Can Axolotl Go on Land? (No, Here’s Why…)

Can Axolotl Go on Land? (No, Here’s Why…)


Axolotls (Ambystoma mexicanum) are amphibians that remain in their larval form throughout their lives. They are native to the Xochimilco Lake complex near Mexico City and are adapted to living in water.

Axolotls have gills for breathing underwater and cannot live on land.

Their bodies are not designed for a terrestrial environment as they lack strong limbs and efficient lungs for breathing air. Therefore, Axolotls can only survive in water and cannot live on land for long periods.

This text explains why Axolotls are strictly aquatic and the dangers they face if removed from their water habitat.

Axolotl Anatomy Overview

Axolotls possess a distinct anatomy with external gills and a permanent aquatic larval form, lacking developed features for land movement. This confines them to water environments.

They exhibit neoteny, retaining juvenile characteristics their entire lives, unlike other amphibians which metamorphose and adapt to land.

Axolotls use their external gills, which extend from behind their heads, for respiration. These gills have a large surface area for oxygen exchange and are well-supplied with blood vessels.

Although Axolotls also have simple lungs, they primarily breathe through their gills and only use their lungs to gulp air occasionally when water oxygen levels are low.

Their limbs are adapted for water navigation, not for walking on land, and their skeletal structure isn’t strong enough to support their weight outside of water. Their thin, permeable skin is designed for water balance but is prone to drying out on land.

Understanding Axolotl Respiration

Axolotls primarily use their external gills to breathe underwater and are not designed for long periods on land. They extract oxygen from the water through their gills, which are rich in blood vessels, enabling efficient oxygen and carbon dioxide exchange with the water.

These amphibians retain their gills for life due to their neotenic state, where they mature sexually without transforming into a terrestrial form like other amphibians. They do have lungs, but these are basic and not effective for breathing air.

Axolotls can only survive briefly out of water, for about an hour, and it’s not advisable to put them in such situations. Being out of water can cause breathing difficulties and other health problems.

Their limbs are unsuitable for walking on land, making movement difficult and potentially injurious.

Axolotls risk dehydration and drying out of their protective mucus coating when out of water, which is vital for breathing and overall health. The loss of this layer impairs oxygen absorption and increases disease susceptibility.

Therefore, Axolotls’ breathing is closely linked to their aquatic habitat, and removing them from it can be dangerous.

The Aquatic Nature of Axolotls

Axolotls are aquatic animals that reside exclusively in water. They possess adaptations that prevent them from living on land.

These adaptations include external gills that allow them to extract oxygen from water efficiently. Although they can breathe air, this is only a short-term solution.

Their body structure is also suited for life in water. Axolotls have limbs that cannot support their weight on land, and their skin needs constant contact with water to stay hydrated.

If they spend too much time out of water, they can suffer from health problems, including dehydration and organ damage.

Axolotls exhibit neoteny, meaning they retain their larval features throughout their lives and don’t metamorphose into a land-dwelling form like other amphibians.

This evolutionary trait necessitates a permanent aquatic habitat for their survival. Therefore, Axolotls aren’t adapted for terrestrial living.

Land Mobility in Axolotls

Axolotls have limited ability to move on land due to their skeletal and muscular structures being adapted for water. Their bodies aren’t designed to support their weight outside of water, making land movement inefficient and potentially harmful. This highlights the need for an aquatic habitat for their well-being.

Limb Functionality Ashore

Axolotls have limbs that are not designed for walking on land. Their body structure is made for living in water, which involves swimming rather than moving on solid ground.

Their limbs are soft and similar to fins, which helps them move in water but not on land. The muscles and bones of Axolotls are meant to support them in water, where they are buoyant, rather than on land where they would have to resist gravity.

Although Axolotls cannot move effectively on land, they can regenerate lost limbs while in their aquatic habitat. This regeneration is a separate aspect of their adaptability and isn’t connected to their land mobility.

Terrestrial Survival Limitations

Axolotls lack the necessary adaptations for living on land and cannot move well or support their body weight outside of water. They retain their aquatic features throughout their lives and don’t develop lungs for breathing air.

Moreover, Axolotls rely on their gills for oxygen. Being on land can lead to dehydration and breathing difficulties, which can be fatal if they are not returned to water quickly.

Risks of Terrestrial Exposure

Axolotls are amphibians that require an aquatic environment to stay healthy. Being on land can harm their health due to their dependence on water for bodily functions.

Here are the main health risks for Axolotls when exposed to terrestrial conditions:

  • Dehydration and Organ Damage: Axolotls need their moist slime coat for water and salt balance. On land, the slime coat dries, leading to dehydration and potentially causing kidney failure and damage to other organs.
  • Oxygen Absorption and Respiratory Distress: Axolotls have gills to breathe underwater. They can’t absorb oxygen effectively on land, which may cause breathing problems.
  • Physical Stress and Behavioral Changes: Axolotls are not built to walk on land; doing so can cause stress and injury. This stress may lead to behavior changes such as hiding or eating less, weakening their immune system.
  • Increased Susceptibility to Diseases: Axolotls are more prone to infections and diseases without their slime coat, as the coat acts as a barrier to pathogens.

Axolotl Skin Sensitivity

Axolotl skin is very sensitive since it is permeable and needs to stay in the water to keep its protective mucus layer. This layer helps with water balance, protects against disease, and allows them to breathe.

Axolotls’ sensitivity comes from their neoteny, which means they keep their young age features, like gills, throughout their lives and must live underwater.

They don’t go through metamorphosis like other amphibians to develop tough skin for life on land. Axolotls can become dehydrated, struggle to breathe, and become more prone to infections and diseases when they are out of water and without their mucus.

