Sloths are one of the oddest creatures I’ve encountered, but they always have a smile on their face. While their smile is easy to take note of, if you look closer you’ll find their fur is green from algae and is home to its own ecosystem of insects. This mobile ecosystem develops as sloths move so slowly. In this photo you can see the green in the fur of the adult sloth, but the baby looks quite brown.
