The pink fairy armadillo (Chlamyphorus truncatus) is the smallest kind of armadillo. It was first described by Richard Harlan in 1825. This unique animal lives alone in the deserts and scrublands of central Argentina. It is closely related to the only other fairy armadillo, which is called the greater fairy armadillo.
Pink fairy armadillos have tiny eyes and soft, yellowish-white fur. Their flexible shells are only lightly attached to their bodies. They have a special spatula-shaped tail that sticks out from the back of their shell. These armadillos are active at night (they are nocturnal) and live by themselves (solitary). They mostly eat insects, worms, snails, and some plant parts. The pink fairy armadillo can bury itself super fast, in just a few seconds! It uses its strong claws to dig into sandy soil. This helps it hide from predators, stay safe from extreme temperatures, and save water in its dry home.
We don't know exactly how many pink fairy armadillos are left. Because of this, they are listed as "Data Deficient" by the IUCN Red List of Threatened Species. Their numbers seem to be going down because of farming and predators like pet dogs and cats. It's much harder to see them now than it was many years ago.
It's very hard to keep these armadillos alive if they are caught in the wild. They often die during or soon after being moved to new places. There is only one story of a pink fairy armadillo living for more than four years in captivity. But we don't have many scientific details about that case. Because they are so unique and rare, it's very important to protect them.

Meet the Fairy Armadillos
The pink fairy armadillo belongs to a special group called Chlamyphorinae. This group includes only two living species: the pink fairy armadillo (Chlamyphorus truncatus) and the greater fairy armadillo (Calyptophractus retusus). Both of these armadillos look quite similar. They both have very small eyes and strong front legs with big claws for digging. They are also one of the few mammals that don't have visible outer ears.
These two species are experts at living underground. They developed this underground lifestyle millions of years ago. Even though they live in different places, their similarities show they likely came from a shared ancestor. This means they are closely related. Scientists believe they split into two different species about 17 million years ago.
Both types of fairy armadillos are hard to find in the wild. They are shy and mostly active at night. Scientists are still learning about their lives and how many of them there are.
Where They Live and Their Home
Pink fairy armadillos are nocturnal animals that dig burrows. They live only in the dry areas of central Argentina. They have been found in places like Mendoza and Rio Negro. This small area is very important for them. They live in grassy areas with thin shrubs like Larrea and Portulaca. They also live in sandy plains and sand dunes.
The pink fairy armadillo is very sensitive to changes in its environment. Things like sudden temperature shifts or changes in soil quality can really affect them. To survive, they need quiet places with enough firm sand and good hiding spots. This is why it's so hard to keep them in captivity.
What They Eat
The pink fairy armadillo is a fossorial animal, meaning it lives underground. It's also a generalist and an insectivore, which means it eats many different things, but mostly insects. Its main food sources are ants and their larvae, which it finds underground. It also eats worms, snails, and other insects. If insects are hard to find, they can eat plant leaves and roots. When kept in captivity, they have been seen eating watermelon, avocado, and special insectivore food.
Appearance and Body Features
The pink fairy armadillo is very small, about 9 to 11.5 centimeters (3.5 to 4.5 inches) long. It usually weighs around 120 grams (4.2 ounces). It is the smallest living armadillo and one of the least known.
Keeping Warm and Their Shell
Their fine hair helps them stay warm in places where temperatures change a lot. Nights in Argentina can get very cold. Since the armadillo is active at night, its fur helps it keep warm while it's out of its burrow.
Armadillos are famous for their tough, leathery shells. The pink fairy armadillo also has a shell, but it's much softer and more flexible. You can even see blood vessels through its armor! This shell is only attached to the body by a thin membrane along its spine.
The pink fairy armadillo can curl up into a ball to protect its soft belly, which is covered in thick white hair. Its shell has 24 bands that let it curl up. The back part of its shell is flat, which helps it pack dirt behind it as it digs. This packing helps stop its tunnels from collapsing. The shell also helps with thermoregulation, meaning it helps the armadillo control its body temperature. Since blood vessels are close to the surface, the armadillo can change how much of its shell is exposed to the air to either keep or lose heat. Like most armadillos, they use their strong sense of smell to find each other and their food.
Life Underground
The armadillo has two huge sets of claws on its front and back legs. These claws help it dig burrows in hard soil very quickly. The pink fairy armadillo is sometimes called the "sand-swimmer." People say it can "burrow through the ground as fast as a fish can swim in the sea." Its claws are very big compared to its body size. This makes it hard for them to walk on hard surfaces.
Because they live underground, pink fairy armadillos have very small eyes. They rely a lot on their sense of touch and hearing to move around. They also have a torpedo-shaped body to help them move easily through tunnels. Their thick, hairless tail helps them balance and stay steady while they dig with their other limbs.
Dangers and Threats
Since they live underground, pink fairy armadillos have to leave their burrows when it rains heavily. This is because they could drown or their fur could get wet. If their fur gets wet, they can't control their body temperature properly. This can lead to hypothermia (getting too cold) at night. Once above ground during a rainstorm, they are in danger from many predators. Pet dogs are a big threat to these armadillos. Even their underground homes are not completely safe. Dogs, cats, and wild boars can hunt them in their burrows.
These armadillos do not do well when kept in captivity. Many die during transport from where they were caught. Most armadillos put into captivity only live for a few hours or, at most, eight days. Not a single one has lived longer than four years. Even with this high death rate, many are sold illegally as pets.
Pink fairy armadillos are very sensitive to changes in climate and loss of their habitat. They are also harmed by pesticides used on farms and by being hunted too much. Since they live in warm areas, cold temperatures can wipe out their populations. This is because they have a low metabolism and can't store much fat. As more land is turned into farms, the armadillos' burrows get plowed over. The land also becomes unlivable for them. Pesticides on farms are a big worry because these chemicals stick to ants, which are the armadillos' main food. Eating too many ants with pesticides can make them very sick. Overhunting has also made them endangered. Many people in the Americas still hunt armadillos for food. Their meat is said to taste and feel like pork.
Protecting Them
In 2006, the pink fairy armadillo was listed as "Near-Threatened" by the IUCN Red List. In 2008, it was changed to "Data Deficient." This means we don't have enough scientific information about how many there are or how they live in the wild. Scientists have confirmed that it's rare to see them in the wild. This is partly because they are nocturnal and live underground.
Researchers have found that pink fairy armadillos get stressed very easily. This makes it hard to protect them, especially if they are taken out of their natural home. Any changes to their environment, temperature, or diet can cause them stress. This is likely why they don't survive well in captivity.
Many armadillos have died during transport from the wild. Many others have only lived for a few days in captivity. There are only three known cases where pink fairy armadillos lived successfully in captivity for a longer time. These were in 1970, 1985, and 2009. In these cases, individuals lived for at least 30 months, 22 months, and 8 months.
This armadillo species can be found in some protected areas, like the Lihué Calel National Park. Both national and local laws are in place to specifically protect this species.
