When it comes to "discovering" new species of animals, I think it's more about having found where they've been hiding themselves from humanity and less about discovering brand new species.
I mean, most of the animals in this gallery look like the result of genetic evolution and adaptation, not some brand spanking new little critter.
But they are cute, and great fun to read about, considering that they're so rare to see in nature. So take a look at this gallery and see what the animal guides were missing up until last year.
