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 ...
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 ...
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).
"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]
"Squared-off" cephalothorax and eye pattern of jumping spiders. Although other spiders can also jump, salticids including Portia fimbriata have significantly better vision than other spiders, [12]: 521 [13] and their main eyes are more acute in daylight than a cat's and 10 times more acute than a dragonfly's.

The genera Lyssomanes, Chinoscopus, Hindumanes, and Sumakuru make up the Lyssomaninae, which is one of the six deeply-diverging subfamilies of jumping spiders. [4] They are long-legged, with translucent bodies frequently green or yellow. They resemble lynx spiders, except that they have large anterior median eyes. [citation needed]