Water quality and temperature are also important for Axolotls. Sudden changes can stress them and damage their skin, increasing disease risk. It’s crucial to keep their water clean and stable.

Water Dependency Explained

Axolotls require a watery habitat to survive. Their bodies are adapted for living in water, which supports their breathing through gills.

Axolotls aren’t well-adapted for land, as their limbs are not suited for walking and they cannot breathe air effectively. They must stay submerged to maintain their health.

Aquatic Habitat Necessity

Axolotls are amphibians that must live in water due to their evolutionary development of neoteny, which means they keep their juvenile features, such as gills for breathing underwater, throughout their lives.

The main reasons why Axolotls need an aquatic environment are mentioned below:

  • Physiological reliance: Axolotls need water to breathe and to maintain their mucus layer, which is crucial for oxygen absorption and preventing illness.
  • Morphological design: Their bodies are shaped for swimming, and their limbs are made for moving in water, not for walking on land.

Removing axolotls from water can cause serious health problems, underlining the importance of their aquatic lifestyle.

Terrestrial Mobility Limitations

Axolotls are not capable of moving effectively on land due to their body structure, which is designed for life in water. Their limbs are too weak to support their weight on land, and their gills are not efficient at extracting oxygen from the air, making it difficult for them to breathe outside of water.

Being on land for too long can cause Axolotls to become dehydrated and more susceptible to stress and illness.

Therefore, they rely on an aquatic environment to survive and stay healthy. Water is essential for their life cycle.

Gill Functionality Constraints

Axolotls have gills that are designed to work underwater, which makes it difficult for them to breathe on land.

The gills, which look like feathers, need water to stay open and functional. Out of the water, the gills collapse, and the Axolotl cannot breathe properly.

Axolotls need water to breathe due to their specialized gills, which is why they are aquatic and rarely found on land.

Handling Axolotls Safely

When handling Axolotls, it’s vital to keep their exposure to air brief because they are aquatic animals and can become stressed on land.

To move an Axolotl, use a soft net to protect its skin and gills. Avoid touching the Axolotl with bare hands to prevent transferring oils or other substances that could harm it. Instead, handle with wet hands or wet gloves if necessary.

Quickly place the Axolotl to water, maintaining clean conditions with proper temperature and pH.

Minimizing handling will help the axolotl stay healthy and reduce stress.

Potential for Axolotl Metamorphosis

Axolotl metamorphosis is rare and involves both hormonal and environmental influences.

The hormone thyroxine is critical for starting the change from living in water to living on land.

Environmental factors, like lower water levels or higher temperatures, can also cause this adaptation.

Hormonal Influence

Hormonal changes, particularly an increase in thyroxine, can cause a rare transformation in some Axolotls, leading them to develop features needed for life on land. This change is different from their typical neoteny, where they keep their young age traits into adulthood.

The hormonal influence changes their physical form:

  • Neoteny: Axolotls normally show neoteny, reaching sexual maturity without metamorphosis. They keep their aquatic features, such as external gills, as adults.
  • Hormonal Influence on Metamorphosis: A higher level of thyroxine initiates the metamorphosis. This can lead to the loss of gills and the formation of lungs, which allows for terrestrial living, although this is uncommon and usually not sustainable for the species.

Environmental Triggers

Environmental triggers can cause Axolotls to undergo metamorphosis, which is a transition from an aquatic to a terrestrial lifestyle.

Axolotls usually exhibit neoteny, maintaining young age characteristics like gills throughout their lives. However, environmental factors such as changes in water temperature, hormonal fluctuations, or poor conditions in their habitat can initiate a rare metamorphosis.

This change allows them to develop lungs for air-breathing and other features for living on land.

Metamorphosis in Axolotls is rare and can cause stress and health issues. It’s generally advised against trying to induce this process because of potential risks.

Environmental Stress Factors

Axolotls, when taken out of water, face stress factors that can harm their health. They can breathe air through their gills but cannot live on land for long. Being removed from water can lead to serious issues.

In water, Axolotls are supported and can breathe easily. On land, they face problems like:

Physical Stress

  • Dehydration: Their skin needs to stay moist, and dry air causes them to lose water quickly.
  • Weight-bearing: Their limbs are not made to hold their weight on land, leading to stress.

Physiological Stress

  • Breathing Difficulty: They can’t breathe as effectively on land as they do in water.
  • Skin Damage: Their skin’s protective mucus is damaged on land, increasing infection risks.

Putting Axolotls on land, even for a short time, is harmful. They can only survive on land under special conditions, such as in a moist area. However, this is unnatural and not recommended.

Axolotls require environments similar to their natural aquatic habitats to maintain their well-being and avoid the stress of being on land.

Conservation and Habitat Preservation

Axolotls are fully aquatic amphibians that rely on clean water for survival. They once thrived in Lake Chalco and Lake Xochimilco near Mexico City, but urbanization and pollution have significantly reduced their habitat, endangering their existence.

Conservation efforts in Mexico City are crucial for the Axolotls’ survival, involving the cleanup and restoration of waterways, pollution control, and the reintroduction of native plants to provide shelter and food. Removing invasive fish that harm Axolotl populations is also part of these efforts.

Axolotl is recognized as a critically endangered species, prioritizing its conservation. This involves habitat restoration, public education about their importance and threats, and legal protections against activities damaging their environment.

Courtney Bailey and others advocate for Axolotls, promoting awareness of their value and contributing to conservation through education on care and knowledge of rare Axolotl morphs. Public engagement is key to gaining support for preservation efforts, helping to secure the Axolotl’s future.
