Madagascar is one of the most biologically diverse regions on Earth. It is the fourth largest island globally, spanning approximately 600,000 square kilometers, akin to the size of Alaska. The island is situated about 300 mil
es southeast of Africa, and its geographical isolation has led to a unique evolutionary path. Madagascar separated from Africa around 180 million years ago and from the Indian subcontinent about 90 million years ago.
Since then, its flora and fauna have evolved in isolation, resulting in a stunning array of life forms not found anywhere else.
The island is renowned for its impressive plant and animal life. Madagascar hosts nearly 15,000 plant species, including the distinctive baobab tree. Its fauna is equally remarkable, with around 90% of its animal species being endemic.
Among these are the famous ring-tailed lemurs, which are just one of over 100 lemur species that inhabit the island. The extinct giant lemurs, such as Archaeoindris, once roamed alongside other colossal creatures like elephant birds and giant tortoises.
Madagascar’s diverse wildlife extends beyond lemurs. The island is home to an array of fascinating creatures, including the Fossa—a cat-like predator with an ambiguous evolutionary background.
Its diet includes lemurs, aye-ayes (a lemur with long fingers and large eyes), giant jumping rats, and the tenrec, a small spiny mammal.
The island’s ecosystems also Support numerous bird species, reptiles, and strikingly colored amphibians and insects. The island’s isolation has fostered an evolutionary laboratory, allowing unique and varied life forms to thrive.
