Axolotl is unique, attracting Amphibians who fascinate their visitors with their beautiful appearance and intriguing lifecycle. Axolotl are scientifically known as Ambystoma mexicanum who are native to Mexico. In this blog post, We will explore the amazing transition of Axolotl from a larva to a young land dwelling adult.
Beginning of Axolotl Birth
First of all, there is a formation of eggs which are laid in huge numbers. These eggs remain in the mother’s womb under a protective layer. The embryo inside the egg has an approximate size of 2mm in diameter. The embryo is protected with a layer of jelly, just like an egg. This jelly works as a protein for the embryo. When an embryo is about to hatch, it becomes 11 mm in diameter.
Hatching
The embryo grows extensively in the egg and waits for the right time to hatch. When an embryo is hatched, it is called larvae. At this stage, their skin is quite apparent. There is no growth in any limbs.
Larvae
At this stage, there is a growth in their limbs. First, their front legs grow, and then their back legs grow. The fins and feathery parts grow and this little Axolotl brings a smile on its face. Now, two weeks have passed since the Larvae has come out.
Adulthood
Now, larvae are fully developed and have reached adulthood. However, they are not mature enough and can grow bigger in size. They have fully developed and thickened their skins.
Transformation
Axolotls are Amphibians who have the option to undergo Metamorphosis or remain in their natural state without undergoing any changes, and they possess the same juvenile properties. Most Axolotls remain loyal to their natural aquatic properties of existence. However, some may undergo Metamorphosis in which they adapt to terrestrial life and prefer to live on land.
Regeneration
Regeneration is one of the peculiar properties of Axolotls. They can reproduce their lost limbs and broken body parts and may heal their spinal cords as well. The study of Axolotls’ regeneration properties will surely help make progress in human regeneration methods.
Reproduction
Axolotls show dancing movements and twirling their bodies in the season of courtship. They try to convince each other with their lovely moves. If a pair is agreed for courtship, male releases its firm which the female Axolotl adapts on her will and lays a large number of eggs which have the hopes of starting a new generation of Axolotl.
Guardian of Eggs
Axolotls are few of those aquatic animals who take care of their eggs and protect them from any predators’ attack. This phenomenon is not very common in aquatic animals. They lay their eggs on aquatic plants and other safe surfaces in the water. They ensure that these eggs are kept in a safe place where they can be hatched protectively.
Why Do Some Axolotls Not Exhibit Metamorphism?
Genetic Factors
Many Axolotls are unable to adapt to terrestrial states due to some genetic factors. Some Axolotls lack thyroid glands, which does not necessitate the development of organs that are essential for their adaptation to a terrestrial state.
Survival Advantage
Axolotls have more benefits in an aquatic environment. They have the ability to regenerate their limbs and broken body parts, which can only be exhibited in the water. Aquatic environments also help Axolotls to breathe under the water with their gills. These are the reasons why some Axolotls do not exhibit Metamorphism.
Sexual Maturity in Axolotls
There are different ages for both genders to reach their sexual maturity. Males reach adulthood slightly earlier than female Axolotls. We can identify them with their stretched-out body and long tails. However, We observe additional changes in white, albino Axolotls. When they reach their adulthood, their toes become dark brown from the tips.
Sexual Attributes in Males
Male Axolotls do not produce sperm right after they reach adulthood. This situation is seasonal in the wild, but in captivity, there may be regular instances of this problem. They need the first two months to produce sperm and the next 2-3 months to allow them to come into a tube from where they will be released for mating.
Frequently Asked Questions
How many stages of life do Axolotls have?
There are three stages of Axolotls’ life cycle, which are listed below.
Egg stage
Larvae stage
Mature Axolotl
Can axolotls live outside of water?
Axolotl is an aquatic animal. It has the properties of an aquatic animal. However, some Axolotls may undergo Metamorphosis, which is when they adapt to terrestrial life.
How long do axolotls live?
Axolotl’s lifespan depends upon the care and diet they are fed. If they are kept in good aquatic conditions with balanced water parameters, they can live up to 10-15 years in a captive environment.
How old is the oldest Axolotl?
The oldest Axolotl is known to have lived for 25 years.
Are axolotls endangered?
Axolotls are considered endangered due to the destruction of the habitat they live in and water pollution.
Can axolotls live outside of water?
Axolotls are aquatic animals that mostly live in water. However, some may undergo Metamorphosis and adapt to terrestrial life.
Are Axolotls Predators?
Despite being smiley and attractive, Axolotls are considered good predators. They do not prey in the morning and hide under the mud to save themselves from the attack of predators. However, they become an active predator at night and look for prey such as small insects, bloodworms, crustaceans, mollusks, etc.
How long do Axolotls take to grow?
Axolotls have slow physical growth. It takes them months to grow. If they are kept in a good water environment where they are provided with suitable water parameters and a balanced diet, it will take them 12-18 months to reach their full adult size.
Conclusion
Axolotls are unique Amphibians who have beautiful appearance. They undergo a unique lifecycle from a larva to a mature Axolotl. They amaze the observers with their regenerative capabilities. Learn more about fish and other aquatic animals.
