Grass rats are small rodents belonging to the family Echimyidae, commonly found in grasslands and savannas. They have a robust body, long tails, and fur that helps them blend into their grassy habitats. These animals primarily feed on seeds, grasses, and other plant materials, making them herbivorous. Grass rats are known for their burrowing behavior, creating extensive tunnel systems for shelter and protection from predators. They play a vital role in their ecosystem by aerating the soil and dispersing seeds, which contributes to plant growth. Their presence can indicate the health of their environment, similar to other small mammals like mice and voles.
