The silver spiny mouse is a small rodent that spends almost its entire life underground. It has silvery-gray fur, poor eyesight, and powerful front paws for digging long tunnels.
The silver shrew differs from other shrew species in its silvery fur color and solitary lifestyle. It loosens the soil, which helps plants grow, and serves as food for snakes and birds.
