tatus

Tatus is the plural form of tatu, the Portuguese name for armadillos. In Brazilian Portuguese, tatus refers collectively to the armadillos, a group of New World placental mammals in the order Cingulata and the family Dasypodidae. The term derives from Tupi-Guarani roots and is used to describe multiple species rather than a single species.

Armadillos are medium-sized mammals characterized by a protective armor of osteoderms covering the back, head, and tail, linked by skin and flexible joints. Their bodies and limbs are adapted for digging, with strong forelimbs and sharp claws. Among armadillos, some species can roll into a ball for defense, notably the three-banded armadillo, while others cannot.

Geographically, tatus are native to the Americas, ranging from the southern United States through Central America and most of South America to parts of Argentina. They inhabit a variety of environments, including grasslands, savannas, forests, and deserts, often favoring soft soil suitable for burrowing. Diet is primarily insectivorous, supplemented by small invertebrates and sometimes plant matter, depending on species and available food.

Reproduction varies by species. The nine-banded armadillo, a well-known member of this group, is notable for giving birth to litters of four genetically identical offspring from a single egg, a phenomenon known as polyembryony. Other species show different breeding cycles and litter sizes.

Conservation status among tatus ranges from least concern to endangered, influenced by habitat loss, hunting, and road mortality. In many regions, armadillos play important roles in soil aeration and pest control, while also featuring in local culture and cuisine.
