The pygmy three-toed sloth, also known as the monk sloth or dwarf sloth, are found on a small island off the coast of Panama. This sloth, like other sloths, is arboreal (tree-living) and feeds on leaves. It is symbiotically associated with green algae, that can provide it with a camouflage. The IUCN lists the pygmy three-toed sloth as critically endangered. Threats to the sloth's survival include timber harvesting and human settlement, that might lead to habitat degradation.
