All The Information You Need To Know About The Armadillo

If you’re new to armadillos, you’re probably wondering a few basic facts. These insectivores are nocturnal, have a strong odor, and are vulnerable to human diseases.

Read on to learn more about these unique creatures! The Armadillo lives in the wild, although it’s usually found near water sources.

They like to drink water and lap it like dogs. Armadillos also like to cool off and wallow in mud, just like pigs and other creatures.

Armadillos Are Insectivores

While armadillos are primarily insectivores, they are also polygynous. Female armadillos have a distinctive reproductive trait; they give birth to quadruplets of the same sex.

These young are born physically identical to their mothers. Nine-banded armadillos give birth to four genetically identical pups during their first year of life.

Male and female armadillos typically share home ranges, though breeding males sometimes use areas that are exclusive.

Both males and females aggressively protect their territories. Female armadillos commonly display aggressive behavior during the breeding season.

These little creatures are nocturnal and spend most of their time near vegetation. Their prescribed home ranges are approximately 4.7 ha, which spirals inward in captivity.

They have multiple burrows in sand dunes, where they can rest and forage. This means they are often a threat to land-based predators, which they avoid.

However, when they are threatened by predators, they will retreat to these burrows and stay out of sight. Most armadillos are insectivores, meaning they eat 90 percent of their food. These little lizards dig for their food by burying their snouts in the dirt.

They also eat insects, termites, eggs, small vertebrates, and plants. While they tend to feed on small insects, they also eat dead animals. So, they are great swimmers.

They Are Nocturnal

The armadillo is a nocturnal animal, sleeping at night in its underground burrow. Unlike other burrowing animals, armadillos are not territorial about their burrows.

If an armadillo burrows in an abandoned space, chances are it will be shared with other animals. Armadillos feed on insects, small reptiles, amphibians, and plant matter.

The nine-banded armadillo breeds in July and August, having a 120-day gestation period. The armadillo is nocturnal year-round, but the nine-banded armadillo will change its behavior during cooler months.

When temperatures are cooler, it will emerge from its burrow to bask in the sun. In the late spring and early summer, armadillos will breed, with each egg breaking into four identical zygotes and yielding quadruplets.

Although armadillos are largely nocturnal, they do emerge from their burrows to feed during the day. These nocturnal creatures are deep burrowers, with burrows up to seven feet deep.

In addition to digging, armadillos also mark their territory by excreting urine and feces. In northern climates, armadillos are much more active during the day than during the night.

During early migrations, the armadillo would hold its muzzle above the surface of the river to hunt for insects and other food. The muzzle would be elevated during later crossings.

When it comes to eating, the armadillo does not interact with humans. They will hunt for food and water during the day, but at night, they sleep for as long as 16 hours. It does not like to interact with people.

They Have A Strong Odor

Did you know that armadillos have an odor? Their odor comes from glands in their anus. The glands are about one-fourth inch in diameter and three-eighths inch long.

They are present in both sexes, and the odor increases when the animal is stressed or struggling. Despite their odor, few people can stomach eating armadillo meat.

To get rid of armadillos, you can spray the area with ammonia or mothballs. Mothballs are a strong chemical, but you can also use Windex, which has a mild ammonia scent.

Ensure that you spray the area before the animal burrows in. This is a good way to dissuade armadillos and other animals from your property.

There are several ways to get rid of armadillos, including trapping them. Armadillos also release a strong odor when they urinate.

While it is impossible to prevent armadillos from urinating in a confined space, they are known to urinate in the open, where the smell is released.

The strong odor is a reaction to the urination and excretion of dead skin cells. While the best solution to preventing armadillos is a sturdy fence, it should be extended at least a foot into the ground.

Otherwise, armadillos will burrow under the fence. Another way to get rid of armadillos is to create a smelly yard. Armadillos do not like the smell of ammonia, vinegar, or mothballs, so you should keep them away from these substances.

They Are Vulnerable To Human Diseases

An armadillo is a small rodent that can transmit a wide range of human diseases.

