About this project

Watercolors by Erin McKenney
The shape, or morphology, of the gut makes a huge difference in what an animal can eat and digest. But gut diagrams are only available for a handful of species – and we have no idea how much one individual varies from another. By taking pictures of the guts of each animal you harvest, you can help map the unknown guts of wildlife.

Step 3: Remove the entire digestive tract from the animal, and locate the cecum.
