Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.