One of these is leprosy, which is the root cause of a few dozen reported cases of the disease in the U.S. each year. Armadillos are susceptible to both leprosy and the more common disease, Hansen’s disease.

While it’s difficult to study armadillos and the transmission of human diseases, a recent genetic study published in the New England Journal of Medicine suggests that the disease is spread by armadillos and human-infected individuals.

One example of an armadillo that is prone to catching a disease is the common three-banded armadillo, which is found in the southern United States.

It is highly susceptible to leprosy, and this is largely due to its unusually low body temperature of 90@ Fahrenheit, eight degrees lower than that of humans.

The low body temperature promotes the growth of the disease-causing bacterium Mycobacterium leprae, which affects the extremities. Humans can’t survive at 98@ Fahrenheit, so an experimental vaccine is only partially effective.

However, it is worth pointing out that about 20 percent of armadillos have M. leprae, making it important to protect our wildlife from these diseases.

Despite their potential risk of disease transmission, armadillos have been traditionally used as food, clothing, and musical instruments. They are also considered an important symbol in many cultures.

In the 1902 children’s book “Just So Stories”, Rudyard Kipling introduced armadillos to prominence as a symbol of cleverness. In addition to being edible, armadillos are also vulnerable to many different diseases, including leptospirosis.

They Are A Threatened Species

The Armadillo is a species of lizard native to South America, Central America, and the U.S. The only exception is the nine-banded species, which is found in parts of the United States.

Though these creatures are considered to be endemic, they are becoming increasingly rare and have little hope of surviving in the future.

They prefer areas with dry, loose soil, where they can burrow more easily. The armadillo is an omnivore. They eat a variety of plants, insects, small vertebrates, and grubs.

They also eat eggs, vegetation, and fruits. The species does not appear to be endangered, but the food source it eats is very diverse. Armadillos also feed on dead animals and eggs.

While they are not listed as endangered, the armadillo is in decline. The armadillo has several protective methods. They use sharp claws to dig, which they use to find grubs or build burrows.

Their burrows may be as deep as 20 feet deep, which makes them excellent hiding places. Although no detailed information is available on reproduction, some researchers have observed that the armadillo rolls itself into a ball when threatened.

The Armadillo can live for twelve to 20 years. In addition to its habitat, the armadillo is vulnerable to human activity. Humans have tended to target only animals that are cute or easy to catch.

While it is true that armadillos are adaptable and resilient, the loss of their habitats has increased their chances of extinction. As a result, their numbers have declined to extremely low levels. Andean hairy armadillos are endangered in the wild.

They Are Captured As Pets

Though only a few armadillos are captured in captivity, they can be difficult to care for and require special handling.

While the armadillo is not a domesticated animal, many states prohibit the keeping of armadillos as pets. The armadillo is the only known species that can be found in the wild to harbor the bacterium that causes leprosy.

Though armadillos are naturally solitary, humans have made them into pets for their lovable behavior and for their beautiful colors.

Armadillos are shy animals, so they are not very aggressive. They may appear unaware of their surroundings and be partially closed or buried in vegetation when they are seeking food.

When they are alerted by something, they will stand up on their hind legs and brace their tails. They can also stare directly at people if they are still, but will not react to their scent or movement.

Armadillos are not very common as pets, but they can grow as large as a medium-sized dog. The odor of an armadillo is so powerful that it cannot be kept in a house.

The best way to capture an armadillo is to place a trap near its burrow entrance. It is also helpful to place two long boards on each side of the trap to increase the trap’s chances of catching the animal.

Potential and Challenges of Applying Gene Editing Techniques, such as CRISPR-Cas9, in Bovine Embryos Generated by IVF

Author:

CARLOS AUGUSTO DELMINDO FILHO

In vitro embryo production (IVP) has revolutionized cattle reproduction, allowing for the rapid multiplication of genetic material from high-value animals and opening up new possibilities for genetic improvement. Gene editing, with emphasis on the CRISPR-Cas9 technique, emerges as a powerful tool to enhance IVP, enabling precise manipulation of the genome and the introduction of desirable characteristics in animals. Gene editing techniques, such as CRISPR-Cas9, ZFNs, and TALENs, allow for precise modification of DNA at specific locations, representing an advance over homologous recombination techniques, which are inefficient and time-consuming.

