How do pangolins scales grow

|

Pangolin scales are made of keratin, the same protein that forms human hair and fingernails.

The scales grow throughout the life of a pangolin just like hair, and the scale edges are constantly filed down as pangolins dig burrows and tunnel through the soil in search of termites and ants

The scales are overlapping like artichoke leaves and cover most of their bodies, except for their undersides, which are covered with sparse fur

The four Asian pangolins are distinguished from the African species by the presence of bristles that emerge from between the scales.

Scale Development in Pangolins

After searching for information on the embryonic and developmental processes that pangolins go through to form scales, I found that there is limited research on this topic.

However, I found some studies that provide insights into the genetic basis underlying the differentiation of skin appendages in pangolins.

One study proposed that scale development was an innovation that provided protection against injuries or stress and reduced pangolin vulnerability to infection

Another study found that Pangolin/dTCF, a transcription factor, plays an important role in Drosophila wingless signaling, which is involved in embryonic patterning and wing development.

Unfortunately, I could not find any information on how scales develop from a cellular level in pangolins.

It seems that more research is needed to fully understand the embryonic and developmental processes that pangolins go through to form scales.

Scleroprotein in Scale Formation

After searching for information on the role of scleroprotein in scale formation, I found a study that provides insights into the molecular basis of scale formation in pangolins

According to the study, pangolin scales are composed of a unique type of keratin, which is a type of scleroprotein that forms the structural framework of the scales

The study also found that the genes encoding keratin-associated proteins (KAPs) are highly expressed in the skin of pangolins, suggesting that KAPs play a crucial role in the formation of pangolin scales.

Unfortunately, I could not find any information on how scleroprotein is produced and deposited in the scale structure.

It seems that more research is needed to fully understand the process of scale formation in pangolins.

Scales as a Defense Mechanism

Pangolin scales serve as a defense mechanism for these animals, providing protection against predators and other threats.

Here are some ways in which scales serve as a defense mechanism for pangolins:

  • Armor: Pangolin scales are hard and overlapping, forming a protective armor that shields the animal from injuries and stress. When threatened, pangolins can roll up into a tight ball, presenting an unappetizing and impenetrable barrier of keratin scales to ward off predators. This defense mechanism is so effective that pangolins are not a significant prey species for any of the carnivores.
  • Camouflage: Pangolin scales are also useful for camouflage, as they blend in with the soil and vegetation in their natural habitat. This helps pangolins avoid detection by predators and other threats.
  • Chemical defense: Some species of pangolins can also release a stinky fluid from a gland at the base of their tails as a chemical defense mechanism. This fluid can deter predators and other threats, making it easier for the pangolin to escape.

The evolutionary advantages of having such protective armor are clear.

Pangolins are able to survive in environments where they are exposed to a variety of threats, including predators, injuries, and stress.

The armor also allows them to forage for food in the soil without getting injured.

The ability to roll up into a tight ball is a particularly effective defense mechanism, as it makes it difficult for predators to attack the vulnerable parts of the pangolin’s body.

Overall, the scales provide a crucial layer of protection that allows pangolins to survive in their natural habitats.

In summary, pangolin scales serve as a defense mechanism for these animals, providing protection against predators and other threats.

The armor, camouflage, and chemical defense mechanisms provided by the scales allow pangolins to survive in environments where they are exposed to a variety of threats.

Growth and Shedding of Scales

Pangolin scales grow throughout their lives, similar to hair, and the edges of the scales are constantly filed down as pangolins dig burrows and tunnel through the soil in search of termites and ants.

Pangolin scales are made of keratin, the same protein that forms human hair and fingernails

However, unlike reptiles, pangolins do not shed their scales as they grow. Instead, the scales remain attached to the pangolin’s skin throughout its life, forming a protective armor that shields the animal from injuries and stress.

Scale Variations among Pangolin Species

Pangolin scales vary in appearance among different species.

Here are some variations in scale patterns and characteristics among different pangolin species:

  • Asian pangolins: The four species of Asian pangolins have scales that are more rounded and smoother than those of African pangolins. They also have hair between their scales, which is absent in African pangolins.
  • African pangolins: The four species of African pangolins have scales that are more elongated and pointed than those of Asian pangolins. They also have bristles that emerge from between the scales, which are absent in Asian pangolins.

According to a study on pangolin genomes and the evolution of mammalian scales and immunity, there are genetic differences between pangolins and their closest relatives that may account for the unique characteristics of pangolin scales.

 However, there is limited research on the variations in scale patterns and characteristics among different pangolin species.

Scale Regeneration

After searching for information on whether pangolins have the ability to regenerate lost scales and the mechanisms involved in this process, I found limited research on this topic.

However, I found a study that investigated the water-assisted self-healing behavior of pangolin scales.

The study found that pangolin scales have a unique structure that allows them to recover from indentation damages, which imitate the injury of a predator attack

The study also found that the water-assisted self-healing behavior of pangolin scales is due to the presence of a network of micro channels that can transport water to the damaged area, facilitating the rehydration and reformation of the keratin fibers.

Human Threats to Pangolin Scales

The illegal trade and poaching of pangolins for their scales is a significant threat to the survival of these animals.

Pangolin scales are believed to have medicinal properties in some cultures, which has led to a high demand for them in traditional medicine markets in Asia and Africa

Here are some conservation efforts in place to protect pangolins from this threat:

  • International trade ban: All eight species of pangolin are protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which prohibits the commercial trade of pangolins and their parts. This is the highest level of international law and provides legal protection for pangolins.
  • Law enforcement: Law enforcement agencies around the world are working to crack down on the illegal trade and poaching of pangolins.

    This includes increasing patrols in pangolin habitats, conducting raids on illegal wildlife markets, and prosecuting poachers and traffickers.
  • Public awareness campaigns: Many organizations are working to raise public awareness about the plight of pangolins and the threats they face.

    This includes campaigns to educate people about the importance of pangolins in their ecosystems and the need to protect them from illegal trade and poaching.
  • Rehabilitation and release: Some organizations are working to rehabilitate pangolins that have been rescued from the illegal wildlife trade and release them back into the wild.

Despite these efforts, the illegal trade and poaching of pangolins for their scales continues to be a significant threat to their survival.

More needs to be done to address this issue and protect these unique and important animals.
