Six-banded armadillo
Euphractus sexcinctus
Mammals — Cingulata (Dasypodidae)
The six-banded armadillo is a highly adaptable mammal and one of the most generalist armadillos in South America. In Brazil, its presence is associated with open environments and transition zones, where it acts as an important soil engineer and recycler of organic matter.
A resilient generalist of open environments
Cathemeral in its activity, the six-banded armadillo has a broad diet and high tolerance for environmental disturbance. Its ecology reflects an ability to persist in both natural and human-altered landscapes, linking underground processes to the surface.
📍 Operating biomes
It occurs in the Caatinga — Brazil's dry thorn-scrub biome —, the Cerrado — the Brazilian savanna —, the Pantanal, the Atlantic Forest (in open areas), the Pampa, and the edges of the Amazon. It favors open, dry, or seasonally flooded habitats, including grasslands, agricultural areas, and human-modified mosaics.
🌍 Conservation status (IUCN)
LC · Least ConcernAccording to the IUCN, the species is classified as LC (Least Concern). Even so, it faces local pressure from hunting, roadkill, and habitat loss.

🔗 Ecological ripple effect
The six-banded armadillo's excavations increase soil porosity, promote water infiltration, and create refuges used by a variety of species. Its scavenging habit contributes to nutrient recycling.
