Invertebrate species (IUCN, 2020.1)
  • 17,646 extant species have been evaluated
  • 12,368 of those are fully assessed[a]
  • 8024 are not threatened at present[b]
  • 4328 to 9606 are threatened[c]
  • 410 to 616 are extinct or extinct in the wild:
    • 395 extinct (EX) species[d]
    • 15 extinct in the wild (EW)

  1. ^ excludes data deficient evaluations.
  2. ^ NT, LR/cd, LC.
  3. ^ Threatened comprises CR, EN and VU. Upper estimate additionally includes DD.
  4. ^ Chart omits extinct (EX) species
Near Threatened (NT) species do not currently qualify for Critically Endangered (CR), Endangered (EN) or Vulnerable (VU), but are likely to qualify for a threatened category in the near future, or are already close to qualifying.

No subpopulations of invertebrates have been evaluated by the IUCN.
