Have you ever heard the sound of the bell tail nearby? According to a new study released on Thursday (August 19) in Current Biology magazine, reptiles with venom will change their continuler frequency when people come near them .0: 00 / 2: 49 South regions A study shows that their frequency changes the frequency of the frequency depends on the distance of the threats. (Photo: CNN) Solid bells often hunting small animals like rodents and will vibrate their tails when they feel threatened, Whit Gibbons, professor of Ecology in Georgia University in Athens, The person who does not participate in the study, said. In visiting a animal base, the main author of the Boris Chagnaud study found that the bell's tail snakes always changed their cry into a higher frequency when he came Near and lower it when he walked away.Chagnaud, Professor of Biology at Graz University in Austria, said it was similar to backing the car
.Chagnaud noted that "sound signal warning you a way Body behind you "Emit a beep faster when you are near a more object. According to the study, the snakes that increased the frequency from about 40 Hertz to 60-100 Hertz when people approached. (Frequency of sound is measured with Hertz
) After conducting additional testing to confirm this model, Chagnaud said he worked with other researchers to design a virtual reality environment where The virtual snake also reacts the same way. Scientists have put objects into the virtual environment with a pair of virtual reality glasses and a loudspeaker room. When people pass through the meadow area, they were asked to stop when they believed that the snake was one meter away (just over 3 feet) .Chagnnaud said: "The objects are underestimated the distance to the virtual snake Whenever it jumps on a higher frequency range. This means that the frequency emitted higher makes people believe that the snake is closer than it, that can be a survival technique, he explains .Chagnaud said: "It is likely that a large mammal species can stop and don't step on good camouflage snakes." These findings are meaningful because the bell's tail solid tries to avoid conflicts when they can, Gibbons say. He said: "Like other snakes, the tail of the bell, which has a lot of species in North America, Quan The mind comes not to be discovered rather than confronting any animal other than their prey. Although the bell's tail solid can protect itself with venom but the snakes try to avoid using it when It can be added, these reptiles also want to avoid breaking fangs or fighting with larger animals such as meadow wolves and honeysthags.gibbons said, continental spaces can also be used To lure the prey
Besides, he believes that future studies will focus on how the bell's tail solid uses their rattles to attract prey, "can pass the ability to imitate hearing Chagnaud said one of his doctoral students has recommended research to see what parts of the human brain Reacts with the leaps of the frequency of the creek, and then explains the wrong distance of the snake, to see if the scientists can better understand why the snake can trick people or not.
