Spiders belong to arthropods. The body of a spider is divided into a head, chest, and abdomen, which are connected by a slender ventral stalk; The head has a pair of claws in front of the head, and the end of the claws is the venomous teeth of the venom gland duct; There are four pairs of feet on both sides of the chest, with hard claws at the tips of the feet; Spiders have single eyes, as well as eight eyes, six eyes, and four eyes. Wang Anshi's "Zishuo" records that a web was set up on one side, and when an object touched it, it was executed, hence the name "Spider". Spiders are distributed throughout China, mostly inhabiting eaves, corners of walls, and between trees, forming wheel shaped webs. Spiders have a diverse diet, mainly feeding on insects such as flies. They are tolerant to hunger, have strong reproductive ability, and have a long lifespan.
