Unfortunately, although most brown spiders are harmless, it’s difficult to tell them apart. Brown spiders all look very similarly in markings and coloration. Because of this, if you see a brown spider, it’s better to stay away. Ono, H. (2002). "New and Remarkable Spiders of the Families Liphistiidae, Argyronetidae, Pisauridae, Theridiidae and Araneidae (Arachnida) from Japan". Bulletin of the National Science Museum (Of Japan), Series A. 28 (1): 51–60. Zhou, J., Lai, J., Menda, G., Stafstrom, J.A., Miles, C.I., Hoy, R.R. and Miles, R.N., 2022. Outsourced hearing in an orb-weaving spider that uses its web as an auditory sensor. Proceedings of the National Academy of Sciences, 119(14), p.e2122789119. Once hatched, baby spiders go through several stages of growth before becoming adults. During these stages, called instars, they shed their exoskeleton multiple times as they grow bigger and stronger. After reaching adulthood, most spiders will only live for one or two years before dying off naturally due to old age or predation from other animals. Conservation and Population

Norton, Elizabeth (2013). Aspects of Ecphrastic Technique in Ovid's Metamorphoses. Newcastle upon Tyne, England: Cambridge Scholars Publishing. p.166. ISBN 978-1-4438-4271-6. The oldest known exclusively terrestrial arachnid is the trigonotarbid Palaeotarbus jerami, from about 420million years ago in the Silurian period, and had a triangular cephalothorax and segmented abdomen, as well as eight legs and a pair of pedipalps. [88] Attercopus fimbriunguis, from 386million years ago in the Devonian period, bears the earliest known silk-producing spigots, and was therefore hailed as a spider at the time of its discovery. [89] However, these spigots may have been mounted on the underside of the abdomen rather than on spinnerets, which are modified appendages and whose mobility is important in the building of webs. Hence Attercopus and the similar Permian arachnid Permarachne may not have been true spiders, and probably used silk for lining nests or producing egg cases rather than for building webs. [3] The largest known fossil spider as of 2011 is the araneid Nephila jurassica, from about 165million years ago, recorded from Daohuogo, Inner Mongolia in China. [90] Its body length is almost 25mm, (i.e., almost one inch). Even arachnologists have a hard time identifying hobo spiders, as there are many similar looking spiders and because there is great variation within the species itself.

Found only in Brazil, Peru, Ecuador, and Colombia, the orange tortoise spider is a unique type of South American orb-weaver. Like its name, this spider has a cute shell-like body that makes it look like a brightly colored tortoise! The visual acuity of some jumping spiders exceeds by a factor of ten that of dragonflies, which have by far the best vision among insects. [ citation needed] This acuity is achieved by a telephotographic series of lenses, a four-layer retina, and the ability to swivel the eyes and integrate images from different stages in the scan. [ citation needed] The downside is that the scanning and integrating processes are relatively slow. [22] Mason, Betsy (28 October 2021). "Spiders are much smarter than you think".

These spiders are part of the family Lycosidae and are found throughout North America above Mexico.They have a massive leg span of around 24cm and huge fangs, though their venom is not lethal to humans.

Spiders have been the focus of stories and mythologies of various cultures for centuries. [132] Uttu, the ancient Sumerian goddess of weaving, was envisioned as a spider spinning her web. [133] [134] According to her main myth, she resisted her father Enki's sexual advances by ensconcing herself in her web, [134] but let him in after he promised her fresh produce as a marriage gift, [134] thereby allowing him to intoxicate her with beer and rape her. [134] Enki's wife Ninhursag heard Uttu's screams and rescued her, [134] removing Enki's semen from her vagina and planting it in the ground to produce eight previously-nonexistent plants.

Some spiders use their webs for hearing, where the giant webs function as extended and reconfigurable auditory sensors.
