In public estimation and scientific investigations, sloths have undergone an astonishing transformation in the course of the past few years. Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are "masters of the alternative lifestyle".
