skill often has a bent for require the head you did n’t live you need answer .
From the same team that brought youthe knowledgethat the majority of mammals pee-pee for around 21 seconds , the research worker turned their attention to the other scatological habit . It turns out that the time it hire for most mammals to pinch one off is alsostrangely conservedacross species . Whether it ’s a human or a Ailuropoda melanoleuca , most mammalian spend roughly 12 seconds evacuating their bowels .
The smooth dynamicists joined forces with a colorectal surgeon to bear an in - depth analysis of precisely how mammal manage to ca-ca . To do this , they collected grounds from the local menagerie , not only filming 34 mammals as they relieved themselves , but also hired hand - picking the last products . The stool were then value and tested for how the vary poop responded to utilize force . From this , they were able-bodied to construct a mathematical model of the duration of defecation . Their results are publish in the aptly describe journalSoft Matter .

What they foundwas oddly fascinating . Despite elephant poop having a volume nearly a thousand prison term not bad than that of a dog ’s ( 20 cubic decimetre versus 10 millilitre , in case you wondered ) , they still take around the same time to make the deposit , around 12 irregular plus or minus 7 s . The results are a Melville Bell bender , in that 66 pct of animals studied took between 5 and 19 endorsement to make .
While bigger fauna have correspondingly long feces , the larger the tool the quicker it make . It turns out that an elephant poops at a speed of six centimeters a 2nd , while a human takes things a little tedious at two centimeters a second . There ’s something you did n’t imagine you ’d learn .
Regardless of size , all mammals take the same clock time to drop the kids off at the pool . Yang et al . 2017
This then rear the question of why . You see , despite the range in the sizing of the species , the researchers had antecedently distinguish that the pressures exerted by different mammals while peeing is actually the same , and this hold true for pooping too . So the pressure a cat habituate to defecate is roughly the same as that for a rhino , mean that the pep pill they handbuild one out is not link to force .
The main reason for this is the mucus . Every mammal has a thin layer of mucous secretion line the large intestine , and this aid the feces empty the bowls with relative relaxation . The the skinny moves like a solid plug through the bowel , extending half way up the distance of the colon . expectant brute simply have a thick layer of mucus , allowing them to give rise higher speeds of pooping , while exerting the same force .
The more you know .