However, the application of gene editing in bovine embryos generated by IVF still presents technical challenges, such as low efficiency and the occurrence of mosaicism, in addition to ethical and regulatory considerations that need to be addressed. This article discusses the potential and challenges of gene editing, focusing on the CRISPR-Cas9 technique, in bovine embryos produced by IVF, aiming to develop strategies to overcome barriers and ensure the safe and responsible application of this promising technology.

Potential of Gene Editing in Bovine Embryos

CRISPR-Cas9 gene editing allows for precise manipulation of the genome, opening up a range of possibilities for genetic improvement in cattle. The technique can be used for:

Correction of disease-causing genes: Recessive genetic diseases, such as Bovine Leukocyte Adhesion Deficiency (BLAD), can be corrected in embryos, eliminating the transmission of the disease to future generations.
Insertion of beneficial traits: The introduction of genes of interest, such as disease resistance or production traits, can accelerate the genetic improvement process, resulting in healthier and more productive animals.
Creation of models for research: Gene editing allows for the creation of animal models to study human diseases and develop new therapies.

Challenges of Gene Editing in Bovine Embryos

Despite the potential, gene editing in bovine embryos still faces challenges:

Efficiency of editing: The success rate of gene editing in embryos is still relatively low, with the frequent occurrence of mosaicism (different genotypes in the same individual).
Editing specificity: The technique can generate unintentional mutations in other parts of the genome, with possible undesired effects.
Generation of viable animals: Gene editing can affect embryonic development and the viability of the generated animals.
Ethical and regulatory aspects: The application of gene editing in animals raises ethical questions about animal welfare and food safety, in addition to demanding a clear and consistent regulatory framework.

Strategies to Overcome Challenges

To overcome the challenges of gene editing in bovine embryos, several strategies are being explored:

Optimization of editing protocols: Optimization of gene editing protocols, such as the use of different CRISPR-Cas9 systems and choosing the ideal time for editing, can increase the efficiency and specificity of the technique.
Selection of edited embryos: The combination of gene editing with genomic selection of embryos (GSE) allows the identification and selection of embryos with the desired editing and high genetic merit, increasing the efficiency of the process.
Improvement of embryo transfer techniques: The development of more efficient embryo transfer techniques can increase the success rate in generating viable animals from edited embryos.
Ethical discussion and development of regulations: Ethical debate and the development of clear and consistent regulations are fundamental to ensure the responsible and safe application of gene editing in animals.

Conclusion

CRISPR-Cas9 gene editing represents a powerful tool for the advancement of animal production and food security, as long as it is used responsibly and ethically. The combination of gene editing with other biotechnologies, such as genomic selection, can accelerate the development of solutions for livestock challenges, such as diseases, low productivity, and adaptation to climate change. However, it is crucial that the scientific community and society engage in a constant dialogue to ensure that the application of gene editing is safe, transparent, and benefits both producers and consumers.

Gene editing, especially with the CRISPR-Cas9 technique, has enormous potential to revolutionize in vitro embryo production (IVP) and genetic improvement of cattle, opening doors to a promising future in livestock. By enabling precise manipulation of the genome, this technology allows the correction of disease-causing genes, the insertion of beneficial traits, and the creation of models for research in cattle. Overcoming technical challenges, such as increasing the efficiency and specificity of editing, along with the combination with other biotechnologies, such as genomic selection of embryos, has the potential to accelerate genetic improvement and boost IVP, resulting in healthier, more productive, and better-adapted animals to market needs.

However, the application of gene editing in bovine embryos also raises important ethical and regulatory questions. It is essential that the scientific community, together with regulatory bodies and society, establish an open and transparent dialogue to discuss the possible impacts of this technology and ensure its responsible and safe application. Additionally, the development of a clear and consistent regulatory framework is essential to ensure food safety, animal welfare, and consumer confidence in products derived from gene editing.
