Difference between Armadillo and Pangolin


Armadillos and pangolins are often confused with one another since they both have a tough outer covering. Due to their similar habits and diet, they are frequently lumped together with anteaters. Physical appearance, environment, taxonomy, behaviour, and reproduction are all key areas where these two animals diverge significantly.

What is Armadillo?

These placental mammals, whose name means "small armored on," includes 21 living species and nine extinct ones. All armadillo species are endemic to the Americas and are classified in the cingulate order of the Xenarthra superorder. There are 21 species with varying sizes, according to the Integrated Taxonomic Information System. The Giant armadillo, which is approximately 5 feet in length, is the biggest of the armadillo species, while the pink fairy armadillo, which measures about 6 inches in length, is the smallest.

Nine genera and 21 species of armadillos exist, including the pink fairy, seven-banded, screaming hairy, northern naked-tailed, nine-banded, Brazilian three-banded, larger fairy, six-banded, and gigantic armadillo.

The armadillo is barrel-shaped, has short legs, and can move remarkably quickly. They feature long, pointed claws and a leathery armor shell comprised of plates that overlap at the head, tail, back, and legs. They are also characterized by long sticky tongues and pointy snouts. The three-banded armadillo is the only species that can roll into a hard, armored ball for protection against predators, unlike other armadillos, who defend themselves by hastily excavating a hole. Because of their limited vision, these animals rely on their keen sense of smell to hunt.

The lack of fat in their bodies means that they can only survive in warm climates, therefore, they tend to cluster around the equator. They are nevertheless highly fussy about the habitats, and frequently base it on the kind of soil with a predilection for loam or sandy soils for easy burrowing and digging. Except for the nine-banded armadillo, which may be found from the southern United States to Argentina, all armadillo species are found in South and Central America.

While armadillos mostly eat insects and larvae, they also consume plants, eggs, and even fruit, making them omnivores. They can collect termites, ants, and other insects because of their long, sticky tongue. They have a gestation duration of 2-5 months and commonly give birth to 1-12 pups in clutches.

Although certain species are not in danger of extinction, their number has dropped by more than 30% in the last 21 years, including the Andes hairy armadillo.

What is Pangolin?

Pangolins, or scaly anteaters, belong to the extremely peculiar order Pholidota of placental mammals. Though their scaly appearance leads many to mistake them for reptiles, pangolins are actually mammals. Their unique appearance is the result of epidermal scales emerging from a thick underlying skin.

Even though they lack teeth, pangolins can nonetheless grind up their food with the help of their strong muscles and some small stones they keep in their stomach. You may see pangolins all throughout Southeast Asia and in the subtropics of Africa.

Differences: Armadillo and Pangolin

The following table highlights the major differences between Armadillo and Pangolin −

Characteristics

Family

Armadillos belong to the enigmatic Cingulata order, which itself belongs to the ancient and wildly diversified Xenarthra superorder, which also includes ground sloths and armoured mammals.

The order Armadillidae has around 20 extant species of armadillos.Dasypodidae is the family that contains armadillos.

Pangolins, often known as scaly anteaters, belong to the family Manidae of the placental mammal order Pholidota. It's safe to say that pangolins are one of the most peculiar animal families.

Morphology

Armadillos are unique among mammals because of their tough exoskeleton and powerful digging claws. Its protective covering, known as a carapace, is brown and as sturdy as a suit of armour.

One of the most recognisable aspects of an armadillo is its integument. The name translates to "small armoured one" from the Spanish, a nod to the bony plates that make up majority of the animal's exterior.

Pangolins, often known as scaly anteaters, are easily identifiable by the armour of overlapping epidermal scales that cover their whole bodies. They are unique among mammals in having armour that develops from their thick dermis.

Physical Features

The armadillo is a big mammal with a long tail and short, scaly legs. Small, sharp eyes sit atop long, snub noses in this species. On an average, armadillos measure around 75 cm (about 30 inches) in length (tail included) and weigh between nine and sixteen pounds.

The maximum length of the enormous armadillo is 150 cm. The enormous armadillo is a deep brown, while the pink fairy armadillo is a gorgeous salmon tint.

Depending on their size at birth, pangolins can range in weight from 3.5 to 73 pounds. The biggest living pangolin species is the huge ground pangolin.

Without teeth, pangolins must rely on their strong muscles and the little stones they store in their stomach to break down their meal.

Habitat and Diet

Rain forests, grasslands, semiarid regions, and other types of wooded habitats are typical warm-climate homes for armadillos. Some people want to settle down near water, specifically rivers and streams.

Locations where you're most likely to find them include southern USA, Central America, and South America. Outside of South America, you won't find any armadillos unless you count the nine- branded variety. The nine-banded armadillo is the only member of the Xenarthra family found in North America. They consume various insects such as ants, beetles, and termites.

The savannah, tropical woods, and dry woodlands are all sandy environments that pangolins call home. They prefer to locate near bodies of water. The pangolin's range includes much of Africa, from the south to the east.

The Indian pangolin, the Chinese pangolin, the Sunda pangolin, and the Palawan pangolin are the four species of pangolin found in Asia.

The ground pangolin, the gigantic pangolin, the white-bellied pangolin, and the black-bellied pangolin are all species of pangolin found in Africa. Ants and termites are the mainstays of the pangolin's diet.

Reproduction

During the late summer, between the months of June and September, armadillos have their mating season. Unlike other mammals, the fertilised egg (zygote) in a female armadillo floats freely in the uterus for some time before it is implanted.

A two-year delay has been observed, although normally this takes three to four months. The fertilised egg divides into four zygotes, each of which develops into a new human being.

Male and female pangolins are only thought to interact socially during mating season due to the species' reputation as a loner. The mating season occurs once a year, often in the late summer or early fall.

The tails of the male and female become intertwined during the copulation process. Women typically only have one child and a pregnancy lasts around 140 days.

Conclusion

In conclusion, while armadillos and pangolins may appear similar at first glance, they have many unique differences that set them apart. They have different physical characteristics, habitats, and behaviors, and are facing different threats to their populations. It is important to understand and appreciate the differences between these two animals in order to better protect and conserve them for future generations.
