brown-throated three-toed sloth

One of the world's slowest mammals, brown-throated three-toed sloths hang inverted in the rainforest canopy of Central and South America, moving at an average speed of 0.24 km/h. Their low metabolic rate is a key adaptation to their nutrient-poor leaf diet. Algae growing in their fur provides camouflage and may harbor symbiotic fungi with antimicrobial properties. Moths, beetles, and fungi form a miniature ecosystem within sloth fur.
