Armadillos are some of the most unique and intriguing creatures on Earth. With their armored shells and
peculiar habits, they stand out in the animal kingdom. Whether you’ve seen one scurrying across a road or digging in the dirt, there’s much more to these fascinating animals than meets the eye. Here are 20 things you probably didn’t know about armadillos.
1. Armadillos Are Ancient Creatures
Armadillos have been around for millions of years. Fossil records show that their ancestors roamed the Earth during the time of the dinosaurs. Today’s armadillos are smaller versions of their prehistoric relatives, some of which were as large as cars!
2. Their Name Means “Little Armored One”
The word “armadillo” comes from the Spanish term meaning “little armored one.” This name perfectly describes their distinctive bony plates, which cover their bodies like a suit of armor.
3. Armadillos Are Mammals
Despite their reptilian appearance, armadillos are mammals. They belong to the order Cingulata and are closely related to sloths and anteaters. Like other mammals, they give birth to live young and produce milk to feed their babies.
4. They Come in Many Sizes
There are about 21 species of armadillos, ranging in size from the tiny pink fairy armadillo, which is about 6 inches (15 centimeters) long, to the giant armadillo, which can grow up to 5 feet (1.5 meters) in length.
5. Armadillos Have Armor Made of Bone
Their iconic armor is made of bony plates called osteoderms, which are covered by a layer of keratin (the same material that makes up human hair and nails). This armor protects them from predators and environmental hazards.
6. They Can Roll Into a Ball
When threatened, some species of armadillos, like the three-banded armadillo, can roll into a tight ball to protect their soft underbellies. This defense mechanism makes it nearly impossible for predators to harm them.
7. Armadillos Are Excellent Diggers
Armadillos have strong claws and limbs that make them expert diggers. They use their digging skills to create burrows for shelter and to search for food, such as insects and grubs.
8. They Have Poor Eyesight
Armadillos rely more on their sense of smell and hearing than on their eyesight. Their eyes are small and not well-developed, which makes it difficult for them to see clearly.
9. Armadillos Are Insectivores
Most armadillos are insectivores, meaning their diet consists mainly of insects, ants, termites, and other small invertebrates. They use their long, sticky tongues to capture their prey.
10. They Can Hold Their Breath for Several Minutes
Armadillos have an unusual ability to hold their breath for up to six minutes. This adaptation helps them when they are digging or crossing bodies of water, as they can walk along the bottom without needing to surface for air.
11. Armadillos Are Found in the Americas
Armadillos are native to the Americas, with most species living in Central and South America. The nine-banded armadillo is the only species found in the United States, primarily in the southern states.
12. They Are Solitary Animals
Armadillos are generally solitary creatures and prefer to live alone. They come together only during the mating season or when a mother is raising her young.
13. Armadillos Can Carry Leprosy
One of the lesser-known facts about armadillos is that they can carry the bacteria that cause leprosy (Hansen’s disease). While the risk of transmission to humans is low, it’s still important to avoid handling wild armadillos.
14. They Have a Low Body Temperature
Armadillos have one of the lowest body temperatures of any mammal, ranging from 86 to 95 degrees Fahrenheit (30 to 35 degrees Celsius). This low body temperature makes them more susceptible to diseases like leprosy.
15. Armadillos Are Nocturnal
Most armadillos are nocturnal, meaning they are active at night and sleep during the day. This behavior helps them avoid predators and the heat of the sun.
16. They Have a Unique Reproductive System
Female nine-banded armadillos have a unique reproductive trait: they almost always give birth to identical quadruplets. This means that all four babies are genetically identical and of the same sex.
17. Armadillos Are Fast Runners
Despite their awkward appearance, armadillos can run surprisingly fast. When startled, they can reach speeds of up to 30 miles per hour (48 kilometers per hour) to escape danger.
18. They Are Important for Ecosystems
Armadillos play a vital role in their ecosystems by controlling insect populations and aerating the soil with their digging. Their burrows also provide shelter for other animals.
19. Armadillos Are Symbols of Resilience
In many cultures, armadillos are seen as symbols of protection and resilience due to their armored shells and ability to adapt to various environments.
20. They Face Threats from Humans
Armadillos are often hunted for their meat and shells, and they are also at risk from habitat destruction and vehicle collisions. Conservation efforts are needed to protect these unique animals and their habitats.
Armadillos are truly remarkable creatures that deserve our attention and respect. From their ancient origins to their unique adaptations, they are a testament to the diversity and wonder of the natural world. By learning more about armadillos and supporting conservation efforts, we can help ensure that these armored wonders continue to thrive for generations to come.
