The teeth of sloths do not have roots and a surface layer of enamel, so they are classified as incomplete teeth. The skull has two sections, in one of which there is a small, almost without convolutions, brain. The stomach is divided into several parts and resembles the stomach of a ruminant animal. The spleen is not located on the left, as in other mammals, but on the right. The animal has a rather long and tortuous trachea, which provides extraordinary mobility of the neck. The liver is separated from the abdominal wall by the stomach.
