Monkeys have open cheek pouches within the oral cavity, but they open out in some rodents of America. Hence the name "diplostomes" is associated with them, which means "two mouths." In some rodents, such as hamsters , the cheek pouches are remarkably developed; they form two bags ranging from the mouth to the front of the shoulders.

Fur-lined cheek pouches are a feature across the family Heteromyidae. They have openings near the mouth and extend backwards along the sides of the neck. The fur on the animal's body is in general short and fine and often matches in colour the soil of the region in which the animal lives, being some shade of buff, pale brown, reddish-brown or grey.
As members of Heteromyidae—which consists of animals surviving on seeds and grain—Pacific pocket mice have fur-lined cheek pouches externally. [2] Most of the body is covered in fur that feels silky. The coats are spineless and bristle free.
Kangaroo joey inside the pouch Female eastern grey kangaroo with mature joey in pouch. The pouch is a distinguishing feature of female marsupials, monotremes [1] [2] [3] (and rarely in the males as in the yapok [4] and the extinct thylacine); the name marsupial is derived from the Latin marsupium, meaning "pouch".
Zapodidae, the jumping mice, is a family of mouse-like rodents in North America and China.. Although mouse-like in general appearance, these rodents are distinguished by their elongated hind limbs, and, typically, by the presence of four pairs of cheek-teeth in each jaw.
Many marsupials have a permanent bag, whereas in others the pouch develops during gestation, as with the shrew opossum, where the young are hidden only by skin folds or in the fur of the mother. The arrangement of the pouch is variable to allow the offspring to receive maximum protection.
The superorder Peracarida is a large group of malacostracan crustaceans, having members in marine, freshwater, and terrestrial habitats.They are chiefly defined by the presence of a brood pouch, or marsupium, formed from thin flattened plates borne on the basalmost segments of the legs. [2]
