Mongolian gerbil Mongolian gerbil Meriones unguiculatus, the Mongolian gerbil or Mongolian jird, is a small rodent belonging to the subfamily Gerbillinae. It is the most widely known species of the gerbil subfamily, and is the most commonly kept as a small house pet or experimental animal. Under those conditions, it is known as the domesticated gerbil. Like the Syrian or golden hamster, it was first brought to the United States in 1954 by Dr. Victor Schwentker for use in scientific research. Forty-four pairs were caught in Mongolia and brought to England. They were described as having "squirrel colors... with long furry tails."
Flower's gerbil Flower's gerbil Flower’s gerbil ("Gerbillus floweri") is a large gerbil distributed mainly in Egypt, from the eastern fringes of the Nile delta to the Sinai Peninsula, south of El Arish. Less than 250 individuals of this species are thought to persist in the wild, but it is not considered to be at threat, since it is common within its area of habitat (18.22 km2) and nothing poses a direct threat to it. This species is found in rocky desert, sandy coastal plains, grass valleys, palm tree groves and cultivated areas. The fur on the upper parts of the gerbil's body
