What is a Spider?
A spider is a predatory invertebrate animal with eight legs and two body parts, and no wings. They are often confused as being insects, but all spiders have 8 legs, unlike insects which have 6.
Spiders usually have silk-spinning organs at the back end of the body which they use to spin silk to construct cocoons for eggs or traps and webs for prey.
A spider is any member of the arachnid order Araneae, an order divided into three sub-orders: the Mygalomorphae (primitive spiders), the Araneomorphae (modern spiders) and the Mesothelae, which contains the Family Liphistiidae, containing rarely seen burrowing spiders from Asia.
All spiders are carnivores. They eat other species of arthropods including mites, crustaceans, mice, skinks and even other spiders.
The study of spiders is known as arachnology, although it is often included in the more general term entomology.

许多不同种类的蜘蛛都被称作圆蜘蛛，因为它们织出的网都呈圆形或环状。蜘蛛从它身体下侧被称为"吐丝器"的器官中吐出丝来。
它先织出长椭圆形的框架，然后从中间开始展开丝线，就像给轮子上辐条一样。
紧接着，它再将一圈丝从里到外地排上去，然后又将另一圈丝又从反方向织上去。这种丝有粘性。当它织上去后，蜘蛛就切掉前一圈丝，然后躲起来等待猎物。
它可以从丝的震动感知到有昆虫被网捕获了。接着，它便冲上前，用丝把正在挣扎的猎物捆起来，再用毒液将其麻痹。
Many different types spiders all are called the round spider, becausethey weave the net all assumes the circular or ring-like. The spideris called from its body breast " Spinning " In the organputs out the silk.
It first weaves the ellipse the frame, then starts from among tolaunch the silk thread, the picture gives on the wheel the spoke stripto be same.
Is following closely, it inside and out stands in line again a silk,then weaves another silk from the reversed direction. This kind ofsilk has the coherency. After it weaves, the spider cuts away thepreceding silk, then hides the waiting game.
It could to have the insect from the silk vibration sensation to catchby the net. After that, it then flushes goes forward, the game whichstruggles is bundling with the silk, again uses the venom itsparalysis.

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. As of November 2015, at least 45,700 spider species, and 113 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel. Unlike insects, spiders do not have antennae. In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax. Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure.
