The posterior lateral (PLE) and anterior lateral eyes (ALE) provide the spider with a 360-degree survey of its surroundings. Field of vision of the ALE overlap in front of the spider. Each anterior medial eye (AME) consists of a long tube that can be moved independently to scan the area in front of the spider with high resolution.
[2] [5] The secondary eyes normally have a light-reflecting layer, the tapetum, that makes the eyes appear pale. [6] The tapetum differs considerably between spider families but can be separated into three main types: PT (primitive type), CT (canoe type), and GT (grate type). Some spiders, such as jumping spiders, have no tapetum in their ...
Phidippus princeps is a species of jumping spider found in Canada and the eastern United States. These jumping spiders' vision exceeds by a factor of ten than that of a dragonfly's, which have the best vision among insects. [1] Feeding
This dynamic adjustment is a means of compensation for the narrowness of the static field of vision. Movement of the retina in jumping spiders is analogous to the way many vertebrates, such as primates, move their entire eyes to focus images of interest onto their fovea centralis. In jumping spiders with a translucent carapace, such movements ...
Euophrys leipoldti or the Karoo Euophrys Jumping Spider is a species of jumping spider in the genus Euophrys that is endemic to South Africa. It lives in karoo and succulent karoo. The female was first described in 1903 by George and Elizabeth Peckham and the male in 2014 by Wanda Wesołowska , Galina Azarkina and Anthony Russell-Smith.
Like other jumping spiders, T. planiceps relies on their very acute eyesight for hunting. The anterior median eyes are the primary eyes used for capture of stationary prey while the anterior lateral eyes are the main eyes used in chasing Both sets of eyes can be coordinated to enable switching from one hunting type to the other.

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".
