Hallo steemian's. My biggest question today is a question that is a little silly when you read the title, but basically, my question is can give a little science to us all.
The animal kingdom's most glorious on earth everyone will answer Lions. but do you know there are other animals that are very small and even very friendly with humans, it is dragonfly.
Based on the research of Animals, Dragonfly is in the title with the most powerful predators, well, why this, let us read further research experts in the world of animals. Based on sources which I quoted from Tempo.co explains, If you thought it was a lion or a shark species, think back to your answer. Therefore, a recent study showed, most powerful predators in the animal kingdom is the dragonfly.
The African lion is listed as carnivores peaks in the food chain. However, the big cat is only able to capture 25 percent of the total prey they pursue. Great white sharks fared little better luck. Top predator in the ocean with 300 successful cutting teeth only half of the total catch prey they hunt.
Dragonflies, by contrast, looks tiny, shimmering, and is known as the insects are harmless. Even dragonflies, along with butterflies and ladybugs, grouped in the list of insects like humans.
However, behind the appearance of "friendly" it, dragonfly proved to be a very voracious predator air. Recent research conducted by a team of scientists at Rutgers University in the United States shows, dragonfly hunting a most brutal and effective in the animal kingdom.
The team of scientists noted, dragonflies capable of capturing almost all their prey with a success rate reached 95 percent. Even dragonflies often eat prey while still fly, without having to bother alighted onto the leaves or twigs.
"Dragonfly will tear its prey's body and continue to chew up shaped blobs before they swallow it," said Michael L. Mei, a professor emeritus of entomology at Rutgers, as quoted by page New York Times, Tuesday, April 2, 2013.
Appetite dragonfly practically endless. Stacey Combes, a biomechanics researcher at Harvard University who studies how to fly dragonfly, dragonfly ever witnessed in laboratory experiments to eat out 30 fruit flies in a row. "Dragonfly will continue to eat as long as there is food," he said.
A number of studies published recently have uncovered the key features of the brain, eyes, and dragonfly wings that allow the insects that hunt their prey without hesitation. One study showed, dragonfly nervous system featuring nearly the same capacity as humans, especially for selective attention. That is, the dragonfly is able to focus on a single prey being targeted, although the prey that fly in the midst of another fluttering swarm.
Other researchers have identified the existence of a sort of center contains 16 circuits of nerve cells that connect the brain to the motor center dragonfly flying in the chest. A set of the nervous system allows the dragonfly can track a moving target, calculate the trajectory to intercept the target, and subtly adjust the flight path to the target catch.
Robert M. Olberg from Union College, who reported his research in the journal Proceedings of the National Academy of Sciences, found evidence that dragonflies path intercept prey sailors used similar tricks. With the myriad eyes, the dragonfly can predict the direction fly prey, including the angle and speed, then estimate the flight of his own to capture the prey. Dragonflies know when to slow down, speed up, and fly deviate.
Dragonflies belong to different hunting technique to that done by most predators. Combes had thought dragonfly actively pursue their prey, like a lion chasing its prey. However, it is not. "It was more like an ambush predation. Dragonflies are coming from the direction which is not recognized by their prey," he said.
Dragonflies including advanced flying insects. They can hover in the air, diving in the water, fly backward and upside down, rotating 360 degrees with three times the flapping of wings and reach speeds of 30 miles per hour - incredible for a arthropods.
Dragonfly wings is also different from other types of insects. In most insects, the wing is a simple extension of the thoracic and moved as a special unit with a stretch across the thorax.
However, the dragonfly has four transparent wings that ultrafleksibel and attached to the thorax by a separate muscle. Each wing can maneuver independently, allowing dragonflies perform various flight maneuvers. "A dragonfly can lose all their wings and they can catch prey," said Combes.
As a complement to this tu8lisan, I also show you some pictures that I captured today as dragonflies very small size is hunting his opponent before they ingest as food.
