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

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

Two-segmented chelicerae is the ancestral condition in Acariformes, but in more derived groups they are single-segmented. And three-segmented chelicerae is the...

Atlantic Forest. The genus is characterized by the extremely modified male chelicerae and long pairs of ventral spines. It is the first fully revised endemic...

"true spiders") are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action,...

differences include the fact that Opiliones have no venom glands in their chelicerae and thus 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...

chelicerae are very diverse between species, but they are generally very long with small curved teeth without serrations. Studies on the chelicerae and...
