Species Naming (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Living creatures are classified into families, genera and species. To date, approximately 1.9 million species have been discovered and named. This number is still an estimate as so far there is no central registration of species, although efforts are underway to establish such a species register. The actual number of species existing on earth is not known and this figure has been very roughly estimated at between 5 and 200 million.
