Scientific American has now asked and answered the questions you were either to afraid to ask or never wanted to know. How fast is the bowel movement of an elephant and how does that compare, to say, a dog? Which species produce “floaters” and which “sinkers”?
A true gem from the article, “The Physicics of Poop”:
Together, this meant that defecation duration is constant across many animal species – around 12 seconds (plus or minus 7 seconds) – even though the volume varies greatly. Assuming a bell curve distribution, 66 percent of animals take between 5 and 19 seconds to defecate. It’s a surprisingly small range, given that elephant feces have a volume of 20 liters, nearly a thousand times more than a dog’s, at 10 milliliters.
Now that’s good math.
