The pups are the first of their species to be born at the Smithsonian National Zoo, and have yet to open their eyes.
The newborn’s parents, Amber and Dylan Walter, gave birth to their young on August 11 and they weigh just 5.1 ounces and 5.6 ounces, respectively.
Since they are so young, their sexes have not yet been determined.
In pictures and a video posted by the zoo, the tiny pups fit in the palms of the veterinarian’s hands and have already begun walking.

Just like normal armadillos, the screaming hairy breed has thick armor and can curl into a ball if they feel threatened.
But there's an obvious difference: They are hairy and can scream.

Their hair color is white and light brown and grows from their scutes, or the scales that cover their armor, limbs and stomach. In addition, they will belt out a loud shriek if threatened.
The babies, who are native to South America, will be able to live up to 16 years under human care and will be on display to the public after they become larger and more accustomed to their environment.
