Impressed? Does it make you want you had a trunk?
In “Elephant Trunks: Is There Anything They Can’t Do?” Richard Sima writes a few new research concerning the energy and wonders of an elephant’s most defining appendage:
An elephant’s trunk is a marvel of biology. Devoid of any joints or bone, the trunk is an appendage manufactured from pure muscle that’s able to each uprooting timber and gingerly plucking particular person leaves and likewise boasts a way of scent extra highly effective than a bomb-sniffing canine’s.
Elephants use their trunks in quite a lot of methods. They use it to drink, retailer and spray water, they usually additionally blow air by means of it to speak — their 110-decibel bellows could be heard for miles.
“It’s like a muscular multitool,” mentioned Andrew Schulz, a mechanical engineering doctoral pupil on the Georgia Institute of Technology.
In a research revealed Wednesday in The Journal of the Royal Society Interface, Mr. Schulz and his colleagues reported on how elephants can use their trunks for one more perform: making use of suction to seize meals, a habits beforehand considered unique to fishes.
Despite the ubiquity of elephants in youngsters’s books and nature documentaries, there are quite a few gaps in scientific information concerning the biomechanics of their trunks that the brand new research helps fill. For instance, the newest detailed account of elephant trunk anatomy is a hand-drawn monograph that was revealed in 1908, Mr. Schulz mentioned.
Contrary to common perception, the trunk doesn’t act like a straw.
“What they do is actually drink water into their trunk and they store it,” Mr. Schulz mentioned. “So the elephant trunk is actually like a trunk.”
Students, learn the complete article, then inform us:
