What is the structure and function of a sloth?

Sloths have a unique structure characterized by their elongated limbs, long claws, and a low metabolic rate, which allows them to conserve energy. Their bodies are adapted for a slow, arboreal lifestyle, with a strong grip for hanging from tree branches. They possess a specialized digestive system that efficiently processes the leaves they consume, often taking weeks to fully digest food. This adaptation helps them thrive in their tropical rainforest habitats, where they spend most of their time hanging upside down.
