The dark field rat, or Canfield's rat, is a medium-sized rodent that lives in fields and plantations in northeastern Australia. It has a compact body, short dark fur, and strong teeth for eating plants.
The dark field rat differs from other Australian rats by its darker fur and love for damp fields and plantations. It serves as important food for snakes, owls, and other predators and helps mix the soil.
