	Opiliones are delicate, shy forms, and are among the largest of arachnids in woodlands [2].		Opiliones have been in evolutionary stasis since the early Devonian period.[me] They are delicate, shy forms, and are among the largest of arachnids in woodlands [2]. Like other arachnids, they possess 8 legs, 2 pedipalps and 2 chelicerae.[8]
	'''Opiliones''' can be differentiated from spiders by looking closely at what appears to be one body segment, but is actually two fused segments, which is ~~consitent~~ with spiders. Daddy long-legs do not possess silk glands, and can not spin webs. Unlike spiders, harvest men lack venom glands associated with their chelicerae. True of all arachnids, fertilization is by direct contact with female. Males of most taxa possess a penis, which is also referred to as a pene, or an aedagus. [3]		'''Opiliones''' can be differentiated from spiders by looking closely at what appears to be one body segment, but is actually two fused segments, which is consistent with spiders. Daddy long-legs do not possess silk glands, and can not spin webs. Unlike spiders, harvest men lack venom glands associated with their chelicerae. True of all arachnids, fertilization is by direct contact with female. Males of most taxa possess a penis, which is also referred to as a pene, or an aedagus. [3] Opiliones unlike spiders do not possess a book lung, instead their respiratory system is trachial, similar to [[acari]] and [[solifugea]].[8]

	Harvest men are known for their exceptionally long walking legs compared to body size, although some species do have shorter legs. In more advanced species of harvest men, the first five abdominal segments are often fused into a dorsal shield called the scutum, which is normally fused with the carapace. Sometimes this shield is only present in males.They have a second pair of legs that are longer than the others and work as antennae. This can be hard to see in short-legged species.

	Typical body lengths do not exceed 7 millimeters, with some species smaller than one millimeter. The largest species ''Trogulus Torosus'' can reach a length of 22 millimeters. [4] Leg spans are much larger and some species can exceed 160 ~~millimeter~~. [1]		Typical body lengths do not exceed 7 millimeters, with some species smaller than one millimeter.

			. Most species tend to be nocturnal, although a number of diurnal species have been identified. Some of the predaceous Opiliones are also diurnal, but most are known to be crepuscular.[2] Opiliones feed by ingesting large chunks or particles of prey rather than predigesting or liquefying their prey.[8]

	== Reproduction ==		== Reproduction ==

	Although parthenogenic species do occur, most harvest men reproduce sexually. Mating involves direct copulation. The males of some species offer a secretion from their chelicerae to the female before copulation. Sometimes the male guards the female after sex.

	Although ~~daddy~~ harvest men are a fascinating group of arachnids, the dramatic increase in environmental disturbances around the world, especially in tropical regions, may have driven many species to extinction even before the formal descriptions by taxonomists. Human activities including pesticide use, forestry operations, air and soil pollution, fire, and even the introduction of domestic animals have a tremendous impact on the habitats they depend on. All the formerly considered endangered were cave dwellers who are particularly sensitive to disturbances of habitat.

	Opiliones are delicate, shy forms, and are among the largest of arachnids in woodlands [2].		Opiliones are delicate, shy forms, and are among the largest of arachnids in woodlands [2].
	Opiliones can be differentiated from spiders by looking closely at what appears to be one body segment, but is actually two fused segments. Daddy long-legs do not possess silk glands, and can not spin webs. Unlike spiders, harvest men lack venom glands associated with their chelicerae. True of all arachnids, fertilization is by direct contact with female. Males of most taxa possess a penis, which is also referred to as a pene, or an aedagus.

	Harvest men are known for their exceptionally long walking legs compared to body size, although some species do have shorter legs. In more advanced species of harvest men, the first five abdominal segments are often fused into a dorsal shield called the scutum, which is normally fused with the carapace. Sometimes this shield is only present in males.They have a second pair of legs that are longer than the others and work as antennae. This can be hard to see in short-legged species.

	Laniatores are by far the largest suborder with >4100 species).[3] These stout, spiny Opiliones are typically short legged with hard plates, with many reaching large sizes. Most species in this sub-order depend on warm moist habitats. Given that majority of Laniatores prefer the tropic climate, it is not uncommon to find them in temperate forests as well.

	These are the Opiliones familiar to Europeans and Americans that have earned them the order the name daddy long legs. Their legs are often very thin and long. Several of the tropical species ex. Gagrellinae, may have metallic shines, intricate honeycomb patterns of vascular tissues, and striped/dotted multicolored hues of blue, red, green, yellow.

	These Opiliones are smaller than the Euponoi members and resemble minute Acari. Cyphophthalmi are the least studied sub-order with only 200 species, but this is thought to be a major underestimate. [6] Their small size and wide distribution have contributed to their lack of study. Cyphophthalmi species can tolerate many climate conditions and are found on all the continents except ~~Anartica~~.		These Opiliones are smaller than the Euponoi members and resemble minute Acari.
