From article: "Sunspiders are extremely voracious, and the largest forms can kill small vertebrates. The chelicerae (first pair of appendages) are large toothed, jawlike pincers, and the leglike pedipalps (second pair of appendages) have suctorial tips for seizing prey. Unique racket-shaped organs (malleoli) on the hindmost legs may be sensory."
"Solifugids are fast running, nocturnal arachnids that resemble something intermediate between a scorpion and a spider, thus the alternate common name, sun spider."
