Original caption: Diagram of the approximate visual fields of Phidippus as viewed from above, showing the eyes and their respective optic nerves connected to the prosomal CNS. The posterior lateral (PLE) and anterior lateral eyes (ALE) provide the spider with a 360-degree survey of its surroundings.
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).
Also, brown recluse spiders have six eyes, instead of the eight that many other spiders have. ... Jumping spider. What they look like: There are more than 300 species of these, and they all look a ...
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 ...
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. [6]
In hunting or jumping spiders, for example, a forward-facing pair possesses the best resolution (and even some telescopic ability) to help spot prey from a distance. Nocturnal spiders' eyes are very sensitive in low light levels and are large to capture more light, equivalent to f/0.58 in the rufous net-casting spider. [8]
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]
