Interesting facts about armadillos


Armadillos are small mammals with a shell of armored plates that protect them from predators.

There are 20 species of armadillo.

Only one armadillo species (nine-banded armadillo) lives in North America. Other 19 types live in South America.

The lifespan of an armadillo ranges from 4 to 30 years.

Armadillos live in temperate and warm habitats, including rain forests, grasslands, and semi-deserts.


They vary widely in size and color.

Armadillos can be pinkish, dark-brown, black, red, gray or yellowish in color.

Closely related to anteaters and sloths, armadillos generally have a pointy or shovel-shaped snout and small eyes.

Their whole body (head, back, legs and tail) is covered with bony plates.

Contrary to popular belief, not all armadillos are able to encase themselves in their shells. In fact, only the three-banded armadillo can, curling its head and back feet and contorting its shell into a hard ball that confounds would-be predators.

Although most armadillo species look like they are bald, they do have wiry hairs on the sides and the belly. Some people refer to the hairs as curb feelers, since armadillos can feel their way around an area at night as the hairs touch objects.

Armadillos have very poor eyesight, and use their keen sense of smell to hunt for food.

Armadillos have strong legs and sharp claws. They use their claws for digging and finding food, as well as for making their homes in burrows.

Armadillos are solitary most of the time and spend most of their time sleeping. They usually sleep up to 16 hours each day in burrows.

Armadillos are mainly nocturnal, however they may also occasionally appear during the daylight and may be diurnal in cool weather.

Armadillos are insectivores. Although most of their diet consists of insects and invertebrates, armadillos also eat fruit, eggs, and small animals. They even eat carrion.

Like anteaters, they have long sticky tongue that works perfectly when they hunt ants and termites.

Armadillos are great swimmers. They can hold their breath for 6 minutes when they dive.

They are also excellent climbers. They can climb over the fence in the case they can’t dig underneath it.

Armadillos have little body fat and thin shells, so they cannot maintain their internal temperature as most mammals do.


Usually, the only time armadillos get together is to mate or to keep warm. During cold times, a group of armadillos may hunker down in a burrow together to share body heat.

Breeding season for armadillos varies from species to species, but there are some armadillos that can reproduce year-round.

Gestation is anywhere from 2 to 5 months. Armadillos do not form bonds, and the father does not stay to help raise the young.

A baby armadillo is called a pup. Armadillos can have from 1 to 12 pups in a litter. When the pups are born, their shell is soft and gray and feels like leather. They can roll up into a ball within hours of being born. The shell hardens within a few days.
