There is nowhere on Earth like Madagascar for wildlife. Cut off from every continent for tens of millions of years, it evolved a world entirely its own: predators that aren’t cats, primates found in no other forest, plants that hunt and giants that vanished. This is your map to why the island is the planet’s strangest nature destination — and where to read each story.

An island built for evolution

It all flows from one fact: Madagascar has been an isolated island for about 88 million years, since it split from the supercontinent Gondwana. That solitude let life here branch into forms found nowhere else — over 90% of its mammals and reptiles are endemic.

The cast of characters

At the top is the fossa, a predator that looks like a cat but isn’t. Below it live the lemurs, so human-like that many are sacred. In the trees cling half the world’s chameleon species, from a reptile the size of a matchstick to one as long as your arm. And the oddities keep coming: the giant comet moth that hatches without a mouth, carnivorous pitcher plants, and the elephant bird, the heaviest bird that ever lived — now extinct.

Plants as strange as the animals

The flora is just as extraordinary: the upside-down baobabs, the fan-shaped traveller’s palm, and the alien spiny desert of octopus trees. Even the land itself grows strange, as in the stone forest of the Tsingy.
