Hunters that use their sense of sight, such as raptors, will often bypass sloths when searching for prey because the growth of algae and fungi give the sloth's fur a green tinge, allowing them to blend into the rainforest canopy. They’re so slow that green algae grows right on their fur, helping them blend in with the trees Sloth hair is unique among mammals in that it contains microcracks, making it perfectly suited for algae growth

In fact, when viewed under a microscope, you can see algae living inside the cracks.
With their light brown fur, the green of the algae contributes to a camouflage that helps them hide among the bark and leaves of the trees they call home — and occasionally their final resting.
Their hair has grooves or cracks that have the capacity to hold water, allowing algae and fungi to grow within those grooves And an animal that benefits from this hairy ecosystem are sloth moths. Yes, algae commonly grow on the fur of sloths, forming a symbiotic relationship that provides both camouflage and nutritional benefits to the sloth while offering a suitable habitat for the algae to thrive. Among all 71 sloth individuals studied, 73% hosted algae in their fur
It was either observed by the greenish color of the fur or seen under the microscope in closer observation. Sloths host algae in their fur, which provides camouflage against potential predators The algae benefit by gaining a habitat that offers moisture and protection, allowing them to thrive. Sloths’ fur can host algae, which not only greens them but also helps them blend into the tree canopy, providing camouflage and protection against predators
By allowing algae to grow on their fur.
