Goodarzi N, Tehrani PR., Topography and morphometry of gastrointestinal tract of Paraechinus Hypomelas (Brandt, 1836), Onl J Vet Res., 22 (8):707-714, 2018. Brandt's hedgehog (Paraechinus hypomelas) genus Paraechinus is widely distributed in Asia. We describe topographic morphometric features of the gastrointestinal tract (GIT) of Paraechinus Hypomelas (Brandt, 1836) from 5 subjects. The relative macroscopic surface area of the various intestinal parts was estimated as described by Kotze et al, (2010). We found a unilocular simple stomach with glandular epithelium. The cecum was absent. No taeniae or haustra were observed in various sections of the large intestine. The large intestine was composed of an ascending, transverse and, descending colon segments constituting a simple U-shaped loop starting at the right side and ending at the left side of the abdominal cavity. Due to lack of a cecum, it was difficult to distinguish between the large and small intestines macroscopically. A simple glandular stomach along with the absence of a cecum indicates insectivorous/omnivorous feeding. Furthermore, despite a relatively elongated gastrointestinal tract, we found the surface area of the GIT to be small.
