Scientists have been interested in this problem since 1900. They conducted many experiments with spiders, wrote scientific papers about these insects, but until now they have not come to a consensus.
At first, scientists believed that spider legs secrete a special fluid that prevents them from sticking to the web, but they could not find it. Then it was believed that the heterogeneity of the web, which consists not only of sticky, but also of non-sticky threads, helps spiders move along it. But then they proved that spiders can move freely along sticky threads. Other scientists believed that it was all about the special structure of the insect's legs.
Scientists from Puerto Rican helped to answer this question. During the research they used a microscope together with modern recording technology. Thanks to this, a unique record was obtained, from which it is clear that spiders do not stick to the cobweb with the help of several aids.
They have hairs on their paws that reduce the area of contact with the adhesive surface, and the movement of the paws itself is also very important. But the most important thing in the resulting video is that it captures the process of fluid release, which reduces the adhesion of the cobweb.
