With the exception of the condor, all other animals depicted on the Nazca plateau have nothing to do with this place. The monkey, the whale, the hummingbird, the pelican, the spider, all of them.

(Ok, perhaps with the exception of the llama)

The spider catches your attention, not only because of the complexity of the scheme but also because it depicts a spider of the order Ricinulei, a rather rare spider, found (nowadays) in the deeps of the Amazon forest.

The interesting thing with the spider, though, is the extension you can see on the right foot. On the first view, you might think that “there must be something wrong here”. But, this Ricinulei spider, has its reproduction system on its right leg! Exactly where the extension is placed!

And, of course, this is something that can be viewed only through a microscope.

So, somehow, these ancient guys (and not the Nazcas) could fly somehow (so they can manage the whole design and, of course, see the actual results) and also had technology similar to a modern microscope, to be in a position to find out how this specific spider reproduce.
