Three Toed Sloths
There are only four different species of three toed sloths: the Brown-throated, Pale-throated, Maned, and Pygmy. They are all arboreal (live in trees), and have a reputation for being quite slow. They are, however, great swimmers. The sloth pictured here is wet because he just went for a swim.
Interestingly enough, they don't have normal teeth (kind of a molars--kind of not) called molariforms. Also interestingly, they do not maintain a constant body temperature--it fluctuates with the outside air temperature. As a result they need to live in warm, humid environments near the equator [like Panama and northern South America].
The picture is credited to Bryson Voirin and the BBC. The link to great slide show is here.
