The study also found that these bats can be run with four 'legs', which consists of two legs and two arms that could be developed into wings.
Bats are the only mammals that can fly. During this time, researchers thought the bat stopped running for a long time, as a result of the evolutionary process is done. If it looks like running, it was just like a fish 'jump' out of the water. Researchers from Cornell University, Daniel Riskin, said the ability of vampire bats is useful to pursue a relatively small animal. Types of animals are animals that do not sit down quickly, including when to eat. The problem, in general it is rare vampire bat chasing small animals. Instead, this vampire bats prefer cattle, especially those that spread from Mexico to Argentina and Chile, in the last few hundred years. In the laboratory, Riskin said, vampire bats are made all the animals as prey has sucked. However, in the wild, these bats prefer cattle.
Typically, these cows were targeted at night, which is bedtime for the animals. "Cattle are prey to the youngest," Riskin said, as quoted from page Live Science . The ability to run the vampire bat is not very useful to ambush the cows sleep. This is also why researchers are not concerned about the ability to run this bat. Researchers have discovered that vampire bats leg is stronger than any other bat. Leg strength is the cause of these bats are also capable of crawling and jumping. As published in the journal Nature on March 17, Riskin wrote: "The vampire bat ( Desmodus rotundus ) can walk forward, sideways, backwards, and began flying with a vertical leap. " Seeing that ability, the researchers then tested the ability to run any bat and trying to document .
The bat was then placed in a Plexiglas cage with a treadmill . In the initial speed, the bat is running at the same rate as mice. However, when the treadmill continues to run, bat it, too, picking up speed. Recorded at least these bats have the ability to run 2.7 miles per hour (or 1.2 meters per second). "bat that has little room to maneuver to move twice as fast," said Riskin. This means, vampire bats can reach speeds of 5.4 miles per hour (or 2.4 meters per second). Investigators said the bat's ability to run the motion. Therefore, "it has the aerial phase." With the capability of motion which is only used to prey on livestock, Riskin then consider bats evolved too fast. "As they are designed to pursue a racing car, but they use it to catch the school bus." Despite having only a body the size of an adult thumb, but the stretch of vampire bats can reach 8 inches. During this time, make horse vampire bats, pigs, birds as well as prey.
