About Sloth
Sloths are arboreal mammals of Central and South America whose famous slowness is a fuel strategy: leaves are low-calorie, so sloths minimized every cost — low muscle mass, drifting body temperature, and digestion that can take weeks.
Six species survive in two genera — three-toed (Bradypus) and two-toed (Choloepus) — a classic case of convergent evolution. Their fur hosts algae and unique moths: a portable ecosystem.
