Sloths have an unusual method of camouflage. Cracks in their hair allow many different species of algae and fungi to grow which makes them appear green. Some species of fungi living in sloth fur have been found to be active against certain strains of bacteria, cancer and parasites! Sloth hair also provides home to an entire ecosystem of invertebrates — some species of which are found nowhere else on earth (like the ‘sloth moth’). A single sloth can host up to 950 moths and beetles within its fur at once. https://slothconservation.org/10-incredible-facts-about-the-sloth/
