Most spiders have eight SIMPLE eyes (to match their eight legs?)

These eyes are known as Ocelli and are arrange on the top of its head.

The spider can see in all the eight directions at the same time.

(Better equipped than Brahma who can see only in four directions).

The species like the jumping spider stalks and pounces of its prey

-rather than wait till it comes closer.

The two eyes in the front are much better developed than the remaining six eyes.

This helps the spider gauge the distance accurately for its final pounce on its target.
