The habits of spiders, the habits of life of spiders

The easiest way to lure a spider is to create keywords. Many ** have not been crawled by spiders before, if you want to attract spiders over, you must first set a keyword, and pay attention to the uniqueness of the keyword. Find some words that have low relativity of search results, put them on the page you need spiders to care for, and explain them.

There are many webmasters who will complain that ** publishes originals every day and updates data every day, but they just don't include ** content and don't increase the weight of **. Actually, it's not that you are not included, and the spider is also there every day, but it will be a new ** for a period of time, and when you pass the investigation, you will have a large number of web pages to be included, and then your ** weight will increase. Therefore, you must hold on during the period of time you are being examined.

Go to high-authority ** or forums and post articles that revolve around your own keywords. You can bold or color these keywords, and then link these keywords to your homepage, and add the homepage address to the content once or twice. Here, a few **::

A5, China Webmaster Network, Laggards and China Professional Webmaster Network. There are more original content of these **, and the update rate or weight when you are bored is better.

The keywords are done, the information is released, and now all that needs to be done is to trigger the detection database. So how do you trigger the keywords created by the search? There are many ways to do this, such as going to popular forums and posting information that people will be interested in at a glance.

The spider is an automated program of a search engine. Its function is to access web pages on the Internet, establish an index database, so that users can search for your web pages, content and other content in the search engine. Pretty good.

1. Feeding habits: Spiders mostly feed on insects, other spiders, and myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them.

Crab spiders wait for their prey on flowers that are similar to their body color. Spiders burrowing in the earth build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects that pass through the hole. funnel spiders weave funnel webs, and insects fall into the nets to cause vibration; The spider itself resides in a filament tube with a narrow end that leads into a plant or a crevice in a rock.

2. Lifestyle: The lifestyle of spiders can be divided into two categories. That is, the nomadic type and the sedentary type.

Safari type spiders, spiders that hunt everywhere, hunt, have no fixed residence, do not build webs, do not burrow, and do not build nests. There are scaly arachnidae, ursoaradae and most tarantulas. Sedentary:

Some build nets, some dig holes, and some build nests as fixed dwellings. Such as wall money, stone-like spiders, etc. Spiders seem to be polite, and those who live independently keep a certain distance from each other and do not invade each other.

Spiders can be found on water, land, and air. Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. They all rely on spinning silk and weaving nets to catch food.

1. Ghost spider.

Ghost spiders are invertebrates and a class of small bulk spiders. Representative species include long-heeled ghost spiders. They are accustomed to living in indoor corners, under washbasins, in the cracks of cabinets, and without sticky simple webs, they are indoor spiders.

There is a habit of weaving nets, but the nets are irregular, and they like to live in dark corners of the house. Feeds on insects.

2. Tarantula. Activities on the ground, ridges, ditches, farmland, and plants. When resting, they hide under stones or in crevices in the soil, and some species burrow. They usually come out to forage during the day and at night in warmer areas. It has a large amount of predation and is an important natural enemy of pests in farmland.

3. Giant spiders.

Giant spiders live alone in their own crypts. It hides in crooked burrows covered with foliage during the day and only goes out at dusk and night, preying mainly on rodents such as mountain rats and small mammals such as marsupials, and sometimes snakes.

4. Water spiders.

Living in the world of water. Water spiders feed on small fish, tadpoles, insect larvae, and small animals like leeches in the water.

5, Poison Widow.

Black widow spiders usually live in temperate or tropical regions. They generally feed on a variety of insects, although occasionally they also prey on lice, horses, mosquitoes, and other spiders.

When the prey is entangled in the net, the black widow spider quickly strikes out of its perch, wraps its prey securely with a tough web, and then pierces the prey and injects the toxin. The toxin takes effect in about 10 minutes, and the prey is always tightly held by the spider. When the prey's activity stops, the spider injects digestive enzymes into the wound.

The black widow spider then brings the prey back to its habitat for use.

Tiny spiders have dexterous and complex body structures that make them worthy of carnivores.

The title. The body of the spider is simply divided into two parts, cephalothorax and abdomen, with a tiny waist connection in the middle. The cephalothorax includes the forelimb portion, the head, and the thorax. The spinning organ on the abdomen is the organ that spins silk in spiders. Spiders have a total of eight segmented legs, and they are extremely agile in crawling.

Spider eyes are in front of the head, most spiders have eight eyes of various sizes, some spiders have six eyes, and a few spiders have no eyes, or have two, four or 12 eyes, scientists don't know why spiders have so many colorful eyes. Although the spider has many eyes, its vision is very average, and what it sees is always blurry, so it can be said that the spider is a poor short-sighted eye.

Spiders have tentacles that are used to grasp prey, and chelicerae that can move up and down flexibly (e.g., birdcatchers).

or panning (most spiders). Panning allows the jaws to be angled wider, so spiders can also hold prey larger than their bodies.

Spiders secrete mucus through protrusions at the tips of silk sacs, which can congagulate into very thin filaments when exposed to air. Spiders have six glands in their abdomen; Called a spinner. Various glands produce different types of spider silk.

At the tip of the gland is a spinneret with thousands of small holes, and the liquid that spews out condenses into viscous and tense spider silk when it hits air. It is said that a thousand spider threads are one-tenth thinner than a human hair. Spider silk is made up of a silk prion protein.

In terms of a specific diameter, the tensile strength of spider silk is greater than that of steel.
