A gerbil is a small mammal of the order Rodentia.
Once known simply as "desert rats", the gerbil subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats, jerboa, and jirds, all of which are adapted to arid habitats. Therefore, most are primarily nocturnal, and almost all are omnivorous.
The word "gerbil" is a diminutive form of "jerboa", though the jerboas are an unrelated group of rodents occupying a similar ecological niche.
One Mongolian species, Meriones unguiculatus, also known as the Clawed Jird, is a gentle and hardy animal that has become a popular pet. It was first brought to the United States in 1954 by Dr. Victor Schwentker for use in research.
Gerbils are typically between six and twelve inches (150 to 300 mm) long, and their tail makes up approximately one half of their total length. One species, however, the Great Gerbil, or Rhombomys opimus, originally native to Turkmenistan, can grow to more than 16 inches (400 mm) in length. As of August 19, 2003, officials in western China's Xinjiang Uygur Autonomous Region began releasing eagles to combat the damage they say the great gerbils have done to eleven million acres (46,000 km²) of grassland. Pet gerbils usually live 2-4 years, some shorter and some longer.*

Trivia
- When a gerbil is suddenly surprised or startled it may begin thumping his back feet rythymically; this habit is to warn others of imposing danger, even if there aren't others around. It is also widely used when two gerbils mate.
- Pet gerbils are illegal in the state of California and Hawaii
- Gerbils will usually have 4 toes on each of its front feet and 5 toes on each of its back feet, the reason it has more toes on the back feet is to allow the Gerbil better balance when it is standing on its hind legs.
- Stories abound regarding the use of gerbils in sexual activities like gerbil stuffing, though these are largely thought to be mere myth.
