations of reptiles evaluated by the IUCN, ten species subpopulations have been assessed as critically endangered.
Additionally 910 reptile species (18% of those evaluated) are listed as data deficient, meaning there is not sufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".
This is a complete list of critically endangered reptile species and subspecies evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such. Species and subspecies which have critically endangered subpopulations (or stocks) are indicated.
