Abstract
Published information on the histology of the gastrointestinal tract of peramelids is limited, with previous research only examining portions of the tract. We examined the histological structure of the gastrointestinal tract of eight adult I. macrourus from stomach to colon. The organisation of the tissue layers of the gastrointestinal tract was comparable to other mammals. In contrast to previous research, the long villi in the small intestine, which accounts for half of the total length of the gastrointestinal tract in an adult I. macrourus, were folded in a zig-zag formation. The purpose of this morphological strategy is unclear.
