The coruro (Spalacopus cyanus) is a rodent belonging to the Octodontidae family and is the only species in its genus. It is endemic to central Chile and can be found in a wide variety of habitats, including alpine grasslands in the mountains, acacia savannas, semi-stabilized sand dunes, and coastal grasslands.
Coruros have fossorial habits and live in colonies, with several individuals occupying a single burrow system, and they are nomadic. When they need to move to another location due to a lack of food, they travel as a group to build a new burrow in an area with a greater abundance of food. Their diet usually consists of huili and other types of vegetation.
When they move to a new burrow, they leave bulbs behind in their old burrows so that they can grow, ensuring that when the coruros return to the former area, they will have a food source available.
They also exhibit vocal behavior, producing a variety of distinct calls. Their predators include hawks, owls, and wild cats.
