A very special spider without poison kills prey with a smart trick: what weapon does he use

However, biologists suspected that representatives of this species probably use another chemical attack method to kill the prey. Now scientists have finally found out what strategy this species uses, writes Science Alert. In focus. Technology has appeared its Telegram channel.

In a new study, the ecologist at the University of Lausanne Syozin Pen and colleagues found that spider-circus spider toxins from the middle intestine on their silk wrapped in production to curb it. It is interesting that spiders in the intestine are different from those contained in the fangs of poisonous spiders. And yet, they are similar to immobilization of prey.

According to another co -author of the study, Ecologist Julia Zanko from Lozan University, spiders' poison samples were very insecticidal, killing an average of 50 percent of fruit flies within an hour after infection. Researchers have also found that these toxic proteins were similar to proteins in digestive fluids of other spiders, such as Parasteatoda Tepidariorum, despite the fact that this species also has poisonous glands.

The results of the study also show that spider toxins are not limited to exclusively specialized glands that secrete poison. The team found that they also play a role in the digestive system. According to the researchers, this confirms the evolutionary relationship between the two systems, assuming that toxins could initially perform digestive functions before used to use the poison. Researchers have also confirmed that unlike their poisonous brothers, U.

Plumipes has no ducts in fangs for injection. The team suspects that the widow spiders probably lost their poison over time and then compensated for this loss, having mastered the use of their digestive toxins. Although spiders are often afraid of their toxicity, they play an important role in our ecosystems, holding back the number of insects and providing food with many birds, reptiles and other animals, even humans, some of which have a rather spectacular look.

Their poisons have also shown perspective for potential medical use, so you may also need to study the properties of their intestinal toxins. Spiders have attracted the attention of scientists for years and sometimes scientists have taken strange steps to study the behavior of spiders. For example, NASA experts repeated the experiment of a Swiss scientist, in which they gave spider caffeine and forbidden drugs, and then watched how spiders weave their web.
