Brown-throated three-toed Sloth, Costa Rica
Sloths are among the slowest-moving animals on Earth; they can swim but are virtually unable to walk. This makes them an easy target for jaguars, eagles and people that hunt sloths for their meat.
Brown-throated sloths have the ability to rotate their heads like owls. They can turn their heads up to 300 degrees due to their unique neck structure.Sloths evolved to expend very little energy because their diet does not provide them with a lot of calories and nutrition. Brown-throated sloths primarily eat tough, rubbery rainforest leaves. These leaves are also full of toxins (a form of protection for the rainforest trees). But sloths have developed a digestive system to handle these highly indigestible leaves. Their stomachs are multi-chambered, similar to a cow’s stomach, and house a mix of bacteria which helps to slowly break down the leaves. It takes two weeks for a sloth to digest one meal — the slowest digestion time of any mammal! and they only descend from the rainforest canopy to urinate and defecate once a week.
Sloths are specially adapted to live among the treetops. Their fur hangs upside down, running from their stomachs to their backs. This is because sloths themselves usually hang upside down. The orientation of their fur helps the rain water flow away from their body. But sloths take the risk to climb down to the ground because of a symbiotic relationship they have with the flora living in their fur. Sloth fur is rife with macro- and microorganisms like algae, fungi and moths. While these organisms benefit from having a sheltered place to live among the long coarse hairs, the sloth also gains from the relationship.
The algae provides supplemental nutrition for the sloth and tints the fur green, which helps camouflage the sloth among the leaves. The fungi helps fend off parasites known to cause diseases like malaria and Chagas disease. The moths provide fertiliser for the algae.
Another unique trait of sloths is that they rely on solar energy to regulate their body temperature. With such a slow metabolism, sloths must sunbathe in order to keep their body temperature up. In this way, sloths are similar to reptiles.
Male brown-throated three-toed sloths can be easily distinguished from females because they have a bright orange patch with a black stripe on their backs. This patch has scent marking glands that attracts female sloths. Alpha males have a larger patches than other males.
