How many species of rabbits are in the world?

Well you see, America and Europe vary with recognized breeds. There are 47

accepted rabbit breeds in America there might be more or less in Britain. But another thing is, there are many people that like to experiment to either try to make a new breed or accidents happen, so those mixes end up getting sold to the public as pets so you might think there are hundreds but there aren't. Hares are considered a rabbit. If you want to know all of the accepted official breeds of rabbit or cavy(which is a guinea pig) you can go here:
