Sloth fur acts as a complete ecosystem, usually hosting at least two species of symbiotic cyanobacteria (which provide camouflage) and many species insects and other organisms. These range from moths, beetles, and cockroaches to ciliates, fungi, and algae. One study found 950 species of beetle living on one sloth.
