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 ).
Solpugidae is a family of solifuges or sun spiders. Solpugidae have groups of papillae on their pedipalps or sensory organs. The papillae come out of sockets that are characterized with the function of mechanoreceptor, and contact chemoreceptors, which allows them to respond to stimuli such as touch and sound.
The spider seldom initiates hunting behavior to still prey, and interrupts ongoing hunting behavior when the prey ceases to move.
