List of near threatened invertebrates

In July 2016, the International Union for Conservation of Nature (IUCN) listed 1105 near threatened invertebrate species.[1] Of all evaluated invertebrate species, 6.1% are listed as near threatened. The IUCN also lists 15 invertebrate subspecies as near threatened.

16 extinct in the wild invertebrate species (0.09%)987 critically endangered invertebrate species (5.6%)1163 endangered invertebrate species (6.6%)2178 vulnerable invertebrate species (12%)1105 near threatened invertebrate species (6.3%)6919 least concern invertebrate species (39%)5278 data deficient invertebrate species (30%)
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)
    • 206 possibly extinct [CR(PE)]
    • 0 possibly extinct in the wild [CR(PEW)]
  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) status, 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.
