Invasive Spotted Lanternflies: A Threat to New Jersey’s Plants and Agriculture

What is a Spotted Lanternfly?

The spotted lanternfly is an invasive insect native to China, India, and Vietnam. It was first discovered in the United States in Berks County, Pennsylvania in 2014. Since then, it has spread to four states, including New Jersey.

Adult spotted lanternflies are about one inch long and have black bodies with colorful wings that are half-red and half-grey with black spots. They feed on over 70 species of plants, including maple, walnut, fruit trees, and grapevines.

Why is the Spotted Lanternfly a Threat?

Spotted lanternflies can cause significant damage to plants by piercing them with their mouthparts and sucking out the sap. They also excrete a sugary substance called honeydew, which can promote fungus growth and damage or kill plants.

How Does the Spotted Lanternfly Spread?

The spotted lanternfly is an excellent hitchhiker and has been known to travel on vehicles, luggage, and other objects. It can also fly short distances.

What Counties in New Jersey Are Quarantined?

Eight counties in New Jersey are under quarantine due to the spotted lanternfly infestation:

  • Bergen
  • Burlington
  • Camden
  • Essex
  • Hunterdon
  • Mercer
  • Middlesex
  • Monmouth

What Can You Do to Help?

Residents in affected areas can help to reduce the spread of spotted lanternflies by taking the following steps:

  • Check your vehicles and belongings for spotted lanternflies before traveling.
  • Report any sightings of spotted lanternflies to the New Jersey Department of Agriculture.
  • Scrape egg masses off of tree trunks and double-bag them before throwing them away.
  • Use sticky tape around trees to trap spotted lanternflies as they crawl up the trunks.
  • Kill spotted lanternflies on sight.

Spotted Lanternfly Life Cycle

Spotted lanternflies go through several life stages before reaching their adult form:

  • Early nymphs: Black with white spots, about an eighth of an inch long (April-July)
  • Late nymphs: Red and black with white spots, about half an inch long (July-September)
  • Adults: Black bodies with colorful wings, about one inch long (July-December)

Spotted Lanternfly Egg Masses

Spotted lanternflies lay eggs once a year, leaving egg masses that look like smeared modeling clay. These egg masses are often found on tree bark. If left unnoticed, they can hatch into swarms of spotted lanternflies in the spring.

Spotted Lanternfly and the Tree of Heaven

The spotted lanternfly has a strong preference for the tree of heaven, another invasive species from Asia. The tree of heaven is hard to control because of its vast root systems. To remove a tree of heaven, all of the roots must be removed, as even a small piece of root left behind can grow into a new tree.

Spotted Lanternfly Pest Management

The focus of spotted lanternfly pest management is on controlling the tree of heaven, as the insect may rely on this tree for reproduction. Other pest management strategies include:

  • Killing spotted lanternflies on sight
  • Removing egg masses from trees
  • Using sticky tape to trap spotted lanternflies
  • Applying insecticides to infested areas

Conclusion

The spotted lanternfly is a serious threat to New Jersey’s plants and agriculture. By taking the steps outlined in this article, residents can help to reduce the spread of this invasive pest.

Toadzilla: The Astonishing Discovery of Australia’s Largest Toad

by Rosa
written by Rosa

Toadzilla: The Largest Toad Ever Found in Australia

Discovery and Size

In the vast Conway National Park in Queensland, Australia, park rangers stumbled upon an extraordinary sight: a colossal cane toad that weighed an astonishing 5.95 pounds. Dubbed “Toadzilla,” this behemoth shattered the previous Guinness World Record for the heaviest toad, which stood at 5.81 pounds.

Toadzilla’s Characteristics

Toadzilla’s massive size was not its only distinguishing feature. Female cane toads tend to be larger than males, and Toadzilla’s size suggested that it was indeed a female. The typical cane toad weighs around three pounds and measures four to six inches in length, but Toadzilla dwarfed its counterparts.

Ecological Impact of Cane Toads

Cane toads are native to Central and South America, but they were introduced to Australia in 1935 as a misguided attempt to control cane beetles. However, this introduction had disastrous consequences. Cane toads have no natural predators or diseases in Australia, and they have multiplied rapidly, becoming an invasive species.

