Like insects, these are also invertebrate animals from the group (type) of arthropods. Outwardly, arachnids are similar to insects, but there are no wings, four pairs of legs, and the body is divided into only two sections: cephalothorax and abdomen.

Some spiders and scorpions can bite or sting very painfully. Sometimes a bite can be fatal. An interesting fact is that spiders have three pairs of glands that produce spider webs. Each pair serves for specific purposes. One is for weaving cobwebs, the other is for creating hunting snares, the third pair is for a kind of parachute when traveling downwind.

Spider representatives

• House spider
• Roaming spider
• Haymaker
• Spider - side walker (spider - crab)

House spider

The house spider is large, with rather long legs. The network weaves in the form of a hammock, turning into a funnel, where he hides.

Wandering Spider (Wandering)

A wandering spider - if you come across a bush braided by a web, in the depths of which spiders swarm, then looking closely, you can notice their mother. Wandering spiders guard their offspring growing in such openwork manger.

Haymaker

Hayman - on his legs stilts, he slowly wanders through the meadows closer to the end of summer. If you grab the haymaker by the leg, he will easily drop it, trying to escape from danger. A separate limb continues to bend, as if the scythe that is mowing - hence the name of the animal.

Spider - Bokokhod

Spider - bokokhod (spider - crab) - a bright color masks this crumb against the background of a flower in which it lies in wait for prey - pollinators. As the name implies, it moves sideways, like crabs.

Biggest spider

The largest is a tarantula spider. The distance between the legs extended to the sides is 28 cm. The mass of the female can exceed 120 g, that is, it almost matches the mass of the starling.

The smallest spider reaches 0.37 mm across, that is, three times narrower than the pin head. He lives in the forests of North America, preys on animals that are even smaller.

Biggest size difference

In spiders, females are larger than males. This difference is especially great in a spider, a spider, which is widespread in the tropics. In some species, the mass of the female is a thousand times greater than the mass of the male.

Fastest spider

Spiders patiently wait for prey, but are not able to run fast. House spiders run better than others. At short distances, they are capable of speeds up to 2 kilometers per hour.

The most dangerous spider

Deadly bites are inflicted by a stray spider living in South America. It enters homes and is believed to kill more than 100 people each year.

Guiding thread

Females of spider web spiders (for example, karakurt), moving on the ground, leave long cobwebs behind them. These threads of Ariadne lead the male to the bride’s hunting net. Now it is important that she does not mistake the groom for a mouth-watering fly. To do this, he performs a special dance on the snares, precisely encoding his tender feelings with vibrations of the web

Cowboy Tactics

Australian lasso spiders do not weave hunting nets. They patiently sit on a horizontal cobweb - a bridge, waving, like a pendulum, a thread with a sticky drop on the end. Sooner or later, a careless midge sticks to it.Then the lasso pulls up the catch and takes a leisurely bite.

Personal life of the cross

The cross is the most common spider. It can be found in the garden, park, at the edge of the forest, in the garden. It is small: the body length of the female is 1 cm, of the male - 0.5 cm. The color is from black to brown. On the abdomen there is a pattern of five white cross-stained spots on top. The web is light symmetrical - resembling a wheel, braided in one plane.

Attack on the victim

The spider hurries to the insect, which beats in the web, sensing its characteristic vibrations. He paralyzes the victim with a poisonous bite and entangles it with sticky thread released from the abdomen.

Egg cocoon

The female lays eggs in the fall, and the young hatch only in the following spring. For the winter, the female packs them in a cocoon from a yellowish web, resembling a piece of cotton candy, and hides it in a secluded place. About 600 eggs are packed in one cocoon with a diameter of about 4 cm.
