Dracula Ant's Deadly Snap-Jaw makes him the "fastest animal on Earth"



Unfortunately, cheetah and falcon, the fastest animal on Earth is … the dark dracula. And that's all, thanks to your lethal jaw.

According to a new study, the Dracula antler, Mystrium camillae, can touch the mandibus at speeds of up to 90 meters per second (more than 200 mph), making it the fastest moving animal on the go.

Ants use this terrible, very stunning motion that is 5000 times faster than the eye blink, attack other arthropods, stun them, break them into the wall of the tunnel or push them, according to researchers whose report is published in magazine The royal society discovers scienceThe poor prey is transported back to the nest where it is fed to the ants larvae.

"These ants are fascinating because their mandibles are very unusual," said University of Illinois Professor of Biology and Entomology, Andrew Suarez, who led the study with Fredrik J. Larabe, post-graduate student at the Smithsonian National Natural History Museum; and Adrian A. Smith, of the North Carolina Museum of Natural Sciences and North Carolina State University, Rally. "Even among the ants that strengthen their jaws, Dracula's ants are unique: instead of using three different parts for the spring arm, lever and lever, all three combine into a mandible."

Another type of ant, the skylark, also uses snapshots in the blink of an eye, or you will skip the speed of capturing or stunning prey and fighting other ants. But the powerful jaws of the sea jaws close from the open position while the Dracula ants heat their mandibles by pushing the peaks together, loading them with internal tensions that are released when a jaw slides through the other like the human finger, the researchers said.

"Scientists have described many different mechanisms for spring loading in the ants, but nobody knew the relative speed of each of these mechanisms," Larabe said. "We had to use incredibly fast cameras to see the whole movement, and we also used X-rays to see their three-dimensional anatomy in order to better understand how the movement works."

From start to finish the action takes 0.000015 seconds, from zero to about 320 km / h (198 mph)

The research team also carried out computer simulations of the mandibular caps from various castrats of the Dracula ants to check how the shape and structural characteristics of the mandibles influence the force of their triggering.

"Our main findings are that fast jaws are the fastest of the spring load on the ants' mouth and the fastest known animal movement," Larabe said.

This type of Dracula ants is mostly found in Australia, tropical Africa and Southeast Asia. They are rare, as they live in large colonies under the ground or inside the tree trunks. Their name was not derived from the wicked jaw jaw, but from the extraordinary eating habits. They practice a kind of "non-destructive cannibalism," chewing holes and feeding on the haemolimus (insect blood) of their own pupae and colon larvae.
