species of two-toed sloths: Choloepus didactylus and C. hoffmanni. In this work, we …

Over the last decade, we have learned much about the anatomy, evolutionary history, and
biomechanics of the extant sloths. However, most of this study has involved studying sloths …

This report continues our monographic analysis of mammalian diversity and Matses
