In monkeys of the subfamily of Cercopithecinae, they allow for more predigested food. [5] Cheek pouches contribute to the protection of animals by allowing them to carry their food in the pouches to shelter, allowing them to transport their food to safer locations, as they are pressing these pouches to the back of the mouth with the back of the ...
A pouch is present in most, but not all, species. 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 skin of the holotype specimen is kept at the Natural History Museum in London. [7] A yellow-colored golden hamster. In 1930, Israel Aharoni, a zoologist and professor at the Hebrew University of Jerusalem, captured a mother hamster and her litter of pups in Aleppo, Syria. The hamsters were bred in Jerusalem as laboratory animals.
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".
Chameleons - Colour change signals a chameleon's physiological condition and intentions to other chameleons. [3] [4] Because chameleons are ectothermic, they change color also to regulate their body temperatures, either to a darker color to absorb light and heat to raise their temperature, or to a lighter color to reflect light and heat, thereby either stabilizing or lowering their body ...
Because this mouse is a sensitive species, factors such as illegal trash dumping, invasive species, domestic animal predators, vehicular roadway threats, and inadequate regulatory mechanisms affect the species' well being, not to mention the elevated extinction risks that can play a common role on greatly reduced populations.

In some species, skin folds join the second through fifth toes, almost reaching the first metatarsal joint. [8] The monkey's size differs depending on sex and species. Males from all species can range from 41 to 70 cm (16 to 28 inches) in head and body length, and in weight from 5.5 to 18 kg (12.13 to 39.7 lb). [ 6 ]
