Problem statement: The anatomy of the gross intestine and its mesentery of the capybara (Hydrochoerus hydrochaeris) have not been described completely. Approach: In the present study, eight adult capybaras were studied using gross dissection. Results: The cecum was the largest part of the intestine and was divided into base, body and apex. The cecocolic fold joined the cecum to the full extent of the proximal loop of ascending colon. The ascending colon was divided into two ansae, one proximal and one distal or spiral. The distal ansa had a spiral arrangement and was placed cranially to the right, covered ventrally by the apex of the cecum. This ansa had a centripetal gyrus to the left, a central flexure and a centrifugal gyrus turning to the right that was continuous with the transverse colon in the right colic flexure. Conclusion: The gross intestine of the capybara was different to other previously studied rodents.
