In this study, published this week in the journal Soft Matter (yes, seriously), scientists from the Georgia Institute of Technology report their detailed studies of the pooping habits of a wide variety of mammals. Using video recordings of the fecal extrusions and measuring the resulting turds, they deduce that “Despite the length of rectum ranging from 4 to 40 cm, mammals from cats to elephants defecate within a nearly constant duration of 12 ± 7 seconds (N=23). We rationalize this surprising trend by the model, which shows that feces slide along the large intestine by a layer of mucus, similar to a sled sliding through a chute. Larger animals have not only more feces but also thicker mucus layers, which facilitate their ejection.” If you are interested in pooping, be sure to check out ...
