Wind Scorpions Control
Although Solifugae appear to have ten legs, they actually have only eight, as other arachnids do. The first pair of appendages are not legs, but pedipalps. The pedipalps of Solifugae function partly as sense organs similar to insects' antennae, and partly in locomotion, feeding and fighting. In normal locomotion they do not quite touch the ground but are held out to detect obstacles and prey. In that motion, they look like an extra pair of legs.
Solifugae are the subject of many urban legends and exaggeration about their size, speed, behavior, appetite, and lethality. They are fast on land compared to other invertebrates. The fastest can run perhaps (1O mph) for a short distance. Members of this arachnida have no venom and do not spin webs.
The greatest threat they pose to humans, however, is their defense bite when handled. There is essentially no chance of death directly caused by the bite; however, due to the strong muscles of their chelicerae, they can produce a large, ragged wound that is prone to infection.
