Frequently asked questions

How many threatened species are in Antarctica?
Antarctica has 25 threatened species recorded on SpeciesRadar — 6 of those are Critically Endangered, facing an extremely high risk of extinction. The figures combine IUCN Red List data with national red list assessments where available.
How many Critically Endangered, Endangered, and Vulnerable species does Antarctica have?
Of the 25 threatened species in Antarctica, 6 are Critically Endangered, 6 are Endangered, and 13 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Antarctica?
Among the 6 Critically Endangered species in Antarctica, Macandrevia cranium is one of the most at-risk — featured prominently on the country dashboard. The full list of Critically Endangered species is filterable on the Species tab.
What protected areas exist in Antarctica?
SpeciesRadar does not yet catalogue protected areas for Antarctica. Where available, protected-area data is drawn from the World Database on Protected Areas (WDPA) and national designations.
Which animal and plant groups are most threatened in Antarctica?
The most affected groups in Antarctica, by number of threatened species, are fishes (11), other invertebrates (4), and fungi (3). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Antarctica?
The leading threats to threatened species in Antarctica are fishing & harvesting aquatic resources, habitat shifting & alteration, ocean acidification, and logging & wood harvesting. Each threat is mapped to the species it affects in the country's threat breakdown.
How many of Antarctica's threatened species have declining populations?
10 of Antarctica's threatened species have populations that are still declining. Reversing these trends is the central focus of the conservation work the country dashboard tracks.
How does Antarctica compare to other countries for threatened species?
Antarctica ranks #237 of 250 countries by number of threatened species, and accounts for roughly 0.04% of all threatened species tracked worldwide. Threat is geographically concentrated, so a high rank reflects both rich biodiversity and intense pressure on it.
Where does the data for Antarctica come from, and can I download it?
SpeciesRadar draws on the IUCN Red List, the Global Biodiversity Information Facility (GBIF), the World Database on Protected Areas, and national red lists. Every table on the Antarctica profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
