What is the relationship between sloth and algae?
The scientists suggest that sloths cultivate the algae in their fur by aiding the moths’ colonization. The moths act as ‘portals’ for nutrients say the scientists, increasing the nitrogen content of the fur to help grow nutritional algae.
Do sloths have green fur?
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. Sloths blend in perfectly with the trees they live in.
