This is a wall-like spider, they have very large eyes on their heads that are very unusual in structure with a boomerang-shaped corneal layer (V-shaped) that helps it distinguish images with high resolution, even see Different ultraviolet and colorful rays, eyes are considered their fixed 'lenses'.

Spider 8 eyes with 2 large eyes above the head.

The other 3 eyes are 2 pairs on both sides, and one pair is behind, although they are considered 'auxiliary eyes' but still have very good eyesight, especially in detecting moving objects. What is special is that wall spiders not only have sharp eyesight but also have the ability to "communicate" and are very curious about people and what's around it.

Elizabeth Jakob, a professor and researcher in psychology at the University of Massachusetts Amherst (USA), said that unlike the 'black widow' (Black Widow) or the recluse brown spider (Brown Recluse) is afraid of humans and species. Wall spiders are very bold. She said that this spider might think a large object like a human is a prey target, however, it is completely harmless.

Reportedly, Jakob and her colleagues published a video of the spider wall and did some other experiments by trying to create a vision monitor to learn more about the working principle of the corneal system. eyes in the front eyes of this spider.
