List of critically endangered arthropods
As of July 2016, the International Union for Conservation of Nature (IUCN) listed 394 critically endangered arthropod species, including 86 which are tagged as possibly extinct. 4.1% of all evaluated arthropod species are listed as critically endangered. The IUCN also lists three arthropod subspecies as critically endangered. No subpopulations of arthropods have been evaluated by the IUCN. Additionally 2875 arthropod species (30% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status.
