The little tuco-tuco is a small rodent that spends almost its entire life underground. It digs long burrows in sandy soils and feeds on plant roots.
The little tuco-tuco differs from other tuco-tuco species by its very small body size. It is important for nature because it digs the soil, helps aerate it, and serves as food for many predators.
