The three-toed sloth (Bradypus variegatus), also known as the brown-throated sloth, is an arboreal mammal of the tropical forests of Central and South America. In Ecuador, it is found in habitats along the Coast, the Chocó, the Amazon, and the Andean foothills.
Its famous slowness is not a weakness, but an energy-saving strategy. Its diet is based mainly on leaves, along with flowers and fruits, foods that provide relatively little energy and take a long time to digest. As a result, it spends much of its life resting and moving slowly among the branches.
Its long arms and large curved claws allow it to hang securely from trees. Although it moves awkwardly on the ground, it is able to swim and spends most of its life in the canopy. Even its fur forms a small ecosystem: scientific studies have found communities of green algae growing among its hairs, which can give the body a greenish tint. This coloration may help with camouflage, although that benefit is still being studied.
The sloth comes down to the ground only occasionally, mainly to defecate and urinate, a moment when it becomes more exposed to predators. Its natural predators include large cats and birds of prey.
In a forest where many species survive by running, flying, or hiding, Bradypus variegatus follows a different strategy: use little energy, move slowly, and live almost suspended among the leaves. Its unhurried rhythm is an extraordinary adaptation to life in the treetops.
