Mechanism to catch spooky prey of spiders

While many people think that they know enough about the horrors that spiders bring, a new study has announced their ability to capture prey and should learn.

The multi-labeled species has the ability to twist their spider webs, creating elastic pressure before loosening the web, sending them towards the prey with tremendous speed. The new finding has put the spider species with the scientific name Hyptiotes cavatus next to humans to know how to use the tool to maximize muscle energy, just as in the case of humans designing and using crossbows, to make Attack the target from afar.

Expert Sarah Han, who is a doctoral student at Akron University (Ohio, USA), said this is an interesting hunting mechanism that humans have not yet grasped in spiders. Ms. Han and her colleagues observed the spider species in laboratory conditions, recording their activity during hunting, in this case flies.

'The spider uses muscles to twist the spider web, like how you pull the crossbow string or it - keep it in place until the prey is in sight,' Han said. That means that the spider can persist in keeping the pressure and not vibrate for hours until it reaches its goal.

When the spider dropped the wire, the whole network and spider all rushed forward with lightning speed. Before the prey is able to cope, the network has rushed to surround it, starting the remote fishing process. According to a report published in the Proceedings of the National Academy of Sciences (PNAS), the calculations calculated that these spiders shot themselves forward with acceleration of up to 772.85m / s ² , which means folding About 26 times the maximum acceleration of the shuttle spacecraft operated by the US Aerospace Agency (NASA). Animals also maintain an unchanging posture from winding, allowing them to effectively attack the prey from afar, reducing the risk of suffering damage to the body. This is also what people can learn from multi-label species in the field of developing amplified weapons of attack power.

According to Han, there may still be spiders that know how to accumulate energy in spider silk to catch prey, opening up another area for human research. Not stopping there, the research team has not yet analyzed the 'capture mechanism' of the Hyptiotes cavatus spider, promising practical applications if humans can successfully research. 'It is worth studying how a spider with its small body maintains its enormous energy compared to its size , ' Han said. 'Perhaps we will find something new that can be applied in the human world , ' she concluded.
