Aï De Bolivie

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.

Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