Toadzilla’s size and reproductive capacity made it a particular threat to the Australian ecosystem. Female cane toads can lay up to 35,000 eggs at a time, and all parts of their breeding cycle are poisonous to native Australian species. Toadzilla’s presence in the park posed a significant risk to local wildlife.

Management and Euthanasia

Due to the potential damage Toadzilla could cause to the environment, the Queensland Department of Environment and Science made the difficult decision to euthanize it. Euthanasia is a humane method of ending an animal’s life when necessary for reasons such as controlling invasive species or preventing harm to native ecosystems.

Scientific Study

Toadzilla’s body was sent to the Queensland Museum for further study. Scientists hope to gain insights into the toad’s biology, reproductive capacity, and the factors that contributed to its extraordinary size.

Preventing Cane Toad Spread

Cane toads are a major threat to Australia’s biodiversity. They have no natural predators, they can reproduce rapidly, and their poison is deadly to native species. Preventing the spread of cane toads is essential for protecting the Australian ecosystem.

What You Can Do

  • Avoid transporting cane toads to new areas.
  • Report any sightings of cane toads to your local authorities.
  • Support research and conservation efforts to control cane toad populations.

Toadzilla’s Legacy

Toadzilla’s discovery has highlighted the devastating impact that invasive species can have on fragile ecosystems. It serves as a reminder of the importance of responsible environmental management and the need to protect our native wildlife.

Sea Lampreys: A Persistent Threat to the Great Lakes

Invasive Bloodsuckers

Sea lampreys, parasitic fish native to the Atlantic Ocean, have become a major threat to the Great Lakes ecosystem. They were first introduced to the lakes in the 1800s through shipping canals and have since spread throughout the entire system.

Destructive Impacts

Sea lampreys attach to fish using their suction cup mouths and rasp away at their flesh with their sharp tongues, feeding on their blood and body fluids. A single sea lamprey can kill up to 40 pounds of fish per year. Their voracious feeding habits have devastated fish populations in the Great Lakes, particularly trout and whitefish.

Population Control Challenges

Since 1958, the Great Lakes Fishery Commission has implemented a dedicated control program to combat the sea lamprey population. Lampricide, a pesticide specifically designed to target sea lamprey larvae, has been used along with traps and barriers to reduce their numbers. These efforts have successfully reduced the sea lamprey population by 90-95% in the Great Lakes basin.

Covid-19 Disruption

Travel restrictions during the Covid-19 pandemic hindered the application of lampricide and other control measures, leading to a resurgence in the sea lamprey population. This increase became evident in 2022 due to the two-year lag in the animals’ spawning cycle.

Ongoing Control Efforts

Despite the challenges posed by Covid-19, the Great Lakes Fishery Commission has resumed its aggressive control program in 2022 and 2023. They are hopeful that the recent population spike was a temporary blip and that the control measures will continue to keep the sea lamprey population in check.

Ecological Role in Native Range

In their native Atlantic Ocean habitat, sea lampreys play a beneficial role as keystone species and ecosystem engineers. They support both aquatic and terrestrial ecosystems by providing food for other creatures and creating spawning habitats for fish. Their larvae also help maintain water quality.

Evolutionary Resilience

Sea lampreys have existed on Earth for over 340 million years and have survived four major extinction events. They have remained largely unchanged since they evolved, demonstrating their remarkable evolutionary resilience.

Historical Spread in the Great Lakes

Sea lampreys were first documented in the Great Lakes in 1835 in Lake Ontario. Niagara Falls initially served as a natural barrier to their spread, but improvements to the Welland Canal in 1938 allowed them to bypass the falls and invade the entire system. By the 1960s, sea lampreys had devastated the upper Great Lakes’ trout fishery, reducing the take of lake trout from 15 million pounds to just half a million pounds.

Economic Impacts

The decline in fish populations due to sea lampreys has had a significant economic impact on the Great Lakes fishing industry. The rebuilding of the fishery through control efforts has led to a resurgence in the fishing economy, benefiting both commercial and recreational fishers.

Continuing Vigilance

While the Great Lakes Fishery Commission has made significant progress in controlling the sea lamprey population, continued vigilance is necessary to prevent future outbreaks. The commission is committed to monitoring the population and implementing adaptive control measures as needed to protect the Great Lakes ecosystem and its valuable fisheries.

