Use the paragraph below to answer the question.
Sloths are some of the most interesting animals in the world. They are slow-moving mammals that spend most of their time hanging upside down in the trees of Central and South American rainforests. They have a special kind of fur that camouflages them from their predators, and an extra-long curved claw that helps them to hang on tightly to branches. Sloths are mostly nocturnal, sleeping during the day and becoming active at night, when they forage for food. They are expert swimmers and climbers, and can move twice as fast in the water as they do on land. Sloths eat a variety of leaves, buds, and fruits, and occasionally small insects. They have an incredibly slow metabolism, and it can take up to a month for them to digest their food. Sloths are solitary creatures, but you can sometimes find them sleeping in groups or cuddling with one another. While they may seem like lazy animals, they are actually very important to the rainforest ecosystem, spreading seeds, providing homes for other creatures, and helping to keep the trees healthy. Sloths are an amazing species, and we can all be thankful that they are still around.
