The lifestyle of spiders can be divided into two main 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.

The body of the spider is 1 90 mm long, and the body is divided into two parts: cephalothorax (anterior) and abdominal (posterior), and the cephalothorax is covered with dorsal armor and chest plate. There are two pairs of appendages in the cephalothorax, the first pair is chelicera, with chelicera, and the tip of the chelicera has a toxic gland opening; The chelicerae of the rectal palatal suborder move anteriorly and backward, and the lateral and opposite movements of the palatal suborder; The second pair is whiskered, which are in the shape of a female and an immature male spider in the shape of a foot, which is used to hold food and act as sensory organs; However, in males, adult spiders are enlarged at the end of their whiskers.

Spiders feed on insects, other spiders, 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.

8 foreheads, remind you, spiders are not insects, insects are head, chest, abdomen three parts, only 6 legs downstairs people talk nonsense, misleading people's children.

Spiders belong to the arachnids of arthropods, the animals of the arachnid class have 8 legs, and there are many species of them, there are about 35,000 species in the world, and they are.

Some have nets, some have not; Common web-forming spiders include round spiders, bulbous spiders, wall money, network brides, etc., and spiders that do not web-forming include flies, tigers, and wolves.

Spiders, jumping spiders, crab spiders, etc. Web-forming spiders have no segments in the cephalothorax and abdomen, and have 8 single eyes at the front of the cephalothorax, which can sense the intensity of light.

Weak; The ventral surface of the cephalothorax has 6 pairs of segmented tarsal limbs, the first pair is called chelicera, and the tip is a venomous gland foramen, which is used for predation or self-defense; At the posterior end of the abdomen there are 3 pairs.

Protrusions, called spinders, are used by spiders to form webs. Web-forming spiders use their webs to catch small insects, while non-web-forming spiders swim around to hunt.

Spiders are beneficial animals for humans.

It has 4 pairs of feet, divided into base joints, turning joints, leg joints, knee joints, shin joints, back kneeling joints, heel joints and taektail joints (upper claws). The feet are covered with bristles and have several sensory organs, such as elongated bristles (which sense air currents and vibrations).

After self-cutting, it can be regenerated the next time it molts.

Spider habits:Because spiders are highly sensitive to changes in environmental factors including habitat structure, habitat type, wind, humidity and temperature, they can be used as indicator groups to monitor habitat and biodiversity changes, and their species composition and population changes have become important indicators for environmental monitoring, which can well reflect the process of environmental change and its impact on biodiversity.

Spiders have 8 legs, each leg can be divided into 6 segments.

Spiders are a small animal that people often see in their daily lives, the largest ones can be 10 centimeters long, and the small ones are only 1 millimeter long. They are very diverse and widely distributed. It is already known that there are more than 22,000 species of spiders in the world, and there are at least 3,000 species in China.

We can find clues of them in forests, fields, grasslands, water's edges, under rocks, and indoors, and even in the underground and water.