Florida’s Ongoing Battle with Stealthy Pythons: Impacts and Challenges

by Rosa
written by Rosa

Florida’s Ongoing Battle with Invasive Pythons

Introduction

Florida has a long history of grappling with invasive species, including the infamous Burmese python. These non-native predators have established a thriving population in the Everglades ecosystem, posing significant threats to native wildlife and the environment.

Stealthy Predators

Pythons are renowned for their exceptional stealth capabilities. Their ability to blend seamlessly into their surroundings makes them difficult to detect and capture. Researchers have observed pythons remaining undetected even when standing mere feet away from them, despite being equipped with radio transmitters.

Internal GPS

In a recent study, scientists discovered that pythons possess an internal GPS-like mechanism that allows them to navigate back to their original capture locations with remarkable accuracy. This ability further complicates efforts to control their population through relocation.

Failed Control Measures

Last year, Florida implemented a python hunting challenge to reduce the population of these invasive snakes. However, the challenge yielded disappointing results, with hunters capturing only a small fraction of the estimated 100,000 pythons residing in the Everglades.

Ecological Impacts

The presence of pythons in the Everglades has had a profound impact on the ecosystem. They compete with native predators for food and prey, leading to population declines in species such as deer, rabbits, and birds. Additionally, pythons have been implicated in the spread of diseases and parasites.

Challenges in Extermination and Relocation

Given their stealthy nature and ability to return to their home range, exterminating or relocating pythons has proven to be an extremely difficult task. Traditional control methods, such as hunting and trapping, have yielded limited success.

Potential Solutions

Researchers and wildlife managers are actively exploring various approaches to manage the python population, including:

  • Developing more effective hunting and trapping techniques
  • Utilizing advanced technologies for detection and tracking
  • Identifying ways to disrupt python navigation abilities
  • Investigating biological control methods, such as the introduction of natural predators

Florida’s New Pest

Despite these ongoing efforts, it appears that Florida will have to learn to coexist with pythons as a permanent resident of the Everglades ecosystem. The challenges posed by these invasive predators require innovative solutions and continued research to minimize their ecological impacts.

Giant Mice of Gough Island: A Case of Island Evolution and Conservation Crisis

by Rosa
written by Rosa

Giant Mice of Gough Island: A Case of Island Evolution

Nestled in the remote South Atlantic, Gough Island is a haven for seabirds. However, this avian paradise has been invaded by an unlikely predator: giant mice. These mice, descendants of rodents that arrived on the island in the 19th century, have evolved to be twice as large as their mainland counterparts. Their unusual size and predatory behavior are threatening the survival of several seabird species on the island.

Evolutionary Adaptation

Researchers have discovered that the mice on Gough Island have adapted to their unique environment through a process called island gigantism. This phenomenon occurs when small animals introduced to an island without natural predators or competition grow larger over time. On Gough Island, the mice have found an abundant food source in the form of seabird chicks. This steady diet of high-calorie prey has allowed them to maintain their body mass or even gain weight during winter, when food is scarce.

Ecological Impact

The mice’s predation on seabird chicks has had a devastating impact on the island’s avian populations. Two critically endangered species, the Tristan albatross and the Gough bunting, are facing extinction due to the mice’s voracious appetite. The mice are also contributing to declines in other seabird species, threatening the entire island ecosystem.

Conservation Challenges

Researchers are actively studying ways to control the mice population on Gough Island. One potential solution is an aerial drop of poison bait pellets. However, this operation would be complex, costly, and risky. There is no guarantee of success, but researchers believe that it is the only way to save the island’s seabirds from extinction.

The Role of Diet

The mice on Gough Island provide a unique example of how diet can influence evolution. Their unusually large size is a direct result of their adaptation to a diet of seabird chicks. This research highlights the importance of understanding the complex interactions between species and their environment.

Island Ecology

The case of the giant mice on Gough Island is a fascinating example of island ecology. Islands provide unique environments that can lead to the evolution of distinct species and populations. Understanding the ecological processes that occur on islands can help us better manage and conserve these fragile ecosystems.

Invasive Species

The mice on Gough Island are an example of an invasive species, a non-native species that has been introduced to an ecosystem and causes harm to native species. Invasive species can have a significant impact on biodiversity and ecosystem functioning. Preventing the introduction of invasive species and managing existing populations are crucial for the conservation of island ecosystems and the species that depend on them.

