No strictly endemic species are currently documented for the Marshall Islands.
Understand that “endemic” means a species found only in one place. The Marshall Islands are low, coral atolls with small land area and few habitat types. Those conditions make it rare for a wholly new species to evolve there and stay restricted to the islands.
Note the technical reasons behind this result. Endemism requires long isolation plus varied habitats like mountains or large islands. The Marshalls are geologically young and close enough to other Pacific islands that many plants and animals spread across the region. Human settlement and species introductions also reduce the chance of unique, surviving native species. Some local animals exist as distinct subspecies or isolated populations, but not as species found only in the Marshalls.
Explore close alternatives. Look for near-endemic or regionally restricted species in the central Pacific, endemic subspecies and island-adapted forms, and native species of conservation concern. Also consult related categories that do exist in the Marshalls: seabirds and shorebirds that breed on the atolls, coastal plants adapted to coral sands (for example, Pandanus and Scaevola types), and rich reef communities with corals and fish typical of the central Pacific. For authoritative lists, check IUCN, GBIF, BirdLife, and regional checklists.
Consider next steps. Review “near-endemic” and “native species of conservation concern” for the Marshall Islands, or compare endemics from nearby island groups (Palau, the Federated States of Micronesia, and Hawaii).
