Invertebrate species (IUCN, 2015.4)
  • 17,516 species have been evaluated
  • 12,389 are fully assessed (excludes DD)
  • 7778 are not threatened at present (LC, NT, LR/cd)
  • 4201 are threatened (CR, EN, VU)
  • 410 to 609 are extinct or extinct in the wild (EX, EW, CR(PE), CR(PEW))
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild.

As of February 2016, the International Union for Conservation of Nature (IUCN) lists 2121 vulnerable invertebrate species.[1] 12% of all evaluated invertebrate species are listed as vulnerable. The IUCN also lists 45 invertebrate subspecies as vulnerable.

No subpopulations of invertebrates have been evaluated by the IUCN.

For a species to be assessed as vulnerable to extinction, the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species face an even higher risk, and are listed separately even though they also meet the quantitative criteria for vulnerable species: List of endangered invertebrates, List of critically endangered invertebrates. The three categories combined are referred to as threatened species.

Additionally 5127 invertebrate species (29% of those evaluated) are listed as data deficient, meaning there is insufficient 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.[2] 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."[3]

This is a complete list of vulnerable invertebrate species and subspecies as evaluated by the IUCN. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.
