Not Spiders, Not Scorpions: The Arachnid Misclassified as a Desert Menace?

10 Cool Facts about Camel Spiders | Pet Tarantulas · 4:07 · Video: Howcast · Watch at the source

In short: These creatures, often called camel spiders or wind scorpions, generate wild myths of attacking humans or consuming camels. Yet, their true nature—their classification, size, and feeding methods—are far more complex and fascinating than popular legend suggests.

The popular perception of camel spiders is heavily colored by misinformation, particularly following the Iraq conflict. Many legends depicted them as massive, bloodthirsty predators, but multiple sources confirm these tales are untrue. For instance, claims that they can be three feet long are false; in reality, a large specimen rarely exceeds six inches, and they do not disembowel camels or attack sleeping soldiers. Furthermore, while they are often associated with the Middle East, they are also found in areas like Arizona and New Mexico in the United States.

Taxonomically, the confusion is significant. They are not spiders, nor are they scorpions, despite the common names. They belong to the order Solifugae, which translates from Latin to 'those who flee from the sun.' While they are correctly placed in the class Arachnida, they are distinct from true spiders. The scientific literature suggests there are over 1,000 species globally, with estimates reaching around 1,100 species, and they are found in deserts worldwide, excluding Australia and Antarctica. Evolutionary biologists have suggested links between solifugids and pseudoscorpions, or even mites.

Their anatomy is also frequently misunderstood. Although they may appear to possess ten legs, they possess eight. The two elongated appendages visible at the front are pedipalps, which function as sensory organs, a feature shared with tarantulas but distinct from them. When feeding, they utilize powerful jaws, which can measure up to one-third of their body length. They do not merely bite; they use a sawing or chopping motion to seize prey—which includes insects, rodents, lizards, and small birds—and then use digestive fluids to liquefy the flesh before sucking the remains into their stomachs.

Regarding their biology, they are carnivorous predators. While their bite is noted as painful, they are not considered venomous. In the wild, their average lifespan is estimated to be up to one year. For captive care, they are described as requiring specialized accommodations, and it is noted that all specimens available are wild-caught, meaning any pet owner would acquire an animal of undetermined age.
