Priodontes maximus, commonly known as the giant armadillo, is the largest species of armadillo. It inhabits tropical forests, grasslands, and savannas across South America. Notable for its large, protective shell and long claws, it primarily feeds on ants and termites. Its nocturnal nature and burrowing behavior play a significant role in soil aeration and ecosystem balance.

Priodontes maximus, commonly known as the giant armadillo, is native to South America. Its geographical distribution includes countries such as Venezuela, Colombia, Ecuador, Guyana, Suriname, French Guiana, Brazil, Bolivia, Paraguay, and Argentina. The species is primarily found east of the Andes Mountains.

The giant armadillo inhabits a variety of forested environments, including tropical rainforests, deciduous forests, and savannas. It prefers undisturbed primary forests but can also be found in secondary forests and open savannahs. The climate in these regions is typically warm and humid, with significant rainfall, although it can also adapt to drier areas.

As a nocturnal and solitary species, the giant armadillo plays a vital ecological role as a burrower, impacting soil structure and creating habitats for other species. It primarily feeds on ants and termites, which positions it as a crucial part of the ecosystem for controlling insect populations. Its adaptations include strong claws for digging and a protective shell for defense against predators.
