The steppe mouse is a small rodent with a long tail that lives in open steppes and fields. The body length of an adult is about 10 centimeters, and the weight is 25 grams.
The steppe mouse differs from the forest mouse by its lighter coloration and love for open spaces without trees. It serves as food for many predators and helps spread plant seeds.
