The intestinal tract of the white rhinoceros (Ceratotherium simun) was dissected. We observed a simple structure for the small intestine, duodenum, jejunum and ileum, and a well-developed large intestine, cecum, colon and rectus. The cecum consisted of a small chamber, whereas the colon was much enlarged; notably larger than that of the domesticated horse, which belongs to the same order, Perissodactyla. This suggests that in the white rhinoceros the cecum may be functionally replaced by the well-developed colon which may act as the main fermentation tank in this animal.
对白犀（学名：Ceratotherium simum）的肠道进行了解剖。我们观察到其小肠、十二指肠、空肠和回肠结构简单，而大肠、盲肠、结肠和直肠发育良好。盲肠由一个小腔室构成，而结肠则明显增粗，显著大于同属奇蹄目的家养马的结肠。这表明在白犀中，发育良好的结肠可能在功能上替代了盲肠，结肠可能充当了这种动物的主要发酵罐。
