Jumping spiders are a group of spiders that constitute the family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, [1] making it the largest family of spiders at 13% of all species. [2] Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and ...
Most spiders' eyes can detect little more than brightness and motion, so vision plays only a minor role in behaviour. However some species, such as jumping spiders, wolf spiders, and deinopids, have more developed eyes which they use in hunting and courtship. [2]
Phidippus audax are commonly referred to as "bold jumping spiders" or "bold jumpers". [8] The species name, audax, is a Latin adjective meaning "audacious" or "bold".

The other six are secondary eyes, positioned along the sides of the carapace and acting mainly as movement detectors.

Several families of hunting spiders, such as jumping spiders and wolf spiders, have fair to excellent vision. The main pair of eyes in jumping spiders even sees in color. [9] Net-casting spiders of genus Deinopis have their posterior median eyes enlarged into large forward-facing compound lenses. These eyes have a wide field of view and are ...
