What is an Axolotl?
An axolotl (pronounced “AX-oh-lot-ul”) is a type of salamander, but with a key difference from other salamanders.
| Information | Details |
|---|---|
| Common Name | Axolotl, Mexican Walking Fish |
| Scientific Name | Ambystoma mexicanum |
| Type | Amphibian (Salamander) |
| Origin | Mexico |
| Habitat | Freshwater lakes and canals (Lake Xochimilco) |
| Size | Up to 12 inches (30 cm) |
| Lifespan | 10-15 years in captivity |
| Diet | Carnivore (worms, insects, small fish, crustaceans) |
| Colors | Pink, white, black, gray, golden, albino |
| Conservation Status | Critically Endangered in the wild |
While most salamanders grow up and leave the water to live on land, axolotls stay in their juvenile form their whole lives and remain in water forever!
Scientists call this being “neotenic,” which means they keep their baby-like features even as adults.
Though they’re nicknamed “Mexican walking fish,” axolotls aren’t fish at all! They’re amphibians, just like frogs and toads, but they never leave their watery home.
Unlike many pets such as dogs that need daily walks, axolotls spend their entire lives in water.
Brilliant Facts About Axolotls
Get ready to be wowed by these cool axolotl facts!
These water creatures might look strange, but they’re full of surprises that will make you see why scientists and pet lovers find them so special. Let’s look at what makes axolotls truly one-of-a-kind!
1. Axolotls are amphibians, but unlike most amphibians, they stay in water their entire lives.
Unlike frogs and salamanders, axolotls never undergo metamorphosis to develop lungs for land living. They stay fully aquatic throughout their life.
2. Some people call them Mexican walking fish, even though they aren’t fish at all!
This nickname comes from their appearance and the way they sometimes walk along the bottom of their watery homes.
3. Axolotls come from lakes near Mexico City, particularly Lake Xochimilco.
These freshwater lakes once covered much of the Valley of Mexico but are now greatly reduced in size due to urban development.
4. Axolotls can grow up to 12 inches (30 cm) in length when fully grown.
Females are typically slightly larger than males, though telling them apart can be difficult for most people.
5. Axolotls are quiet animals and don’t make any sounds.
They communicate mainly through chemical signals in the water and body language, not vocalizations like frogs or many other animals do.
6. Axolotls are a type of salamander that stays juvenile throughout its life.
This rare condition is called neoteny, where they keep their larval features even as adults, making them quite unique.
Physical Characteristics
7. They have external gills that look like feathery branches on the sides of their heads.
These special gills allow them to extract oxygen from water and are one of their most distinctive features.
8. Axolotls have four legs and can walk on lake bottoms, but they mostly swim.
Their legs have unique toes, with four on each front foot and five on each back foot.
9. Axolotls can be pink or white, but they also come in black, gray, or golden colors.
Their coloration depends on genetics, and breeders have developed many different color variations for pet axolotls.
10. Axolotls don’t have eyelids, so their eyes stay open all the time!
Their eyes are small and dark, usually black or very dark brown, and positioned on either side of their head.
11. Their hearts beat slowly compared to humans, which helps them live in waters with little oxygen.
Their circulatory system is specially adapted to work efficiently in their cool aquatic environment.
12. They breathe through their gills and also have lungs, though they rarely use them.
Axolotls can actually breathe in three ways: through gills, lungs, and even through their skin.
Special Abilities
13. Axolotls can grow back body parts, including legs, tails, and even portions of their heart and brain!
This incredible regeneration ability makes them very valuable to scientists studying tissue repair and regrowth.
14. They can grow back entire limbs, which is one of their most remarkable traits.
Within weeks of losing a limb, they begin developing a new one, complete with bones, muscles, and nerves.
15. Axolotls can grow back parts of their spinal cord if hurt, which very few animals can do.
This amazing healing power is why researchers study them to help develop treatments for human spinal cord injuries.
16. Axolotls can live up to 15 years, although many live around 10 years.
Their lifespan depends on proper care including clean water, appropriate temperature, and a good diet of healthy foods.
