All spiders possess photosensitive microvilli which have the capacity to be sensitive to the polarisation of light, as they preferentially absorb light oscillating parallel to their long axis. These microvilli are arranged orthogonally in the eyes of several families, including jumping spiders , wolf spiders , and nursery web spiders .
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.

"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.
