Question…how many of you now reading this blog have purchased one or all of my 12-volume series, “Visit the Zoo” as of today? Well, those of you who have will know that I have described the status of each of the 120 animals in my books. That’s the status as to how close they are to extinction or how they are currently flourishing.

Here are some astonishing facts: Every DAY approximately 100 animal species go extinct…kaput…adios…goodbye forever. Extinction may be due to loss of habitat, encroachment of the human species or simply coming to the end of their evolutionary timetable. However, scientists estimate there are approximately 8.3 million species that roam, fly, crawl, swim on or burrow in to Planet Earth. Even better news is that approximately 15,000 new species are discovered each year. And considering how much of our own planet hasn’t been studied in detail, the number of undiscovered species could be very large. But those undiscovered species are probably the smaller animals, we know about most of the big ones. And this planet has seen some extremely large animals populate the Earth in the past.

I saw this list somewhere on the web a couple of days ago of the largest animals ever to roam the Earth. In case you missed it, I thought I would pass it along to you. By the way, consider  your own height and weight as you read this list:
