Elephant The trunk sucks very much — that’s good. The strong suction allows elephants to cleverly grab small, delicate foods and even fragile tortilla chips that can be crushed or crushed by the grip of a muscular trunk. I can do it.
High-speed video recently revealed that the success of this inhalation was due to the strength of the elephant’s inhalation. Researchers have calculated that elephants can smoke at speeds of over 336 mph (540 km / h). This is more than 30 times the speed of air exhaled when a human sneezes (about 10 miles (16 km / h)) and is faster than JR, according to the Shinkansen (199 mph or 320 km / h). Nippon Railway).
You can put more in their trunk than you think. Elephants can increase the diameter of their nose by widening their nostrils. According to a new study, this reduces the thickness of the inner wall of the trunk and increases the internal space by about 64%.
The elephant’s nose can perform unexpectedly delicate tasks, even though it weighs a whopping 220 pounds (100 kilograms). Draw a “self-portrait” Grab the cereal flakes with the tip of the trunk, Previously reported live science..
Previous studies have shown that elephants can form. Blow air from the trunk The author of the new study wondered if an elephant could use his nose like a vacuum cleaner to smoke a delicious treat, much like he would suck water or dust into his body. Andrew Schultz is a PhD candidate for mechanical engineering at the Georgia Institute of Technology in Atlanta.
“Big vacuum cleaner sound”
Using three video cameras, scientists recorded a 34-year-old female African elephant experiment at the Zoo Atlanta and showed her a tortilla chip and a rutabaga cube.Then they recorded and collected the video Ultrasound Measures of the elephant’s nose when the elephant sips water from the aquarium. The study’s authors then used observational data and data from frozen trunk trunk measurements borrowed from the Zoo Atlanta Zoo and the Smithsonian National Museum of Natural History in Washington, DC to determine trunk capacity. I calculated the pressure.
The elephant inhaled and lifted multiple small objects and a single item. The study authors report that when there were more than 10 small pieces of rutabaga on the table, the elephants used suction to pick them up and make a “loud vacuum cleaner”. More delicate. For the tip, the elephant used suction in two ways. Suck the tip from a distance, or first press your nose directly against the tip, then suck and lift it off the table. According to scientists, the task of lifting these chips was very gentle.
“Elephants were usually able to pick it up without breaking it, even after repeated attempts,” the researchers write.
Experiments in the aquarium further demonstrated the powerful inhalation rate of elephants. Pre-soaked chia seeds help show the flow of liquid. The elephant surfaced nearly a gallon (4 liters) of liquid in 1.5 seconds, but at first it looked like more liquid than the trunk could hold reasonably well, Schultz said.
“At first it didn’t make sense. The elephant’s nasal passages were relatively small and inhaled more water than necessary,” he said. Said in a statement“We didn’t do that until we looked at the ultrasound images and understood how the nostrils were widening. The air opened the walls and the animals were much more than we initially estimated. It can store a lot of water. “
Elephants are special and can suck food. Respiratory system The authors of the study write that it responds to abnormally high lung pressure and produces an air velocity that is unmatched in terrestrial animals. For example, the human lungs barely suck enough to lift a “small piece of paper.” Those who can generate force and attempt to aspirate and lift the tortilla tip should place their nose within 0.02 inches (0.4 mm) of the subject. According to research.
Even then, humans probably couldn’t smoke enough to do the job. “If liquid leaks between the tip and the nose, you can’t lift it,” scientists write.
The findings were published online on June 2nd. Journal of the Royal Society Interface..
