Armadillos are small to medium-sized mammals known for their unique armor-like shell made of bony plates. They belong to the family Dasypodidae and are primarily found in the Americas, especially in South America and the southern parts of North America. There are about 21 species of armadillos, with the most recognized being the nine-banded armadillo. These creatures are primarily nocturnal and are excellent diggers, using their strong claws to burrow into the ground in search of insects and other food. Armadillos have a low body temperature and are known for their ability to carry the bacteria that causes leprosy, although transmission to humans is rare.
