The chelicerae (/kəˈlɪsəriː/) are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders...

the Solifugae are their large chelicerae, which in many species are longer than the prosoma. Each of the two chelicerae has two articles (segments, parts...

except that mites have lost a visible division between these sections. The chelicerae, which give the group its name, are the only appendages that appear before...

ticks have a range of chelicerae. Carnivores have chelicerae that tear and crush prey, whereas herbivores can have chelicerae that are modified for piercing...

from other groups in several features, especially in the chelicerae and the telson. The chelicerae of the Pterygotidae are enlarged and robust, clearly adapted...

the abdomen and cephalothorax is often poorly defined. Harvestmen have chelicerae, pedipalps and four pairs of legs. Harvestmen were traditionally thought...

snakes. The eight legs, the two chelicerae with their fangs, and the pedipalps are attached to the prosoma. The chelicerae are two double-segmented appendages...

differences include the fact that Opiliones have no venom glands in their chelicerae, so pose no danger to humans. They also have no silk glands and therefore...

Spiders (order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude...

abdomen, sometimes dark grey. Notably, they have disproportionately large chelicerae for a spider of this size. Dysdera crocata is difficult to distinguish...
