Topping the list of rare and exotic species are the world-famous big-eyed, pointy-nosed primates - lemurs
Lemurs vary greatly in size, appearance and behaviour - from the tiny pygmy mouse lemur to the large white and black panda-looking indri.
There is the sifaka, known as the "dancing" lemur because of its unusual ballet-like movement when sashaying across open areas, while the ring-tailed lemur is easily recognized by its long, black and white ringed tail.
Some live in the country's moist, tropical rainforests
, while others live in dry forests
and desert areas
As diverse as they are, lemurs have one thing in common - they are all in some way in danger of becoming extinct.
