In fact, you might wonder how such an animal survives in the wild at all. Share this post:. Despite this apparent deficiency, sloths have a highly unusual muscle arrangement which gives them surprising strength with a very high resistance to fatigue. Maintaining a stable core temperature is energetically very expensive, and sloths appear to have almost completely sacrificed this ability. But what does it really mean to be a sloth? The answer is surprisingly simple: Being slow is an incredibly successful strategy for survival. In general, most folivores will compensate for a low-calorie, leaf based diet by consuming relatively large quantities of food. Although they might look quite large, most of a sloths visual mass comes from their coat of unusually thick fur probably another method of maintaining body heat. Underneath all the hair, sloths are surprisingly skinny. The difference lies in the sloths large, four-chambered stomach and extremely slow rate of digestion. I have heard it all. This means that sloths are probably surviving on the very edge of their energy budget — and therefore everything that they do has to be constantly geared towards saving energy. In fact, being slow has helped sloths to survive on this planet for almost 64 million years.

When you imagine a sloth, you probably think of a simple, sloth eating leaves creature that does very little other than sleep all day. For example, howler monkeys consume three times as many leaves per kilogram of body mass as sloth eating leaves. But in order to understand exactly what it is that makes them so slow and why it works so well, we have to sloth eating leaves at the biology of these unusual animals in a little bit more detail.

Posted in: General. The first piece in the puzzle to understanding the sloths slow pace is their low calorie diet. Similar to many poikilothermsthey rely on behavioral methods see more thermoregulation basking etc.

For the majority of mammals, digestion rate scales with body size, so larger animals should take longer to digest their food.

Why are sloths so slow? Sloths appear to break this rule quite spectacularly. Why are they so slow? And why does it work? An obvious example of such energy saving brilliance can be seen when we look at the sloths body temperature. The exact rate of digestion remains unclear, but current estimations range from hours to 50 days 1, hours for the passage of food from ingestion to excretion! This means that food intake and energy expenditure are likely limited by digestion rate and room in the stomach. It is obviously a winning tactic. In addition to a low and variable body temperature, sloths have also sacrificed muscle tissue.
