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."
Guinean gerbil Guinean gerbil The Guinean gerbil ("Gerbilliscus guineae") is a species of gerbil found in Burkina Faso, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Mali, Senegal, Sierra Leone, and possibly Liberia. Its natural habitats are subtropical or tropical dry forests, dry savanna, rocky areas and arable land, but it is mostly found in areas laterite or clay soils, and with variable amounts of vegetation and dense scrub. This species is described as common and has a stable population and a wide distribution, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
