The giant armadillo is the largest armadillo species, and they have up to a dozen or more hinged bands to protect their body. These armadillos can have from 80 to 100 teeth, and their teeth are all similar in appearance. Despite having many teeth that grow constantly through their life, giant armadillos feed mainly on termites and ants. The interesting thing is that they are capable of consuming the entire population of the colony in a single feeding session. Plus with their large claws, they are able to demolish even the hard-baked termite mounds in just minutes.

Giant armadillos inhabit areas with high termite populations around rainforest (both tropical and subtropical), floodplains, grasslands, semi-arid, and arid woodlands. They are nocturnal so they spend of their day inside burrows since they are active mostly at night. Unlike some other species of armadillo, this one cannot roll into a ball to protect itself from attack at all. Instead, it will try to flee or dig itself a burrow in which to hide. When cornered, it will raise itself on its hind legs using support from its tail and extend its front claws, ready to attack.

With their size, a single giant armadillo supplies a great deal of meat which is why people hunt them. These armadillos are also the primary source of protein for some indigenous people as well. In some other cases, people captured them for trade on the black market which they usually die during transportation or captivity. Giant armadillo is not classified as vulnerable, and there is mitigation to reduce the threat of their habitat loss and population decline.
