Bamboo bear

Iconic black-and-white bear of the mountain bamboo forests of central China, giant pandas can weigh up to 125 kg and spend up to 14 hours daily consuming bamboo, which comprises 99% of their diet despite belonging to the order Carnivora. Solitary and elusive, they have a pseudo-thumb for gripping bamboo stems. Downgraded from Endangered to Vulnerable in 2016 following successful conservation and breeding programs.

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.
