Foregut fermentation

Foregut fermentation is a form of digestion that occurs in the foregut of some animals such as the hamster rat, langur monkey, and the hippopotamus.^[1] It has evolved independently in several groups of mammals, and also in the hoatzin, a bird species.

Foregut fermentation is employed by ruminants and pseudoruminants, some rodents and some marsupials.^[2] It has also evolved in colobine monkeys and in sloths.^[3]
