Project Description

This illustration depicts the internal anatomy of the two-toed sloth Choleopus didactylus and highlights its complex stomach. Understanding the folding and orientation of the stomach of C. didactylus is important in husbandry, medical imaging and zookeeping, as very little research exists on the anatomy of this species.

The two large images depict the internal anatomy of the sloth. The first depicts the view a veterinarian would see during a necropsy and portrays the stomach in relation to the diaphragm, small intestine, and ribs. The image on the far right depicts the view observed if the stomach, small intestine, colon and pancreas were removed. The schematic drawings on the left show how the stomach folds inside the abdominal cavity and the colors of each part of the schematic stomach correspond to the label colors of the main image of the stomach. The inset in the upper left-hand corner allows the viewer to appreciate the size of the stomach ghosted inside the sloth.
