What kind of animal is a spider? How many categories are there?
There are many kinds of spiders. There are more than 40,000 kinds of spiders in nature. These spiders can be roughly divided into three types: safari spiders, cobwebs spiders and cave spiders. The first kind will forage everywhere, and the second kind will wait for rabbits after weaving a net. Most people keep the third kind as pets: cave spiders. They like to hide in sand or holes and make a net at the hole. The net itself is not sticky, and it is purely used to sense the size of prey and hunt.

Spider habits

(a) the corpse solution:

When spiders hunt, they paralyze each other with their fangs, secrete saliva to dissolve their prey, and then suck it slowly, without leaking at all.

(2) homemade fresh-keeping bag:

Spiders are afraid of light and often make webs where there is light and wind. Spider silk can be used not only to trap prey, but also as a fresh-keeping bag. The spider wrapped the leftover food in a net for the next time.

(3) Cleanliness:

Spiders clearly divide the places where they eat, sleep and pull things. Domestic spiders generally use cages as garbage stations, urinate in them and throw food scraps.

(4) Very subtle appetite:

Spiders have a strong sense of territory and should be kept separately. They only eat one or two meals a month and can fast for two months at most. The food is mainly insects, such as crickets and Cao Meng. As long as you put a wet sponge in the cage to replenish water, you can raise it to adulthood (about seven years) without changing the cage.

Common species of pet spiders

red rose

The forests originated in South America are hairy, love to hide in mud pits and feed on insects. Red rose has strong adaptability, and the adult length is about 7.5 to 10 cm. It is the most popular pet spider at present. The price is right. Have you ever thought about keeping a furry spider as a pet? If you are busy at work, don't have much time to stay at home, and want to keep a pet, then a cool hairy spider is your best choice. Usually it's quiet, so you don't need to spend time playing. Very adaptable, only eat once or twice a week. There is no need to provide food and clean up feces every day. It will not bring noise and environmental pollution, nor will it damage your furniture.

You must have many questions: Is it poisonous? Can you bite? How to choose? How to raise it? Does it want to weave a web? What to eat? How long can you live?

Introduction:

At present, there are about 40,000 kinds of spiders in the world. According to their habits, they are usually divided into web spiders, safari spiders and cave spiders. Spiders that make webs are the most common, but they are not suitable for keeping as pets because of the problems of space and food. Cave spiders are usually kept as pets.

All spiders are poisonous! Only the toxicity is different. Usually, the toxicity of pet spiders in the market is relatively weak, and they will not take the initiative to attack people as long as they are not intentionally teased. Even if you are bitten, there is no danger to your life. Strong adaptability, no need for careful care. Spiders are the easiest pets to keep.

Spider silk is expected to be used to make high-strength materials.

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 rotator behind the spider's abdomen, which is filled with rotator glands. Protein mucus secreted by this gland can condense into extremely strong Jilin silk in the air. According to the Moscow Communist Youth League newspaper, experts from the Institute of Gene Biology of the Russian Academy of Sciences found that the hardness of this material is nine times higher than that of steel with the same thickness, and the elasticity is twice as high as that of other most elastic synthetic materials. Experts believe that after further processing, the silk raw materials in Jilin Province can be used to manufacture light body armor, protective materials for weapons and equipment, wheel tires, plastic surgery appliances, high-strength fishing nets and so on.
