What Do Armadillos Look Like?

Armadillos look like no other mammal on Earth! Their most obvious feature is their bony armor made of overlapping plates called scutes. These plates cover their back, head, legs, and tail. The armor is made of bone covered by tough skin. Between the plates, flexible bands of skin let armadillos bend and move. The nine-banded armadillo has nine of these flexible bands across its middle!

The nine-banded armadillo is the most common species in North America! It's about the size of a large cat—roughly 25 inches long plus a 15-inch tail. It weighs 8 to 17 pounds. Its armor is grayish-brown, and its belly has soft, hairy skin with no armor. Armadillos have long, pointed snouts and large, rabbit-like ears. Their eyesight is poor, but their sense of smell is excellent!

Armadillos come in many sizes! The pink fairy armadillo is the smallest—only 5 inches long with pink, nearly transparent armor. The giant armadillo is the largest—up to 5 feet long and 120 pounds. The three-banded armadillo from South America is the only species that can roll into a complete ball. Most armadillos have strong, curved claws designed for digging through hard soil!

Where Do Armadillos Live?

Armadillos live throughout the Americas! Most species live in Central and South America. The nine-banded armadillo is the only species found in the United States. It lives from Texas and the southeastern states all the way down through Central America. Nine-banded armadillos have been spreading northward for the past century. They keep expanding their range into new areas!

Armadillos prefer warm areas with soft soil for digging! They live in grasslands, forests, scrublands, and even semi-deserts. Armadillos need loose soil where they can dig burrows and search for food. They avoid rocky ground and places with very cold winters. Their armor doesn't keep them warm, so cold weather is a big challenge for these animals!

Every armadillo digs and maintains several burrows! A single armadillo may have 5 to 15 burrows in its territory. Burrows are usually 7 to 8 feet long and 2 feet deep. Armadillos line their burrows with leaves and grass for bedding. They use different burrows for sleeping, escaping predators, and raising babies. Abandoned armadillo burrows become homes for rabbits, snakes, and other animals!

What Do Armadillos Eat?

Armadillos are mainly insect eaters! They use their excellent sense of smell to find food underground. Their long, sticky tongues slurp up ants, termites, beetles, and grubs. A single armadillo can eat up to 40,000 ants in one meal! They also eat earthworms, spiders, scorpions, and other small invertebrates. Armadillos root through leaf litter and dig in soil to find their prey!

Armadillos also eat some plants and small animals! They munch on berries, seeds, and fungi. Some armadillos eat bird eggs, small frogs, lizards, and even carrion. The nine-banded armadillo gets about 90% of its food from insects and grubs. Giant armadillos can tear open termite mounds with their powerful claws. They feast on thousands of termites at a single mound!

Armadillos forage mostly at night! They waddle along with their noses close to the ground, sniffing constantly. When they smell food underground, they dig rapidly with their front claws. Armadillos can dig through surprisingly hard soil. They leave behind small cone-shaped holes all over their territory. If you see lots of little holes in your yard, an armadillo might be visiting!

Cool Facts About Armadillos

Rolling into a ball: The three-banded armadillo is the only species that can roll into a perfect ball! When threatened, it tucks its head and feet inside and snaps its armor shut. The result is a hard, round sphere with no soft parts exposed. Predators can't bite through it or pry it open. Other armadillo species can't do this—they either run, dig, or press against the ground to protect their soft bellies!
Identical quadruplets: Nine-banded armadillos always give birth to identical quadruplets! Every time a mother armadillo has babies, she has exactly four. All four babies come from a single fertilized egg that splits into four identical embryos. This means all four babies are the same gender and genetically identical. No other mammal consistently does this!
Super diggers: Armadillos are digging machines! Their powerful front legs and curved claws can tear through hard-packed soil. When frightened, a nine-banded armadillo can dig a burrow in just a few minutes. They dig faster than most predators can reach them. Armadillos have even been known to dig straight down and disappear underground in seconds!
Holding their breath: Armadillos can hold their breath for up to 6 minutes! This lets them walk along the bottoms of streams and ponds. Nine-banded armadillos cross rivers by walking underwater on the river bottom. They can also swallow air to inflate their intestines, making themselves buoyant enough to swim across water. Walking or floating—they have two ways to cross rivers!
Jumping when scared: When startled, nine-banded armadillos jump straight up in the air! They can leap 3 to 4 feet high. This startle reflex helped them avoid predators in the wild. Unfortunately, it causes problems with cars. When a car passes over them, they jump up and hit the underside of the vehicle. This is why many armadillos are found on roadsides!
Bony armor: Armadillo armor is made of real bone! The plates are formed from bony deposits in the skin called osteoderms. These bone plates are covered by tough, keratinous skin—the same material in human fingernails. The armor protects them from thorns, branches, and many predators. However, it's not bulletproof despite popular stories!
Tiny pink fairy: The pink fairy armadillo is the world's smallest armadillo—only 5 inches long! It lives in central Argentina and spends most of its life underground. Its armor is pale pink and so thin you can almost see through it. The pink fairy armadillo is rarely seen by people. It's one of the most mysterious mammals in the world!
Designed for digging: Armadillos are perfectly suited for a life of digging! Their armor protects them from underground obstacles. Their claws are shaped like shovels. Their strong front legs provide digging power. Their pointed snouts probe narrow spaces. Their sticky tongues reach into insect tunnels. Every part of an armadillo helps it find food underground!

Baby Armadillo Facts

Nine-banded armadillo mothers always have four identical babies! The babies are born in a grass-lined burrow after about 4 months of pregnancy. All four babies look exactly alike. They're born with their eyes open and soft, leathery skin that will harden into armor over the next few weeks. Newborn armadillos are about the size of tennis balls!

Baby armadillos can walk within hours of being born! Their soft armor gradually hardens over the first weeks. Mother armadillos nurse their babies for about 2 to 3 months. The four identical siblings stay together with their mother during this time. They follow her on nightly foraging trips, learning where to find food!

Young armadillos start digging and hunting insects at a young age! By 2 to 3 months old, they're eating solid food alongside their mother's milk. The four siblings often stay together even after leaving their mother. They may share burrows and forage in the same area. Young armadillos reach adult size at about 1 year old!

Baby armadillos face threats from coyotes, dogs, bears, and large birds of prey! Their soft armor provides less protection than an adult's. Running and diving into burrows are their best defenses while young. Armadillos become able to breed at about 1 year of age. In the wild, they typically live 7 to 10 years. In protected environments, some reach 20 years!

Why Are Armadillos Special?

Armadillos are the only mammals with bony armor! While pangolins have scales and porcupines have quills, only armadillos have actual bone plates in their skin. This unique defense has served them well for a very long time. Armadillos prove that nature creates many different ways to protect animals from danger!

These digging experts help ecosystems in many ways! Their burrows provide shelter for dozens of other animal species. Their digging aerates soil and mixes nutrients. By eating huge numbers of insects, armadillos control pest populations. Fire ants, termites, and beetle grubs are all on the menu. Armadillos are hardworking members of their ecosystems!

Armadillos are expanding their range across the United States! Nine-banded armadillos have been moving northward for decades. They've been spotted as far north as Illinois and Nebraska. Climate conditions and their adaptable diet help them colonize new areas. Watching armadillos spread is a real-time example of animal range expansion!

These armored animals remind us of nature's creativity! An animal that wears bone armor, always has identical quadruplets, walks underwater, and can jump 4 feet in the air sounds made up. But armadillos are very real. From the tiny pink fairy armadillo to the powerful giant armadillo, this family shows incredible variety. Next time you see an armadillo waddling through your yard at night, remember—you're watching one of nature's most unique designs!
