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 ...
Basic arrangement of spider eyes, viewed from above. Most spiders have eight eyes, which tend to be arranged into two rows of four eyes on the head region. The eyes can be categorised by their location and are divided into the anterior median eyes (AME), anterior lateral eyes (ALE), posterior median eyes (PME), and posterior lateral eyes (PLE).
Eye pattern of jumping spiders on "squared-off" cephalothorax. Jumping spiders have eight eyes, the two large ones in the centre-and-front position (the anterior-median eyes, also called "principal eyes" [6]: 51 ) providing acute vision and housed in tubes in the head. The other six are secondary eyes, positioned along the sides of the carapace ...
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". [8] This name was first used to describe the species by French arachnologist Nicholas Marcellus Hentz, who described the spider as being, "very bold, often jumping on the hand which threatens it". [9]
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 able to gather available light more efficiently than the eyes of cats and owls.
The spider's mouthparts, including its chelicerae, labium and maxillae are generally orange-brown. [12] The male spider's abdomen is between 1.88 and 2.75 mm (0.07 and 0.11 in) long and 1.24 and 2 mm (0.05 and 0.08 in) wide. It is generally dark grey on top but its pattern varies between individual spiders.

"Squared-off" cephalothorax and eye pattern of jumping spiders. Jumping spiders have significantly better vision than other spiders, [5]: 521 [6] much more acute than that of other animals of similar size, [7] and clearer in daylight than a cat's and 10 times more acute than a dragonfly's. [2]
