Can an Axolotl Regrow its Head?

How Many Ghost Shrimp In A 10 Gallon Tank

Axolotls, also known as the Ambystoma mexicanum, can regenerate their body parts through the brain. The brain plays a significant role in controlling the regeneration process through the nervous system, i.e., the brain and nervous system work together in the regeneration process.

Axolotls can not regrow its head because the brain detects damaged parts of axolotls’ bodies. Cutting out the axolotl’s head will hinder the brain’s operations when there is no life in the head. Regeneration will only happen when the axolotls are still alive, i.e., when the head is in perfect condition.


Can An Axolotls Regrow Its Head?

No, The head is a significant part of the body. Axolotls are known for regenerating certain parts of their body that will only happen with their head in position. Axolotls can only regenerate their body part when they are alive. 


Axolotls can not regrow their head because the brain plays a central role in contacting the nervous system in the regeneration process. If Axolotols lose their head, the brain will not be able to communicate with the nervous system, which will hinder the regeneration process. 


Axolotls can regrow some of their body parts except their head. Axolotls can regrow their eyes, spinal cord, ovaries, lungs, testes, backbone, muscles, and part of their brain.


 Once the axolotls lose their head where the brain is found, it is impossible to regrow any part of the body. The head is not part of what axolotls are to regenerate. Certain animals can regenerate their head, but the axolotls are limited to specific body parts.


Can Axolotls Regenerate The Brain?

According to research, Adult axolotls can regenerate the brain even if a large part is removed or damaged from the brain. Axolotls have limited capabilities to rebuild the original tissue structure.

Axolotls can regenerate part of their brain when it is damaged. However, the total damage to the brain does not have a solution for now, as only part of the brain can be renewed.


Axolotls can regenerate the front part of their brain. Losing part of their telencephalon can be regenerated, and the brain begins to build new neurons and structures. Axolotls can sense the damaged neurons and regenerate them.


Can Axotols regenerate their Limb?

Yes, an axolotl can regrow its limb. Axolotls are cannibals. Putting them together in the same tank could make them feed on each other’s limbs when hungry. However, they can still regrow their limb.  The brain detects the damage and regrows the limb with the help of the nervous system. Axolotls shed little blood after the limb is eaten.


Cells then move to the eaten limb to form blastema ( cells capable of regeneration). The formed blastema then regenerates the bone, muscle, and tissue. The limb forms and gradually grows to the perfect size.


Can Axolotls Regrow Their Heart?

No, axolotls can not regrow their heart. The heart is essential in the body and pumps blood equally to the body. Axolotls can regenerate things like the heart muscle and tissue.


Axolotls have three chambers of the heart. The Ventricle part of the heart can be damaged. This part of the heart can grow back and regenerate. The ventricle pumps blood and supplies blood to the body.


Why Can Axolotl Regenerate?

Axolotls genes can convert wound cells into stem cells, which is why they can regenerate. 


Not every animal and human has a stem cell. When they wound, skin cells cover the wound, but they cannot recover because of the absence of stem cells. 


 Axolotls blastema develops from the stem cell, which is why regrowth occurs. 

The brain sends a message to the blastema cells, instructing them to form tissue or organ similar to a missing organ.


How Long Does It Take For An Axolotls To Regenerate?


Axolotls’ regeneration depends solely on their age. Juvenile axolotls have a higher chance of regenerating their organs quickly than adult axolotls. The power to regenerate reduces as they grow.


Axolotls regenerate their limb between the range of 40 to 50 days. An axolotl’s third heart (ventricle ) is damaged. It takes 30 to 60 days to regenerate. The spinal cord that connects the tail takes 18- 24 days to restore.  Regeneration does not happen immediately, and it takes time. Regeneration depends on how severe the axolotls injury is and where the injury occurred.


An axolotl’s leg can regenerate five times. If the regeneration reoccurs consistently in a certain body part, it takes more time, and the axolotls will not be able to regrow the organ the same way. Numerous regeneration makes the system fail to change epithelial cells into stem cells.


As Axolotls age, their skin begins to get thick and lose its flexibility making it difficult to form a wound epithelium and increasing the chances of forming a complete limb structure. The axolotl’s hormone plays a role in the timing of regeneration in aging animals; the researchers have not verified this statement.


 However, if your axolotls take too long to regenerate part of your body, it is best to consult the veteran for help. The veteran will detect where the problem is and treat your pet accordingly.


Are Axolotls Prone To Pain?

Axolotls experience pain, but they don’t feel pain except in their head or on their head.


What Happens If you cut your Axolotls Into Half?

Axolotls will lose their life when you split them into half because their internal dissection is asymmetrical. Axolotl’s ability to regenerate their body part is surprising.  It’s best to avoid splitting your axolotls, thinking it will regenerate, which is impossible.


What Other Animals Can Regrow Their Body Parts Apart From Axolotls?

Do not be surprised other animals can also regrow their body parts. In this part, we will look into animals that can regrow their organs.


  1. Sharks have the specialty of regrowing their teeth for devouring their prey. They grow teeth throughout their lifetime.


  1. Mexican tetra can develop heart tissues.


  1. Flatworms, according to research, can regrow new heads and regenerate its body.


  1. Starfish can regrow their lost limb and grow a new body. If a hook hooks one of its limbs, it can release the limb and regrow new ones.


How Long Do Axolotls Live?

Axolotls normally live for 10 to 15 years. This doesn’t just happen for your pet to grow old. You have to pay a lot of attention to your standard of living. The water temperature should be perfect for your axolotl’s metabolism. 


The food you feed your axolotls should be meat-based, pellets, or live animals. Pay attention to their behavior in water. Be sure the feeder fish you are providing your axolotls don’t have infections or diseases that can affect your pet. Do not feed your axolotls animals with exoskeleton animals.



Axolotls can regrow some parts of their body except the head. The head is significant, and that is where the regeneration process starts from. The brain commands the blastema to carry out certain assignments. Without the head, your axolotls are dead and won’t function. The brain won’t function if the head is not in place.
