The sand cat's ecological requirements are still poorly understood, as only a few in-depth studies targeting wild sand cat populations have been conducted.įelis margarita was the scientific name proposed by Victor Loche in 1858 who first described a sand cat specimen found in the area of "Négonça" in the northern Algerian Sahara. In spring, the female gives birth to two to three kittens, which become sexually mature around the age of one year. It also kills and consumes venomous snakes. It moves 5.4 km (3.4 mi) on average at night in search of small rodents and birds. The sand cat usually rests in underground dens during the day and hunts at night. Due to its wide distribution and large population, it is listed as Least Concern on the IUCN Red List. In the early 1970s, sand cats were caught in southwestern Pakistan and exported to zoos worldwide. It is discontinuously distributed in the deserts of the Arabian Peninsula and the Middle East. The large gap between these two regions of its global range was partially closed in 1948, when a sand cat skin was found in an oasis of the Rub' al Khali in Oman. In Central Asia, it was first recorded in the Karakum Desert in 1925. To date, it has been recorded in several disjunct locations in Western Sahara, Morocco, Algeria, Niger, Chad, Egypt, the Arabian Peninsula and the Middle East. The first sand cat known to scientists was discovered in the Algerian Sahara and described in 1858. The long hair covering the soles of its paws insulates its pads against the extremely hot and cold temperatures in deserts. Its 5–7 cm (2.0–2.8 in) short ears are set low on the sides of the head, aiding detection of prey moving underground. With its sandy to light grey fur, it is well camouflaged in a desert environment. The sand cat ( Felis margarita) is a small wild cat that inhabits sandy and stony deserts far from water sources. Otocolobus margarita Heptner and Dementiev, 1937.If you print directly from this page, the cabochon and wire gauge sizes may not print at the right size. OD = 7.04mm for an 18-gauge jump ring with a 5mm ID. So using the example of an 18-gauge jump ring made around a 5mm dowel, remembering that 18-gauge is 1.02 mm: Inner Diameter = OD - (wire gauge * 2) To find the Outer Diameter (OD) If you know either the ID or the OD as well as the gauge, you can find your missing measurement. Some patterns call for jump rings measured in OD, some in ID. For example, if you made your own jump rings from 18-gauge wire around a 5mm dowel, the Inner Diameter is 5mm, the gauge is 18-gauge (or 1.02mm, found in the chart above). Jump rings are typically measured by their Inner Diameter, Outer diameter, and wire gauge. Jump Rings Inner Diameter (ID) & Outer Diameter (OD) Make sure in your Print dialog box that the document prints at 100%, and does not scale it to fit your paper size. Please download this chart before printing it to ensure it prints to scale. Use this chart to determine what wire to use with beads and more! Please note, this is not to-scale on a monitor. Here's a chart with the AWG Gauge (the gauge you're used to seeing, like 22-gauge), how wide that wire is in inches, how wide it is in millimeters, and approximately how large that is. All wire begins round, so it is the most common shape.Īs you can see, the standard diameter and gauge of half round wire is measured across the flat part of the wire. Not every wire is available in each shape and gauge the boxes left blank in the chart below indicate that we do not usually stock that gauge in that shape. 's jewelry wire is measured according to AWG standards. Each strand may vary slightly by a few beads in either direction. There are about 67 beads in a strand of 16" 6mm beads. On wirejewelry, most of our strands are 16" long, or 406.4mm.ĭivide the strand measurement by the size of the bead.