Fall Armyworms: An Unprecedented Invasion Devastating Lawns and Crops

by Rosa
written by Rosa

Fall Armyworms: An Unprecedented Invasion

Introduction

Fall armyworms, an invasive species of caterpillar, are wreaking havoc on lawns and crops across the United States at an unprecedented scale. These voracious pests can turn lush green grass brown in a matter of hours, leaving behind a trail of devastation.

Biology and Behavior

Fall armyworms are the larvae of moths that can travel hundreds of miles in a single day. They lay their eggs on leaves, grass, and other vegetation, and the eggs hatch into caterpillars within a week. The caterpillars have a distinctive Y-shaped head and three stripes running down their bodies.

Impact on Lawns and Crops

Once hatched, fall armyworms feed on the roots and leaves of plants, causing rapid damage and nutrient depletion. Lawns can be turned brown in less than 48 hours, while crops can suffer severe yield losses.

Factors Contributing to the Infestation

This year’s fall armyworm infestation is particularly severe due to several factors, including:

  • Favorable weather patterns that have allowed moths to disperse widely and lay eggs in new areas
  • Large populations of fall armyworms in previous years
  • Reduced natural predators due to pesticide use
  • Susceptibility of certain grass species to fall armyworm damage

Management and Control

Insecticides are the most effective method for controlling fall armyworms. However, they must be applied quickly to prevent significant damage. Reseed only after the threat of a second wave of hatchlings has passed.

Managing Expectations

Even with proper management, it is important to note that fall armyworms can be difficult to control completely. Focus on managing populations and minimizing damage rather than eliminating them entirely.

Long-Term Strategies

To reduce the impact of fall armyworms in the long term, consider the following strategies:

  • Plant resistant grass species
  • Encourage natural predators, such as birds and parasitic wasps
  • Use cultural practices, such as crop rotation and proper irrigation, to make the environment less favorable for fall armyworms

Additional Information

  • Fall armyworms are native to the Americas but have spread to other parts of the world, including Africa and Asia.
  • The caterpillars can feed on over 80 different plant species, including corn, soybeans, and cotton.
  • In severe infestations, fall armyworms can cause millions of dollars in damage to crops.

Call to Action

If you suspect that your lawn or crops are being affected by fall armyworms, contact your local agricultural extension office for assistance. Early detection and management are crucial to minimize damage and protect your valuable plants.

The Giant African Snail: A Nightmare for Australia and Beyond

The Invasive Threat

The giant African snail (GAS) is a formidable invasive species that has plagued Australia and other regions worldwide. These colossal mollusks, capable of reaching the size of a baseball, pose a significant threat to agriculture, human health, and the environment.

Size and Reproductive Capacity

GAS are known for their enormous size and astonishing reproductive capacity. They can lay up to 1,200 eggs per year, making population control extremely challenging. This prolific breeding rate contributes to their rapid spread and establishment in new territories.

Extreme Adaptability

GAS possess an impressive ability to adapt to diverse environmental conditions. They can withstand extreme temperatures, from freezing to scorching, and have no natural predators in many regions where they have become invasive. This adaptability allows them to thrive in a wide range of habitats.

Crop Destruction and Economic Impact

GAS voraciously consume over 500 species of plants, including staple crops such as citrus, vegetables, and grains. Their feeding habits can cause severe economic losses for farmers and agricultural industries. In Florida, the estimated annual cost of GAS damage exceeded $11 million during previous infestations.

Human Health Risks

Beyond their agricultural impact, GAS also pose a health risk to humans. They carry a parasitic nematode that can cause meningitis, a potentially fatal infection. Contact with GAS or their secretions can transmit this parasite, highlighting the importance of proper handling and control measures.

Australia’s Battle Against GAS

Australia has a long history of battling GAS infestations. In 1977, a major outbreak in Brisbane resulted in an eight-month eradication campaign that exterminated over 300 snails. In recent years, GAS have resurfaced in Australia, prompting swift action from officials to prevent further spread.

Global Spread and Control Efforts

GAS originated in East Africa but have now established populations on numerous Pacific and Indian Ocean islands, as well as in other regions. The global distribution of GAS highlights the need for coordinated control efforts and strict quarantine measures to prevent their introduction and establishment in new areas.

Historical Outbreaks and Lessons Learned

Miami, Florida, has also experienced multiple GAS outbreaks. In 1975, the city spent over $1 million to eradicate an infestation, while a more recent outbreak in 2011 involved the discovery of over 1,100 snails within a one-square-mile area. These incidents underscore the importance of early detection and rapid response to prevent the spread of this invasive pest.

