twenty hours every day. even though sloths are lethargic, they manage to stay safe by living in the treetops of south and central america. sloths have special qualities that help them spend their lives hanging from branches.
for example, sloths long fur grows in the opposite direction from that of most animals. most animals fur grows downward, which helps rainwater run down off the animal. sloths fur, however, grows upward. when a sloth is hanging upside down, rainwa still directed off its body. this helps the sloth dry off more quickly. sloth fur has a special purpose. each strand of fur has grooves that collect algae. the algae give sloth a greenish color, which helps it blend in with its leafy environment. along wi sloths slow movement, this disguise makes sloths hard for predators to spot.
sloths also have long, curved claws on their front and back legs. sloths can use th claws to protect themselves from predators. more importantly, the long, sharp cla curve around branches for a powerful grip. in this way, sloths claws keep them fr slipping and falling out of trees.
hanging upside down all day can be hard for other reasons. in most animals, hang would cause the stomach, heart, and other organs to press on the lungs. not for s though. sloths have special bands of tissue called adhesions that help attach certa organs to the rib cage. these bands of tissue hold the organs in place so they don press down on the sloths lungs. thus the sloth stays healthy and comfortable whil hanging in its upside - down world.
