What is "solifugae"

Solifugae \So*lif"u*g[ae]\, n. pl. [NL., from L. solifuga (better solipuga), a kind of venomous ant, or spider.] (Zo["o]l.) A division of arachnids having large, powerful fangs and a segmented abdomen; -- called also Solpugidea, and Solpugides.

The Solifugae are an order of animals in the class Arachnida known variously as camel spiders, wind scorpions, sun spiders, or solifuges. The order includes more than 1,000 described species in about 153 genera. Despite the common names, they are neither true scorpions (order Scorpiones) nor true spiders (order Araneae) – though they are more closely related to scorpions than to spiders. Much like a spider, the body of a solifugid has two tagmata: an opisthosoma (abdomen) behind the prosoma (that is, in effect, a combined head and thorax). At the front end, the prosoma bears two chelicerae that, in most species, are conspicuously large. The chelicerae serve as jaws and in many species also are used for stridulation. Unlike scorpions, solifugids do not have a third tagma that forms a "tail". Most species of Solifugae live in dry climates and feed opportunistically on ground-dwelling arthropods and other small animals. The largest species grow to a length of , including legs. A number of urban legends exaggerate the size and speed of the Solifugae, and their potential danger to humans, which is negligible.
