No results: no species meet the strict criterion of being endemic to “Micronesia” as a single, unified region.
Note that defining endemism to the entire Micronesia region creates this empty result. Treat Micronesia as many islands and archipelagos, not one continuous landmass. Most species are endemic to a single island, a single archipelago (for example Palau, Pohnpei, Kosrae, Yap, Chuuk, the Marianas), or to a single country. Very few — and in practice none that fit strict definitions — are found only across the whole Micronesian region and nowhere else.
Recognize the technical and historical reasons behind the gap. Islands drive very local endemism, so evolution usually produces island- or archipelago-restricted species rather than region-wide endemics. Taxonomy and data also make strict regional endemism hard to prove: many records use island- or country-level ranges, some taxa are reclassified, and limited surveys leave uncertainty. Human introductions, extinctions, and sea-level changes further blur clear regional-only ranges.
Check close alternatives that are useful and real. Compile lists of species endemic to individual islands or archipelagos (birds, reptiles, plants, land snails, reef organisms). Use authoritative sources like IUCN, GBIF, and regional checklists. Explore “Endemic species of Palau,” “Endemic species of Pohnpei,” or “Micronesian island-level endemics” instead to find the species, ranges, and conservation details you are likely looking for.