Ongoing Research and Management Strategies

Scientists and researchers continue to study GAS, seeking a deeper understanding of their biology, behavior, and potential control methods. Integrated pest management strategies, including habitat modification, chemical treatments, and biological control, are employed to combat GAS infestations.

Public Awareness and Education

Public awareness and education play a crucial role in preventing the spread of GAS. Educating communities about the risks associated with GAS, proper handling techniques, and reporting procedures can help mitigate the impact of future infestations.

Conclusion

The giant African snail remains a formidable invasive threat, posing risks to agriculture, human health, and the environment. Ongoing efforts to control and eradicate GAS infestations require a multi-faceted approach involving research, management strategies, and public engagement. Early detection, rapid response, and international collaboration are essential to minimize the impacts of this invasive species.

Black Widow Spiders Under Attack: The Rise of the Brown Widow

Black Widow Spiders: The Not-So-Deadly Predators

Black widow spiders, known for their iconic red hourglass markings and potent venom, have long captured the public’s imagination. However, despite their fearsome reputation, these arachnids are actually relatively shy creatures that primarily feed on insects and other small animals. Human fatalities from black widow bites are rare, and victims can be treated with antivenom if necessary.

The Invasion of the Brown Widow

In recent years, black widow spiders have faced a new threat: the invasive brown widow spider. Originating from Africa or South America, brown widows have colonized every continent except Antarctica. They were first detected in the United States in 1935 and have since spread across the South and parts of the West.

Predation and Competition: A Deadly Rivalry

Brown widow spiders are highly aggressive towards black widows, actively seeking them out and attacking them. This predatory behavior has led to a decline in black widow populations in areas where brown widows have become established.

Researchers have observed that brown widows are particularly aggressive towards young black widows, killing and eating them 80% of the time. In pairings of adults, black widows were eaten in 40% of trials, while they defensively killed brown widows 30% of the time.

In addition to predation, brown widows may also be outcompeting black widows for resources such as food and habitat. Brown widows can lay more eggs and reproduce earlier in their lives than black widows, giving them a reproductive advantage.

Unveiling the Behavioral Differences

The reasons for the stark behavioral differences between brown widow and black widow spiders are not fully understood. However, researchers speculate that it may be related to their distinct evolutionary histories and ecological niches.

Brown widows are known for their bold and aggressive behavior, while black widows are more shy and defensive. This difference in temperament may influence their interactions with each other and with other species in their environment.

Ecological Implications: The Impact of Invasive Species

The invasion of brown widow spiders has significant ecological implications. The decline of black widow populations could disrupt insect populations and alter predator-prey relationships within ecosystems.

Furthermore, brown widows may also pose a threat to other native spider species, as they have been observed displacing them through predation and competition.

Future Research and Management Strategies

Researchers are continuing to study the interactions between brown widow and black widow spiders in different parts of the world. They hope to gain a better understanding of the factors driving black widow population declines and the potential impact of brown widows on native ecosystems.

Based on their findings, scientists may develop management strategies to mitigate the negative effects of brown widow invasion and protect native spider populations.

Arctic Shipping: A Gateway for Invasive Species and Threats to Marine Ecosystems

by Peter
written by Peter

Arctic Shipping: A Gateway for Invasive Species

Impact on Marine Ecosystems

As Arctic sea ice melts due to climate change, new shipping routes are opening up, connecting the Atlantic and Pacific Oceans. While this presents opportunities for faster and more efficient shipping, it also raises concerns about the spread of invasive species.

Invasive species are organisms that are introduced to a new environment and cause ecological or economic harm. They can disrupt local ecosystems, outcompete native species, and damage infrastructure. Shipping is a major pathway for the introduction of invasive species, as vessels can carry organisms in their ballast water or attached to their hulls.

Arctic waters have historically had low exposure to invasions, but as shipping traffic increases, so does the risk of introducing invasive species. These species could threaten the Arctic’s fragile ecosystems, which are already facing the impacts of climate change.

Risks to American Ports

Invasive species can also pose a threat to the United States economy. American ports handle a significant amount of global cargo, and any disruption to port operations could have far-reaching consequences. Invasive species can damage infrastructure, such as pipes and boats, and cause economic losses by competing with native species for resources.

