Preguiça-comum (Brown-throated Three-toed Sloth)

Bradypus variegatus Shinz, 1825


The Brown-throated Three-toed Sloth is approximately the size of a house cat, ranging from 45-60cm. Like all sloths it has long limbs and a small head for the size of its body. Sloths’ fur hangs ‘backwards’ compared to other mammals, lying from the stomach to their back. This enables the water to run off while it is in a tree.

Sloths do not have visible toes but instead have long claws. In this species they have three claws on each foot, which enable them to hang from the branches of trees. The brown-throated Tree-toed Sloth can also be distinguished from other species by its brown fur and upturned mouth, giving the sloth a constant ‘smile’.



This sloth and its baby - as other moms sloth during last years - was viewed for many days, almost all weeks, sleeping, resting and feeding on the leaves of this tree (Cecropia sp.), and I was able to follow the development of its puppy for nearly two months.

The Brown-throated Three-toed Sloth is found in many Central and South American countries including WLT project areas Brazil, Paraguay and Ecuador. The species was originally also native in Argentina, but has been considered extinct in this country after the last sighting in 1916.

They can live in a range of habitats and have been recorded in lowland tropical forest, cloud forest, semi-deciduous forest and montane tropical forest.



The town of the coordinates that I gave for search, is not DUQUE DE CAXIAS, as reports the search map of this page, but PETRÓPOLIS.

Thank you, armadeus.4 and Mackenzie O!

The story of this sequence of images, is summarized as follows:

1 - mother calls the puppy to come down with her and leaving that branch;
2 - puppy does not obey the mother and remains in place;
3 - mother back and makes it clear to the puppy that is an order, not a request;
4 - mother just back down when puppy follows with her, feeling his feet on her shoulders.
