Which island country is home to all wild lemur species?

Madagascar is the island country home to all wild lemur species.

Lemurs are wet-nosed primates endemic to Madagascar, meaning wild populations naturally occur nowhere else. Their ancestors reached the island millions of years ago, probably by dispersing from mainland Africa, and then diversified in isolation. That evolutionary separation produced an extraordinary range of forms, from tiny mouse lemurs to the much larger indri.

Modern lemurs occupy forests, dry woodlands, wetlands, and some scrubby habitats across Madagascar. They include ring-tailed lemurs, sifakas, ruffed lemurs, sportive lemurs, mouse lemurs, and the aye-aye. Taxonomists recognize roughly 100 living species or subspecies under some classifications, although the exact total changes as genetic research and species debates continue.

New Guinea, Borneo, and Sri Lanka also have distinctive primates, but none has wild lemurs. Madagascar’s isolation created its remarkable endemism, yet it also makes the animals vulnerable: habitat loss, hunting, and climate pressures threaten many species. At least 17 giant lemur species disappeared after humans arrived on the island about 2,000 years ago.
