The axolotl is a type of salamander that lives in water. They are often called Mexican walking fish, but they are actually amphibians.
This means that they live both on land and on water. The axolotl can be found naturally only in lakes surrounding Mexico City, but humans have introduced them into other bodies of water as well including Hawaii and California’s Lake Tahoe.
Axolotls have existed for at least 55 million years, dating back to the late Cretaceous period when dinosaurs were alive on Earth! However, fossils found show that these creatures existed millions of years before then when dinosaurs roamed our planet!

What Time Period Did Axolotls Exist?
The scientific name for axolotls is Ambystoma mexicanum. They are a type of salamander, so they have four legs and gills like tadpoles do, but they also have lungs as humans do. This makes them amphibians a creature that lives both on land and in water.
Axolotls have existed for about 300 million years!
The fascinating history of axolotls dates back centuries. In fact, the discovery of these unique creatures can be traced to ancient times. Explore the intriguing story of their origin and the journey of their discovery in our comprehensive article on when axolotls were found.
How Old Are Axolotls?
Axolotls are thought to be the oldest living species on Earth. They have existed since at least 300 million years ago, meaning that they have lived through all of the major geological periods of the planet’s history (the Triassic Period, Jurassic Period, Cretaceous Period, and Paleogene Period).
The axolotl’s evolutionary history is similar to that of other amphibians: it has changed little over time and has remained relatively unchanged for millions of years.
| Age Range | Description |
|---|---|
| Juvenile | Axolotls under 1 year old |
| Young Adult | Axolotls between 1 and 3 years old |
| Adult | Axolotls over 3 years old |
| Longevity | Axolotls can live up to 10-15 years in captivity with proper care |
How Long Have Axolotls Lived On Earth?
Axolotls have been around for more than 250 million years, which means they were there when dinosaurs were roaming the earth. In fact, axolotls are older than mammals, who came into existence about 200 million years ago. And humans only evolved around 200 thousand years ago!
Did you know that axolotls play a crucial role in their ecosystem? These amazing creatures contribute to maintaining the balance of their habitat in numerous ways. Discover the importance of axolotls and their impact on the environment in our insightful article on why axolotls are important.
When Did They First Appear In The Fossil Record?
The first fossil record of this species was found in Puebla, Mexico. It is believed that they lived from the Late Cretaceous period until the end of the Mesozoic era.
The most recent fossils were discovered in Montana, USA. They date back to around 2 million years ago.
Where Did They First Appear In The Fossil Record?
Axolotls are unique in that they can be found on land and underwater. They live in the water as adults, but they spend most of their lives on land.
However, this isn’t their only claim to fame: like other salamanders and amphibians, axolotls can regenerate body parts if needed! If you cut off an axolotl’s leg or tail, it will grow back within weeks!
This unusual animal has been around for millions of years and fossils from 300 million years ago have been discovered in Mexico. Although other species of axolotls still exist today, these ancient creatures disappeared about 65 million years ago when dinosaurs roamed the earth.
To truly understand the historical context of axolotls, it’s essential to know where they originate and thrive in the wild. Dive into the depths of their natural habitat and learn about the regions where axolotls live in our informative guide on where axolotls live in the wild.
How Long Has It Been Since They Went Extinct?
There are still wild axolotls in Mexico, but they haven’t been seen since the 1970s or 1980s. It is believed that this is because of the introduction of non-native fish species into their habitat – these fish prey on axolotls and outcompetes them for food sources.
The axolotl could also be extinct in the United States; it was last spotted in Texas before 1900, and there have been no confirmed sightings since then.
Are They Still Alive Today? (If No, Why Not?)
According to the axolotl Wikipedia page, they were last seen in the wild in the 1960s. They were also last seen alive in captivity around this time as well. Axolotls are not native to any other country, so it is unlikely that they will ever be found again abroad.
| Current Status | Explanation |
|---|---|
| Axolotls are still alive today. | Axolotls are a living species and exist in the wild and in captivity. |
| Threatened | Axolotls are classified as critically endangered in their natural habitat due to habitat loss, pollution, and invasive species. |
| Captive Breeding Programs | Conservation efforts include captive breeding programs to help maintain and protect axolotl populations. |
| Conservation Measures | Various organizations and institutions are working towards conserving axolotls and their habitats. |
| Importance of Preservation | Preserving axolotls is crucial for biodiversity and scientific research purposes. |
Where Can You Find One Today?
Axolotls can be found in the wild in Mexico, and they’re also kept as pets by many people around the world. If you ever find yourself traveling to Mexico, keep an eye out for these fascinating creatures! You might even want to consider taking home one as a pet!
If you don’t want to spend your vacation in Mexico, but still want a chance of seeing one of these unusual amphibians, visit your local zoo or aquarium.
Many zoos are starting to house axolotls as part of their exhibits because they’re such amazing animals who deserve our attention (and maybe even love).
The growth journey of axolotls is a fascinating process. From their initial stages to maturity, these incredible creatures go through remarkable transformations. Gain insights into their growth cycle and discover when axolotls stop growing in our detailed article on when axolotls stop growing.
Do You Think That There Will Ever Be Another Species Like Them Again? Why Or Why Not?
There are other animals that live underwater and on land, but not like axolotls. Axolotls can be regrown from a single limb, which allows them to regenerate into new animals if they’re injured or damaged in any way.
As such, they are very resilient creatures who have lived for millions of years and we may never see another species like them again!
| Possibility | Explanation |
|---|---|
| Yes | There is a possibility of discovering another species similar to axolotls in the future due to ongoing scientific exploration and discovery of new species. |
| No | Axolotls are unique and may not have an exact replica, but there may be other species with similar characteristics or adaptations. |
| Evolutionary Uniqueness | Axolotls have distinct traits, such as their regenerative abilities, which may not be replicated in another species. |
| Environmental Factors | The specific environmental conditions that shaped axolotls’ evolution may be unlikely to occur again, making them highly unique. |
| Scientific Discoveries | New advancements in scientific research may uncover species with similar characteristics to axolotls in the future. |
Are There Any Other Species That Live Underwater But On Land As Well?
So, now that we know what an axolotl is and how long it has been around, let’s look at some other species that live underwater but on land as well.
There are many species of fish that live underwater but on land as well, but none of them have the same ability to regenerate their limbs as axolotls do. So if you’re interested in seeing another animal with these traits, perhaps try looking at some fish instead!
Curious about why axolotls make wonderful pets? These unique amphibians have captivated pet enthusiasts with their distinct traits and care requirements. Learn more about the benefits of having axolotls as pets in our comprehensive guide on why axolotls are good pets.
