No animal species are known to occur only inside Eritrea’s political borders.
Note the phrase “only found in Eritrea” creates an empty result because animal ranges rarely stop at a country line. Eritrea shares habitats with neighboring countries and the Red Sea. Most species there live across the Horn of Africa or in the wider Red Sea region, so none are recorded as strict country endemics.
Understand the technical reasons behind this outcome. Political borders are human constructs; ecosystems and animal populations cross them freely. Eritrea’s fauna overlaps with Ethiopia, Sudan, Djibouti and the Red Sea fauna. Also, species lists change with new surveys and taxonomic work, so a species might later be split or lumped. Close matches include Red Sea endemics (animals found only in the Red Sea, such as the two‑band clownfish, Amphiprion bicinctus) and Horn of Africa endemics that occur in Eritrea plus neighboring countries. Endemic subspecies and island or marine endemics around the Dahlak Archipelago also come close to the strict definition.
Explore related, useful categories instead of strict country endemics: animals of Eritrea (complete species lists), species endemic to the Horn of Africa, Red Sea endemics, and endemic subspecies or island fauna. Consult authoritative sources (IUCN, BirdLife, GBIF, Reptile Database) for verified ranges and conservation status.
