No endemic species of Nauru meet the strict criteria — this list is empty.
Nauru is a very small, low-lying Pacific island with little remaining native habitat. Endemic species require long-term isolation and varied habitats to evolve. Nauru’s tiny size, close biogeographic links to other Pacific islands, and severe habitat loss from phosphate mining make true island endemics unlikely.
Taxonomy and survey history also matter. Many animals on Nauru are widespread Pacific species or local populations of broader-ranging species. Scientific reviews and global databases (IUCN, GBIF, BirdLife) do not list any species found only on Nauru. That is a technical reason the strict “endemic to Nauru” category returns no results.
Look instead at related, informative categories. Find native species and regular visitors (seabirds like terns, noddies, boobies, and frigatebirds; migratory shorebirds). Check near-endemics or island-group endemics that occur on several nearby islands. Review extirpated or threatened species, and note introduced pests (rats, cats) and conservation actions. For detailed references, consult IUCN, BirdLife, GBIF, and Nauru government or regional biodiversity reports.
