Armadillos are small to medium-sized mammals found in the Americas. The majority of armadillo species are found in South America, while a few species are found in North America and Central America. The Spanish word “armadillo,” which alludes to the presence of bone plates covering their bodies, translates to “little armored one.” They are characterized by their armored shells, which protect them from predators.

There are over 20 different species of armadillo, including the three-banded armadillo, the six-banded armadillo, and the nine-banded armadillo. The nine-banded armadillo is the most common species found in North America. This odd-looking creature is the only living mammal that wears such shells.

Because the shell of the young has not yet hardened, they are incredibly susceptible to predators when they are born. They are better protected by armor from predators like alligators, black bears, and mountain lions. Because they are nocturnal, nine-banded armadillos spend their waking hours feeding or burrowing. In the wild, nine-banded armadillos typically survive for 7 to 20 years. One armadillo in captivity lived for 23 years.

Armadillo Shell

Armadillo shells are made of keratin, the same protein that makes up human fingernails and hair. The shell is attached to the animal’s skeleton and is covered with skin. They have sharp claws that they use for digging burrows and foraging for food. The shell of an armadillo provides protection from predators and from the elements.

They are able to roll up into a tight ball when threatened, which protects their soft underbellies from attack. The shell of an armadillo is also used in traditional medicine. In some cultures, the shell is ground up and used as a treatment for various ailments.


The nine-banded armadillo is becoming more common. Roadways have made it simpler for them to go to other areas because humans have eliminated the majority of their natural predators. When startled, nine-banded armadillos have a propensity to leap straight up into the air, which frequently results in their death on highways.

Cars can easily drive right over them because they are so little, yet they leap up and strike the undercarriage of moving vehicles. Additionally, they are poisoned, shot, or captured by those who view them as agricultural and lawn pests. Some are consumed, while others are sold as trinkets.

Armadillo Behavior

They are nocturnal animals, meaning they are most active at night. During the day, they sleep in burrows that they dig with their claws.

Armadillos are able to roll up into a tight ball when threatened, which protects their soft underbellies from attack. It’s a frequent misconception that armadillos roll away after curling up into tight balls. None purposefully decide to roll away from predators.

Only two species of armadillos from the genus Tolypeutes are capable of curling into tight balls. These are also referred to as three-banded armadillos from Brazil and the South. This level of flexibility is not conceivable in all other armadillo species due to their excessive number of plates. They are not considered to be very intelligent animals. Studies have shown that they have poor memory and little ability to learn from experience.


They are also known to be susceptible to various diseases, including leprosy and tuberculosis. Although nine-banded armadillos are native to the Southeast of the United States, their territory has been steadily moving further north for more than a century. Even as far north as Illinois and Nebraska, some have been seen.

The whole range of armadillos, which according to one study may extend as far north as Massachusetts, has not yet been discovered. Their perspective range will further expand due to climate change brought on by an increase in atmospheric carbon.

They prefer living in woodland or grassland settings in warm, moist climes. These incredible animals can easily cross even small waterways. The nine-banded armadillo can swim or “walk” along the bottom of rivers and can hold its breath for up to six minutes. Other creatures make use of their abandoned burrows.

Armadillo Habitat and Diet

Armadillos are found in a variety of habitats, including forests, grasslands, and deserts. They are native to the Americas and only species of armadillos live in South America. The diet of an armadillo depends on the species. Some are omnivorous, meaning they eat both plants and animals. Others are insectivorous, meaning they only eat insects.

The majority of the over 500 different foods that these generalist feeder armadillos seek out are invertebrates like beetles, cockroaches, wasps, yellow jackets, fire ants, scorpions, spiders, snails, and white grubs. Small reptiles and amphibians, along with the eggs of mammals, reptiles, and birds, make up a smaller portion of the diet.

The diet contains less than 10% fruit, seeds, fungus, and other plant materials. Most species of armadillos suffered from poor eyesight and use their keen sense of smell to hunt.


They use their sharp claws to dig for food. Most armadillos are not considered to be a threat to humans. However, the nine-banded armadillos are known to carry leprosy, which can be passed on to humans through contact with the animal’s skin or through eating Armadillo meat. They are also known to be a host for the bacterium that causes tuberculosis.

Armadillo Reproduction

They are solitary creatures and only come together to mate. The mating season for armadillos typically occurs during the summer months.

After a gestation period of 60-90 days, the female armadillo gives birth to a litter of two to four offspring. The young are born blind and without their armored shells.

The shell of an Armadillo hardens as the animal matures. They reach sexual maturity at one to two years of age. They have a lifespan of 10-15 years in the wild.

Armadillo Population

The Armadillo population is believed to be stable. Armadillo is not considered to be a menaced animal. However, some species, such as the three-banded armadillo, are listed as vulnerable due to habitat loss and for their hunt.


Early mammals the size of dinosaurs called glyptodonts had thick armor. It was discovered by experts that glyptodonts, a subfamily of armadillos, initially appeared 35 million years ago. Around the time of the previous ice age, they went extinct, although their smaller, less heavily armored relatives persisted.

These two-ton creatures were targeted by humans for meat. Then, using the bony carapace, they built shelters. Nine-banded armadillos are becoming more numerous. When startled, nine-banded armadillos have a propensity to leap straight up into the air, which frequently results in their death on highways.


Only living mammals with similar shells are alligator snapping turtles. Armadillos, which are related to anteaters and sloths, often have small eyes and a snout that is pointed or shovel-shaped. From the 6-inch-long, salmon-colored pink fairy armadillo to the 5-foot-long, dark-brown giant armadillo, they range significantly in length and color.

Others are colored in black, red, grey, or a yellowish hue. The biggest armadillos still alive are called giant armadillos (Priodontes Maximus), which can weigh up to 130 pounds in the wild.

They are interesting animals because of their armored shells, nocturnal habits, and ability to walk on their hind legs. They are found in a variety of habitats in the Americas and have a varied diet.

The giant armadillo is a vulnerable species according to the IUCN. Hunting for meat and habitat degradation are their main risks. These giants are also put in danger by illicit pet trade hunting. Contrary to popular perception, not every armadillo can enclose itself in its shell. The only animal that can actually do this is the three-banded armadillo, which confuses would-be predators by folding its head, back paws, and shell into a hard ball.
