Question is simple - in your opinion, which of the 7 is the best continent for mammals?
What do you mean by your question, "best continent for mammals"?
Which continent has the most mammal species? Which has the "best" species? Which is the best for seeing the most species in the wild? Which is the easiest to see species in the wild?
There are a load of variables in the question.
If you are defining the best continent in terms of mammal biodiversity then I believe it would be North America and in country specific terms Mexico which would have the highest rate of mammal species.
Indonesia has the most species, by far, and the most unique species. Mexico is generally ranked 5th, after Australia, Madagascar, and your own Brazil![]()
Yes it seems that you are right, I remember when Mexico was ranked 1st but it appears that it has dropped a few places now.
Still 5th place for mammal biodiversity is not too bad for a country but of course the challenge is to conserve that incredible biodiversity.
It seems that none of the top 5 megadiverse countries are doing as well as they could with conserving their mammalian biodiversity.
It probably dropped as more species have been discovered in the others; Mexico is much easier to explore, and has had a lot more explorers! Same with Australia.
