According tomedia reports, canniable spiders have a very obvious feature of all known spider species — their eyes are the largest, and they are 2,000 times more able to see things in the dark than humans. Now it seems that amazing vision is not the only advantage these spiders have. New research suggests that the spider can hear sounds even though it has no ears. Spiders can hear low-frequency and high-frequency sounds through the leg sensor.
The researchers say they can detect sounds at least 6.5 feet away from the source. In addition, they are sensitive to frequencies up to 10 kHz.
In their study, the scientists used both laboratory testing and field observation. They showed that the flapping of the wings of moths, mosquitoes and flies in the same low-frequency range stimulated the spider to attack back. Back-attack is one of the iconic spider hunts. This led the researchers to determine that spiders use auditory cues to detect and capture flying prey.
Jay Strafstrom, co-author of the study, points out that spiders are a “gold mine” for information. Observations made in the study show that not only do spiders have incredible visual abilities, they also hear sound well. Canniverted spiders are tropical animals found all over the world, including in the United States, especially Florida.
Spiders come out day and night, hiding in the leaves of plants during the day. During the day, the creature tends to pretend to be dead and come out at night to hunt its prey. Spiders attack forward to catch their prey below them, and back to catch their flying prey. The study found that the way you hunt depends on different senses.
