TIME magazine claimed lemurs are the only species "that stands a chance of deposing the sloth's pop-culture reign." The Malagasy people call lemurs "the ghosts of the forest" because of their haunting stares (lemur in Latin means “ghost”) but that psychotic gaze is part of their charm!
As primates, they are our distant relatives, and live in social groups called troops that are dominated by females. There are 30 living species of the lemur, all of which are unfortunately endangered or vulnerable due to deforestation. Here's a link to groups working to preserve these weird and wonderful animals and their habitats.
But sloths! They're basically hammocks with faces! Blessed with extremely slow metabolisms, sloths spend 70 percent of their time resting in the trees. (Fun fact: It takes a sloth one whole month to digest a single leaf.) Sloths do everything upside down—eat, sleep, mate, and even give birth. (Check out the Sloth Conservation Foundation if you'd like to learn more and help conserve these sleepy creatures.) According to Slothville:
Sloths’ closest relatives are anteaters and armadillos. Together they belong to an ancient group of mammals called the Xenarthra, which makes them sound like they come from outer space and they have the sci-fi looks to match.
Lemur babies ride on their mothers' backs for the first five months of their lives. Look at those cute hands! We're dying!
Baby sloths! Though they are wild animals, they are instinctively friendly towards humans.
