How spiders hunt, how spiders hunt and eat food

Spiders in reality with webs.

In Warcraft, spiders spit stones on the ground and use webs against the air.

Interstellar spiders can only attack if they burrow underneath.

The most important characteristic of a web-forming spider is its web-forming behavior. Spiders secrete mucus through protrusions at the tips of silk sacs, which can congagulate into very thin filaments when exposed to air. Webs made of silk are highly sticky and are the main means of predation for spiders.

For insects that stick to the net, spiders will first inject a special liquid jujube digestive enzyme into the prey. This digestive enzyme causes insects to stun, convuls, and die, and liquefies their bodies, which feed spiders by sucking. Spiders are oviparous, and most male spiders are devoured by female spiders after mating with female spiders, becoming food for female spiders.

The way spiders hunt.

1. The spider is a genius architect, and when it builds its web, each spider silk maintains a certain distance, as accurately as measuring it with a ruler.

2. The round web spider feeds on moths, flies, butterflies, grasshoppers and beetles stuck to the spider's web; Like to eat all small prey, the nest must have a fulcrum capable of forming webs, the round web spider relies on its own vertical and open web to hunt, it sprays its own spider silk to wrap the prey, and then gently bites with its fangs, waiting for the prey to die of weakness.

3. When the spider eats, it does not chew the food with its teeth, but uses the digestive juices in the mouth to dissolve the food into gravy before sucking.

Spider species. There are many species of spiders, and there are more than 40,000 species of spiders in nature. These spiders can be broadly divided into three types: hunting spiders, web-building spiders and cave spiders.

The first group will forage for food, and the second group will set up nets and wait for the rabbits. And most of the people who keep them as pets are in the third category: cave spiders.

Cave spiders like to hide in sand or burrows, and build webs at the mouth of the holes, which are not sticky and are purely used to sense the size of their prey and prey on them. <>

How to prey:

Spider predation is relying on the web to catch the prey, the spider weaves the web and returns to the center of the web to wait for the prey, the spider silk has a strong adhesion, the prey struggles violently after hitting, the spider in the center can sense, the spider will inject toxic digestive enzymes after catching the prey, first poison the prey Xian Changyou, and then drag the prey to the center of the web.

When the prey is unable to struggle, the spider will use its abdomen to spit out spider silk and wrap the prey firmly around its whole body until the prey dies, so that the prey cannot escape the spider's palm.

Spider Lifestyle:

The lifestyle of spiders can be divided into two categories, namely nomadic and sedentary, nomadic people, hunting everywhere, predators, no fixed residence, no webs, no burrowing, no nesting spiders, scaly arachnidae, bear spiders and most tarantulas, etc., sedentary type some webs, some burrowing, some nesting, as a fixed residence, such as wall money, stone spiders, etc.

Spiders seem to be polite, all those who live independently, individuals maintain a certain distance between each other, do not invade each other, compared with ordinary insects, spiders are long-lived brothers, most spiders complete a life history, generally 8 months to 2 years, male spiders are short-lived, and die soon after mating.

Others such as water spiders and cunning spiders can live for 18 months, burrowing tarantulas can live for 2 years, cancer spiders can live for more than 2 years, and bird-catching spiders have a lifespan of up to 20 to 30 years.

Cave spider, in the web during the day, at night at the entrance of the hole, waiting for the opportunity to hunt or go out to forage, the male spider digs a shallow pit under the clods, the burrowing tarantula digs a vertical deep hole in the ground, the dancing spider also adds a live cover at the entrance of the hole, this kind of live cover is composed of a plurality of silk layers, the hole of the spider is up to 1 meter deep, the spider body is small, the poison is strong, once the bite of the cave rabbit, four minutes will die.
