A new report released yesterday by the Public Library of Science’s online journal, PLoS Biology, estimates that the Earth is home to almost 8.8 million species, but mankind has only discovered approximately 1.9 million of them.

A few of the reasons for this can be that the animals live in places that are hard to access, like deep oceans and remote rainforests, or that they are so small that we can easily miss them. Judging from these pictures, we should be looking in our coin purses!
