Early grazing horse, hindgut fermenter (composite)
Smithsonian National Museum of Natural History
Washington, DC, United States
Hindgut fermenters, like Parahippus and modern horses, have a cecum—a pouch at the beginning of their very long large intestine. Food reaches the cecum after being chewed, swallowed, and passed through the stomach. Bacteria in the cecum and large intestine ferment the food to finish the job.
