With the spiders is associated with many superstitions, many believe they are dangerous, and people who are afraid even ordinary individuals called arachnophobia. Scientists say all the really poisonous spiders. But not many pose danger to humans because the venom of most spiders is not toxic to us. However occasionally in our region, for example due to weather anomalies, can appear arthropods, which are able to cause harm to humans. Therefore it is not recommended to disturb the spiders, ripping their web or try to catch.
Experts Mospeada managed to capture on natural territories of representatives of some species living in Moscow.
This is the largest family of spiders, which includes 5,800 species. They have excellent eyesight, which they use for hunting. These spiders have eight eyes arranged in three rows. An overview of almost 360 degrees provided by the four large eyes on the front of the head, two small in the middle part and the two middle corners back of the head. These spiders can change the size of their limbs and jump long distances far exceeding their body length, so called horses.
these spiders, on the contrary, the eyes quite small, since the Orb-web spiders use the other senses. Orb-web spiders — skillful builders of networks. The web consists of triangles connected to each other and converging one of the angles in a common centre, forming a circle. Inside each triangle, they spun a web, radiating from the center to the edges. Moreover, the web has a very neat appearance, the cells of one row do not differ from each other in size and multiplies by the web. Interestingly, the cell sizes vary by Builder depending on what prey it counts: in small or large.
They are called spider crab because of its ability to move sideways. Bokachoda do not weave webs. They use the sticky substance to create pouches in which the females lay eggs, and in order to climb down the plants. Fall bags family of spiders can use as a glider: with the wind they can fly them a few miles. To stay in any place, they release the web and cling to the nearest plant. Hunted by large and powerful front legs, clasping their victim.
These spiders are experts at camouflage, their color is usually dark brown, gray or black, so almost all kinds of blend in with the environment. The fact is that wolves, spiders are solitary, living in burrows, wrapped in a thick layer of cobwebs, leaving them in the night for hunting, as traps do not weave webs. But it is very important to the ecosystem animals, because they regulate the number of��of comah.
As the Orb-web spiders, the sand built round net for catching prey, but they are distinguished by the presence of holes in the center where the spider usually sits most of the time during the day. In Moscow and in Central Russia distributed genus “metallina”. They can often be found in parks and gardens.
the Well-known arthropods, which are mistakenly attributed to the class of arachnids, is harvestmen. These creatures with very long legs and small body often strive to get into our house. Their scientists have identified a separate detachment harvestmen, which today has over 6,600 species. Unlike spiders, harvestmen are not poisonous and do not have spider glands. As a protective mechanism they use autonomy — a drop of the limb. When you attack their legs painlessly separated from the body, and senokot flees.
