These numbers are not accurate, as accurate number of animal species on earth has yet to be discovered. Currently it looks like less than 3% of the known species of animals on earth are vertebrates (have back bones). There are around 50 000 species of vertebrates, most of which are fish. Most animals are invertebrates, and most of those are insects.
