Description | Description:Also known as groundhogs, these are the most widespread marmots in North America. They vary in color from gray, reddish brown, to dark brown and have long hind legs. | Description:Hoffman’s two-toed sloth lives in tropical forest trees of Nicaragua, Peru, Central Brazil, and northern South America. They spend their lives hanging upside down: eating, sleeping, mating, and even giving birth in an upside down position. Walking is not in their nature, so they only crawl when on ground. |