Climate Change and Invasive Species Spread

The melting of Arctic sea ice is not only opening up new shipping routes but also exposing new areas for resource exploitation. This could further increase the risk of invasive species spread, as ships and equipment can transport organisms from one region to another.

Mitigation Strategies

There are several strategies that can be implemented to minimize the spread of invasive species through Arctic shipping. One is the wider adoption of open water ballast exchange, which involves replacing coastal ballast water with water from the open ocean. Invasive species are less likely to survive in deep-water ecosystems.

Another strategy is to establish standards for the amount of organisms that ships can discharge in their ballast water. Currently, no such standards exist, but they could help to prevent the introduction of invasive species.

Hull maintenance is also important, as it can help to prevent organisms from attaching to ships’ hulls and being transported to new areas.

Future Implications

As the Arctic continues to open up, it is crucial to consider the potential impacts of invasive species. By taking proactive steps to mitigate the risks, we can protect both Arctic ecosystems and the global economy.

Additional Considerations

In addition to the strategies mentioned above, other considerations for minimizing invasive species spread include:

  • Investing in research on the potential impacts of invasive species in the Arctic
  • Educating shipping companies and crew members about the risks of invasive species
  • Developing and implementing international agreements to prevent the spread of invasive species
  • Establishing monitoring programs to track and respond to invasive species introductions

by Rosa
written by Rosa

Discovery of 24 New Caribbean Skinks: Half Facing Extinction

Groundbreaking Discovery

In a remarkable scientific breakthrough, biologists have announced the discovery of 24 new species of lizards known as skinks in the Caribbean islands. This major discovery, led by renowned herpetologist Blair Hedges of Penn State University, has significantly expanded our understanding of the region’s biodiversity.

Taxonomic Triumph

Using a combination of traditional taxonomy and advanced DNA analysis, Hedges and his team meticulously examined skink specimens from zoos and conservation centers worldwide. Their research revealed a total of 39 distinct species of skinks inhabiting the Caribbean, including six previously recognized species, nine that had been historically named but later deemed invalid, and the 24 entirely new species.

Evolutionary Journey

Evidence suggests that the Caribbean skinks originated in Africa approximately 18 million years ago, likely arriving on floating rafts of vegetation. Over time, they diversified into a remarkable array of species, each adapted to its unique ecological niche.

Conservation Crisis

Despite their long evolutionary history, the Caribbean skinks now face a dire conservation crisis. The researchers determined that half of the newly discovered species are critically endangered, with some potentially already extinct in the wild. The primary threat to these lizards is the invasive mongoose, introduced to the Caribbean in the 19th century to control rodent populations. The mongoose has decimated skink populations, and ongoing human activities such as forest removal further exacerbate their vulnerability.

Urgent Conservation Imperative

The discovery of these new skink species highlights the urgent need for conservation efforts. The research team emphasizes the importance of protecting their remaining habitats, implementing mongoose control measures, and raising awareness about the plight of these endangered reptiles.

Distribution and Habitat

The newly discovered skink species exhibit a diverse range of distributions and habitat preferences. Some species are found on multiple islands, while others are restricted to a single island or even a specific region of an island. Their habitats vary from coastal dunes to lush rainforests, reflecting their remarkable adaptability.

Morphological Distinctions

The skink species can be distinguished from one another based on various morphological characteristics, including scale shape, body size, and coloration. DNA analysis has also played a crucial role in identifying and confirming the distinct genetic lineages of these lizards.

The Importance of DNA Analysis

DNA analysis has proven invaluable in identifying new species of skinks, particularly those that exhibit subtle morphological differences. By comparing genetic data, scientists can determine the evolutionary relationships between species and identify even closely related species that may have been overlooked in the past.

Conservation Challenges

Conserving the newly discovered Caribbean skinks poses significant challenges. Their rarity, coupled with the ongoing threats from invasive species and habitat loss, makes it imperative to implement comprehensive conservation measures. Researchers are working with local communities and conservation organizations to develop and implement effective strategies to protect these unique and endangered lizards.

Tips for Skink Observation

If you are fortunate enough to visit the Caribbean islands, you may be able to spot one of these elusive skinks. However, due to their rarity, it is essential to exercise patience and respect their fragile existence. Remember to observe them from a distance and avoid disturbing their natural behavior.
