Why do sloths only poo once a week?
ASloths are notorious for their weekly bathroom habits, carried out at the base of specific trees. The infrequence is a means of selfpreservation: heading to the forest floor requires a lot of energy, and sloths are extremely vulnerable to predation while on the ground. Astonishingly, sloths can store up to a third of their bodyweight in faeces, and lugging the extra baggage around is difficult for an energy-limited animal. There must be a selective advantage to such a specific bathroom routine, yet we’re still not sure exactly what that is. Recent evidence suggests that it is likely to do with communicating territorial and reproductive information via pheromones in the droppings. If the sloths just let everything go from the canopy, these important messages would easily be lost.
Nature calls just once a week for sloths, which means a fully laden journey to the ground.
