- The Euphractus sexcinctus, commonly known as the yellow or six-banded armadillo, is a distinctive armadillo species found throughout much of South America. This medium-sized mammal typically measures 40-50 centimeters in body length, with an additional 15-25 centimeters of tail length, and weighs between 3.2 to 6.5 kilograms.
- The species gets its name from the six prominent, flexible bands of armor that run across its midsection, though the actual number can vary between six to eight bands. The carapace is yellowish-brown to gray in color, giving rise to its common name “yellow armadillo.” Unlike some other armadillo species, Euphractus sexcinctus cannot roll into a complete ball for protection, instead relying on its strong claws and digging ability to escape danger.
- These armadillos are opportunistic omnivores, displaying a more varied diet than many other armadillo species. They consume insects, larvae, small vertebrates, plant matter, carrion, and even occasionally birds’ eggs. Their powerful claws and robust build make them excellent diggers, allowing them to both forage for food and construct burrows for shelter.
- Euphractus sexcinctus is primarily nocturnal but can also be active during daylight hours, particularly in cooler weather. They are solitary animals, coming together only for mating purposes. Females typically give birth to one to three young after a gestation period of approximately 60-65 days. The young are born with soft leather-like skin that gradually hardens into the characteristic armor.
- The species has adapted well to human-modified landscapes and can be found in various habitats including grasslands, savannas, and even agricultural areas. Their range extends through Brazil, Paraguay, Uruguay, northern Argentina, Bolivia, and parts of Peru. Despite facing pressures from habitat modification and hunting, their populations remain stable across much of their range.

- The Zaedyus pichiy, commonly known as the pichi or dwarf armadillo, is a small armadillo species native to South America. This compact armadillo typically measures 26-34 centimeters in body length with a tail length of 11-13 centimeters, making it one of the smaller armadillo species. Adults typically weigh between 1 to 2 kilograms.
- The pichi’s carapace is dark brown to blackish in color, with pale yellow or white edges along its scutes and bands. It possesses 6-8 movable bands in its midsection, allowing for some flexibility in movement. The head shield is triangular in shape, and the tail is covered in small plates. Unlike many other armadillos, the pichi has the unique ability to roll into an almost complete ball when threatened, offering protection from predators.
- This species is particularly well-adapted to cold climates and is the southernmost-dwelling of all armadillo species. It inhabits arid and semi-arid regions, including grasslands, steppes, and shrublands of Argentina and Chile, from sea level up to elevations of 2,500 meters. The pichi has developed the remarkable ability to enter a state of torpor during cold winter months, making it one of the few armadillo species known to undergo this form of hibernation.
- Zaedyus pichiy is primarily insectivorous, feeding mainly on ants, beetles, and their larvae. However, they are opportunistic feeders and will also consume plant material, small vertebrates, and eggs when available. They are excellent diggers, using their powerful claws to excavate burrows for shelter and to search for food.
- The species is primarily diurnal, being most active during daylight hours, particularly in the morning and late afternoon. They are generally solitary animals except during the breeding season. Females typically give birth to one or two young after a gestation period of around 60 days. The young are born with soft, leather-like skin that gradually hardens into armor.
- Conservation concerns for the pichi include habitat loss due to agricultural expansion, hunting for food and local trade, and the impacts of climate change on their habitat. Their population has declined in some areas, leading to increased conservation attention for this unique armadillo species.
