Cause lazy almost died every time defecation

Despite the risk of losing their lives, lazy species always climb down the tree to dispose of each time a week.

Due to lazy movement, they usually take up to a month to digest some food. Their intestinal system works really slowly, causing them to become seriously constipated and only once a week. Not only that, lazy to climb to the ground to conduct this activity and easily become the target of predators.

According to The Washington Post, lazy can lose 1/3 of body weight after each excretion and this activity is extremely difficult."You can see that their stomachs shrink when defecating," said Rebecca Cliffe, a lazy biologist at Swansea University, UK.

Fecal discharge is the only reason to be lazy to leave the tree and stand upright . According to Cliffe, they dig a small hole to dispose of the manure in it, fill it up after finishing work and climb back to the tree.

Researchers do not know the reason why bowel movement is lazy and takes time and what motivates them to risk their lives leaving plants for excreta. A hypothesis led by the University of Wisconsin, USA research team in 2014 is lazy to waste in such a strange way to maintain a balance between them and moths.

In symbiotic relationships, moths living on lazy bodies help a type of algae in the feather to reproduce. This algae is important for lazy survival because it helps the coat to be green, allowing lazy to disguise predators and providing nutrients to lazy absorption through the skin. Therefore, it is possible to lazy to climb down to the ground to provide fertility for moths to complete their life cycle.

Cliffe thinks this hypothesis is unconvincing when considering the danger of being lazy to face the ground. More than half are lazy when not in the tree. In addition, captive sloths do not need moths or algae to survive, but they still do the same behavior. Cliffe hypothesizes about mating.

"This is a life-and-death act. I think this behavior is related to reproduction, because that is the factor behind most of the confusing behavior in animals, " Cliffe said.

Cliffe's hypothesis is to help mark the tree in front of other sloths, letting them know there's a fertile female living on the tree. Cliffe stressed that more research is needed before making a final conclusion.
