Out of all the countries on Earth, only seventeen fall under the category of megadiverse. 

South Africa, due its plethora of flora and fauna is lucky enough to also be included under this prestigious list. South Africa is home to about 10% of the world’s plant species, with nearly 20 000 different types. Because SA is relatively small compared to the others on the list, it is in fact the world’s most biodiverse when size is taken into account.
