Spider, also known as Networm, Flat Spider, Round Spider, Octopus, Xizi and Bos. Most of them feed on insects, other spiders and multi-legged animals, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive at close range to catch prey within 30 cm.

Generally speaking, spiders are insects, but not scorpions and centipedes. Because the basic characteristics of insects are head, chest and abdomen, two pairs of wings and six feet.

Experts from the Institute of Gene Biology of the Russian Academy of Sciences are actively studying the use of spider silk to make high-strength materials. There is a cluster of spinnerets behind the spider's abdomen, which passes through the silk glands in the body. Protein mucus secreted by this gland can condense into extremely strong spider silk in the air. The material woven by spider silk with a certain thickness is 9 times higher than that of steel with the same thickness, and its elasticity is 2 times higher than that of other most elastic synthetic materials.

After further processing, spider silk material can be used to make light body armor, parachutes, protective materials for weapons and equipment, wheel tires, plastic surgery instruments and high-strength fishing nets.
