They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms [ 1 ] which is reflected in their ...
This enables spiders with scopulae to climb even sheer, smooth surfaces such as glass. The adhesion is so great that the spider could grip using this force and support 170 times its own weight. Possible physical mechanisms may include capillary, electrostatic, viscous, or Van der Waals force. (Niederegger et al 2002; Betz and Kölsch, 2004) [2]
Solifugae is an order of arachnids known variously as solifuges, sun spiders, camel spiders, and wind scorpions. The order includes more than 1,000 described species in about 147 genera . Despite the common names, they are neither true scorpions (order Scorpiones) nor true spiders (order Araneae ).
Most ballooning journeys end after just a few meters of travel, although depending on the spider's mass and posture, [16] a spider might be taken up into a jet stream. The trajectory further depends on the convection air currents and the drag of the silk and parachute to float and travel high up into the upper atmosphere .

Pirate spiders, members of the family Mimetidae, are araneomorph spiders which typically feed on other spiders. The family Mimetidae contains roughly 200 species divided among 12 genera, of which Mimetus and Ero are the most common. Mimetids are usually yellow and brown and are usually 3 to 7 millimetres (1 ⁄ 8 to 1 ⁄ 4 in) long. Mimetids ...
A male Eresus sandaliatus. Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders.Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
