Armored harvestmen in Laniatores can often use their modified morphology as weapons. Other differences include the fact that Opiliones have no venom glands in their chelicerae and therefore pose no danger to humans.

A survey of antipredator defenses. Well-preserved fossils have been found in the million-year-old Rhynie cherts of Scotland, and million-year-old rocks in France, which look surprisingly modern, indicating that their basic body shape developed very early on,  and, at least in some taxa, has changed little since that time. Leave it all behind: a taxonomic perspective of autotomy in invertebrates. Such a broad range is unusual in other arachnids, which are typically pure predators. For other arthropods called "daddy longlegs", see Daddy longlegs disambiguation. As a consequence, most known fossils have been preserved within amber.
