The North Carolina Wildlife Resources Commission shared a map on Wednesday of where nine-banded armadillos have been seen in the state.  

Confirmed observations of these armadillos have been more common in the western part of the state, but nearly every one of North Carolina’s counties have at least had an unconfirmed sighting report.

There are 20 types of armadillos, but the nine-banded armadillo is the only species found in the United States, according to the National Wildlife Federation. They get their name from the banded pattern on the armor-like plates that cover their bodies. Unlike their three-banded armadillo counterparts in South America, the ones in North America do not roll.

The first recorded sighting of an armadillo in the U.S. was in Texas in 1849, but they have been expanding their range ever since, according to research published by Bradley University.

A less fun-fact about nine-banded armadillos is that they are the only animals, besides humans, known to naturally carry leprosy, according to the Emerging Pathogens Institute.

A 2015 study by the institute found that more than 16% of armadillos in Florida carried Mycobacterium leprae, the bacteria that causes leprosy. Now known as Hansen’s disease, it is treatable and 95% of people cannot get it because their immune system can fight off the bacteria, according to the Centers for Disease Control and Prevention.

The Wildlife Commission responded to concerned comments about the armadillo’s capacity to carry leprosy.

“We don’t have evidence that armadillos in North Carolina carry the bacteria, which is easily treated by modern antibiotics,” the commission commented on Facebook. “If worried about it, just don’t touch any armadillos.”
