Pauk-krugopryad and other representatives of the family of the same name have interesting feature in the external building. The fact is that the paunch at them is much more, than at other spiders, and their external chitinous skeleton is rather soft. But, despite vulnerable appearance, krugopryada are ruthless hunters with poisonous helitser.
As the spider-krugopryad looks
The trunk of a spider-krugopryada (and any other species of arachnoid animals) is formed by merge of two visually distinguishable departments. The first department is golovogrud (or pro-som). On it at a krugopryad is located the whole six pairs of extremities! Two front couples will be transformed to pedipalpa and helitser and are located in his mouth. Other four couples are hodilny legs.The second department is a back part of a trunk, it is called a paunch (or opistosomy). The paunch of a krugopryad is capable to vary rather strongly in the sizes thanks to high elasticity of an external skeleton. Besides, after a good meal or before the female of a krugopryad begins to lay eggs, it can vary (paunch) rather strongly in the sizes, increasing almost twice in relation to the usual size.Pauk-krugopryad has a black paunch with yellow to spots. His hodilny legs, beginning from the paunch basis, are painted in yellow color which then passes into black. By the way, at females of a krugopryad the hodilny legs are much longer, than at males, and helitser are filled with lethal poison! Such coloring says that these spiders are rather poisonous creations.
Where lives also what the spider-krugopryad eats?
In general places of favourite dwelling of krugopryad depend on habitats of the flying insects. They form the basis of a nutritious diet of krugopryad. Best of all for this purpose bushes, the woods and the gardens approach: abundance of various flowers as if the magnet, attracts to them insects – food of krugopryad.
Pauki-krugopryady during the marriage period
The ability of spiders to spin the web admires scientific and narrow-minded minds for a long time. The ability to spin lovchy networks is one of the most surprising manifestations of activity of representatives of a class of arachnoid animals. Krugopryadam is ability it is necessary not only for production catching, but also for pairing. Having caught sight of a female, the spider-krugopryad hurries to approach her. However he does it in a special way: he touches the spider lines in a certain order. It allows a female to understand correctly that for "groom" to her welcomed and also to make sure of sincerity of his intentions. Before pairing the female of a spider-krugopryada processes a web a specific pheromone. It needs to be done in order that the male made sure of arrangement of a female to it in advance. Then the male of a krugopryad slightly touches front legs of a female and begins to spin quickly around her an invisible web. So it shows the abilities. After that there comes the most dangerous moment in pairing of spiders-krugopryadov: the male begins to enter semen through special pedipalpa. After the coition was made, the male needs to abandon a female quicker. Especially slow "grooms" turn into a nourishing lunch.
