Sloths and the Power of Algae
Sloths are slow, but they turn that into a weapon. By barely moving, they avoid attracting predators. But that’s just the start—they also grow algae in their fur, turning their bodies green to blend in with the trees. The algae even give off a slightly musty scent, helping the sloth smell more like a mossy branch than a living meal.
Even their bathroom habits are strategic. They descend from the trees only once a week to poop, minimizing their exposure to danger. Some scientists even believe the algae-fur ecosystem provides nutrients and camouflage in return. It’s the laziest, greenest mutualism in nature—and it works brilliantly.
