Close-up of the thorax of the spider showing the precision of line placement and design - while each curve is not exactly the same, it is clear that I high degree of precision was used in measuring the design, with great care in the construction

Close-up of the Nazca spider's head showing a high degree of symmetry - you can also see that the rough line that crosses the left side, not only is crude in comparison, but was also created after the spider, since it cuts through the spider's design

This image is of the front right legs - showing the parallel designs, spacing, and alignment of the bends - no doubt that this was a well planned construction

While not all the leg pairs have their joints in perfect parallel, it appears that that was the design goal

Close-up of the left rear feet - showing much more well rounded constant curves that most Nazca animal figures

The spider is probably one of the two best know, most iconic, of the Nazca figures

Like some other Nazca animal symbols, the spider has an entry line and an exit line, permitting a walk along the entire object without crossing a line

Close up of the parrots head shows that it has more in common with an ant, particularly in that the design appears to have six legs

Could this actually be a stylized ant (with six legs) with one antennae on the left?  Assume that you are looking at the insect from overhead, instead of a beak, the mouth parts are mandibles.

Only four legs are shown, but the animal's body is cut off by the runway - further adding support for the ant definition - additionally, no Nazca bird has wings of this design

This geoglyph has been substantially destroyed by the creation of the runway through it.  What the exact design was of this figure is now impossible know.
