How many animals live in Madagascar?

Madagascar has an unusual mix of wildlife. For example, the island does not have apes, monkeys, elephants, zebras, giraffes, lions, hyenas, rhinos, antelopes, buffalo, or camels that you might expect to find in Africa, but it does have lemurs, tenrecs, boa constrictors, iguanas, and other creatures.

So it isn't very clear how much animal live in Madagascar ;-)
