Feeling slothful

I am feeling really slothful today though I have heaps to do before I go to Australia  – both here at work and at home! But which type of sloth am I?

Sloths are extremely slow-moving mammals found in the rainforest canopies of Central and South America. Most sloths are about the size of a small dog and they have short, flat heads. Their hair is grayish brown but they can look grey-green because they move so slowly that tiny camouflaging algae grow all over their coats!! (doesn't that sound delightful??).  Their huge hooked claws & long arms allow them to spend most of their time hanging upside down – mothers also give birth to babies whilst hanging upside down!!!

Sloths have made extraordinary adaptations to their arboreal lifestyle. Leaves provide little energy or nutrition and do not easily digest – so sloths have a very large specialised, slow acting stomach with multiple compartments where symbiotic bacteria break down the tough leaves.  Up to 2/3rds of a well-fed sloth's body-weight consists of the contents of its stomach because the digestive process can take longer than a month to complete.

They have very low metabolic rates (less than half of that expected for a creature of their size), and maintain low body temperatures when active (30 to 34 degrees Celsius or 86 to 93 degrees Fahrenheit), and still lower temperatures when resting – they sleep from 15-18 hours per day so that is a lot of resting!!

Sloths move only when necessary and even then very slowly: they have about half as much muscle tissue as other animals of similar weight.  They mostly move at 15-30 cm (.5-1 feet) per minute but they can move at a higher speed if they are in immediate danger from a predator (4.5 m / 15 feet per minute).  On the ground their maximum speed is 1.5 m or 5 feet per minute.  They come to the ground to urinate and defecate only about once a week!  (given their speed of travel this must be quite an outing!).

The photo is a bit blurry because the light was low (they are nocturnal); I was taking the photo through glass and most unbelievably – the sloth was moving!!!! (look at that action!!)


Then there is Sloth in the Christian moral tradition, sloth (Latin: acedia, accidia, pigritia) is one of the seven capital sins or deadly sins. They are called the capital sins because they destroy charity in one's heart and thus may lead to final impenitence and eternal death. Sloth is defined as spiritual and/or actual apathy or laziness.

Medieval theologian Thomas Aquinas said Sloth is "sluggishness of the mind which neglects to begin good… [it] is evil in its effect, if it so oppresses man as to draw him away entirely from good deeds." (2,35, ad 1)

Mmm……   perhaps I had better start on my tasks!

  1. I like the take it easy lifestyle of a sloth but they don't have very much that's good to eat. I wouldn't like that very much. A perpetual diet? I couldn't make it as a sloth.lol

  2. I think "slothful" is another of those wonderful words which is way under-utilised – both in usage and behaviour!
    It really was amazing to see this sloth move – he or she came all the way along the branch downwards and then took another branch up towards the top of the cage. It seemed slightly faster than the figures I quoted – but it was still slow!
