Neymann's grass rat is a small rodent that lives in dry grassy areas of East Africa. The animal is active during the day, runs quickly through the grass, and digs burrows in the soil.
Neymann's grass rat differs from related species by lighter fur coloration and details of tooth structure. It is important for nature as a link in the food chain: it serves as food for snakes, birds, and small predators, and also helps spread plant seeds.
