8.7 million species

It’s all feeling quite fanciful. Too fanciful. At this point, I can hardly fault Shufflebottom for his position. If the tables were turned, I would probably react in the same way.

Fact: Scientists estimate there are 8.7 million species on this planet. Only about 1.2 million of them are currently identified. (Read more here.) And of those catalogued, there are plenty of animals—even very large animals—that are almost never seen. (Just read this to learn more.)

There are over 7 million species still unknown, not to mention all of those that have come and gone and never had the chance to be catalogued at all! (Granted, the majority of unknown millions are not vertebrates—it’s generally acknowledged that most mammals have been catalogued.)

Question: What’s still out there, waiting to be discovered?
