	Ricinulei
		A ricinuleid, commonly known as a "hooded tickspider", is an invertebrate animal belonging to the order Ricinulei in the class Arachnida, in the subphylum Chelicerata of the phylum Arthropoda.
		Ricinulei range from 5 to 10 mm in length.
		As of 2000, approximately 55 species of ricinulei have been described worldwide, all in a single family which contains 3 genera.

	Acari (Site not responding. Last check: 2007-10-18)
		Recently, many acarologists have concluded that mites are closely related to the arachnid order Ricinulei (Lindquist 1984, van der Hammen 1989, Evans 1992).
		According to van der Hammen, the Ricinulei and Anactinotrichida (Parasitiformes + Opilioacariformes) are sister groups and, within another lineage, the Actinotrichida (Acariformes) and the non-acarine Palpigradi also are sister groups.
		This hypothesis is based on the characters presented by Lindquist, and is in agreement with that of Weygoldt & Paulus (1979) and Schulz (1990), but not with that recently proposed by Dunlop (1996).

		Pitluga of the Adler Astronomy in Chicago has shown that whilst the secondary lines correspond to constellations only with the same probability any such lines might, the original Nazca drawings - the 500ft animals - such as the spider, correlate exactly with the movements of Orion throughout earliest prehistory.
		Pitluga, Hancock and co. also point out that the spider depicted is a member of the genus Ricinulei, clearly denoted by the shape of its body and right down to the detail of the reproductive organ on its right leg.
		But the problem is that Ricinulei is one of the rarest spider genera on Earth.

		Now the spider is a member of a known spider genus- Ricinulei.
		This spider just happens to be one of the rarest spiders in the world,so rare that it has only been found in remote and inaccessible parts of the Amazon (WATCH OUT MALCOLM).
		It was identified as a member of the rare genus Ricinulei, which is only found in the most remote and inaccessible parts of the Amazon Jungle.

	Ricinulei (hooded tick-spiders) (Site not responding. Last check: 2007-10-18)
		The Ricinulei were regarded as the most enigmatic group of the arachnids for a long time.
		Although today it is known that these animals are quite common in their limited distribution areas they were not often objectives of scientific research.
		In order to enhance the knowledge of these animals, specimens from the other two genera are needed for further research.

		Athena then changed Arachne into a spider and gave her name to the Arachnida.
		The first true spiders appeared in the Carboniferous Period and are grouped into the Ricinulei, a group of plump and primitive spiders.
		A few species of the Ricinulei survive today as "living fossils" in tropical forests.

		The class Arachnida comprises 12 living and 5 extinct orders of which eleven occur in the Afrotropical Region.
		Some orders are sensitive to pollution and habitat destruction and have traits that make them good biodiversity indicators.
		Other orders such as the Amblypygi, Palpigradi, Ricinulei and Uropygi have small ranges and many of the species are endemics and restricted to small areas.

	Nazca Lines: Introduction
		The Nazca lines and figures cover a total area of 520 square kilometres.
		This information appears to signify an advanced ancient culture at work, but fails when inspected more closely. The only similarity between the spider figure and a Ricinulei is the extended leg. Otherwise the figure could be just a common local spider. Or the same as the depiction found at the Etowah Mounds (USA).
		Many of the figures on the plain have an extra leg or pathway attached to them — all we have here is a coincidental stylisation.
