Sloths are beloved everywhere, but without our help they could disappear forever. As the Sloth Conservation Foundation noted, 40 percent of sloths globally are threatened with extinction. This is ...
They make the previously recognized family Megalonychidae polyphyletic, with both two-toed sloths and the Caribbean sloths being moved out of that family and away from Megalonyx. Caribbean sloths are placed in a separate, basal branch of the sloth evolutionary tree.
