Tolypeutes tricinctus, commonly known as the three-banded armadillo, is a species of armadillo found in South America. Its unique physical appearance, with three bands of flexible, armor-like plates covering its body, has made it a popular subject for study and research. Other synonyms for this species include the triple-banded armadillo, the Brazilian three-banded armadillo, and the Chacoan three-banded armadillo. Despite its tough exterior, the three-banded armadillo is listed as vulnerable due to habitat loss and hunting. Efforts are being made to protect this species and ensure its survival in the wild.