Diet and Behavior
17. Axolotls eat meat and enjoy worms, insects, and small fish.
They are carnivores with a big appetite, and young axolotls sometimes accidentally bite each other’s limbs, which then regrow!
18. They have an excellent sense of smell and can find food even in murky water.
They use this keen ability to locate prey, and can detect food that’s hidden or buried under sand or small rocks.
19. Axolotls react strongly to temperature changes and need cool water to stay healthy.
The ideal temperature is between 60-64°F (16-18°C); warmer water speeds up their metabolism but shortens their lifespan.
20. They have a very slow metabolism, which means they don’t need to eat often.
Adult axolotls can sometimes go up to two weeks between meals, though they’re usually fed several times per week.
21. Axolotls get along well with others and don’t mind sharing their tank with fellow axolotls.
However, they sometimes nip at each other, so it’s best to keep similarly sized axolotls together.
Conservation
22. Wild axolotls are at risk of disappearing because their natural home is getting smaller.
Pollution, urban development, and introduced fish species all threaten the remaining wild population of these special salamanders.
23. In nature, axolotls face threats from pollution and habitat destruction.
Scientists estimate fewer than 1,000 wild axolotls remain, making them critically endangered in their native habitat around Mexico City.
24. Unlike some animals like the Arctic fox that can adapt to harsh environments, axolotls need very specific water conditions to survive.
This makes them especially vulnerable to environmental changes.
Scientific Importance
25. Scientists study axolotls because of their ability to grow back body parts.
Their cells can transform into different cell types during regeneration, a process called dedifferentiation that fascinates medical researchers worldwide.
26. Researchers use axolotls to learn about human diseases because of their healing abilities.
Their unique genome was fully sequenced in 2018, helping scientists understand the genetic basis of their remarkable regenerative powers.
Habitat and Care
27. Axolotls thrive in cool, clean water and need a special tank to stay healthy.
They prefer dimly lit environments with minimal water movement and plenty of hiding places to feel secure and comfortable.
28. Many people keep axolotls as pets, but they need special care and a clean, cool water tank.
They require specific conditions including proper filtration, regular water changes, and careful monitoring of water quality.
29. They can survive in different water types, including fresh or slightly salty water.
In captivity, they need properly treated water free of chlorine and chloramine, which are harmful chemicals found in tap water.
30. Axolotls don’t need to leave the water to breathe, unlike other amphibians.
While many salamanders transform to breathe air and live on land, axolotls remain aquatic their entire lives, making them unique.
Fun & Interesting Facts
31. They can grow back their brains!
If an axolotl loses part of its brain, it can actually make new brain tissue. This ability to create new brain cells is extremely rare and makes axolotls very special to scientists who study healing.
32. Axolotls can survive without their heart for a while!
Researchers have found that axolotls can live without their heart for short periods. Their ability to make new tissue and adapt to hard situations is part of what makes them so interesting!
33. They chase their food!
Axolotls have been known to follow their meals. When they spot something to eat, like a worm or a small fish, they will often use their keen sense of smell to track it down, sometimes even pursuing their dinners!
34. Axolotls stay young forever!
Unlike most amphibians, axolotls don’t go through the normal growing-up process. They keep their young, water-loving form throughout their lives, so they’re forever “kids” in the amphibian world!
35. They seem to have a friendly face!
The way axolotls’ mouths curve up in a slight smile-like shape has made them popular among animal fans. This “smile” doesn’t mean they’re happy, but it certainly makes them look cute!
36. Axolotls are champions of healing!
They can make new limbs and also vital organs such as their heart, spinal cord, and even parts of their eyes. They’re like the champions of the animal kingdom when it comes to fixing themselves!
Why Are Axolotls Endangered?
In the wild, axolotls face many challenges that put their survival at risk:
- Lake pollution: Waste from Mexico City has made their water dirty
- Habitat loss: Their lakes are shrinking as cities grow
- Introduced fish species: New fish brought to their lakes eat baby axolotls
- Climate change: Changing water temperatures affect their health
Conservation groups are working to protect the remaining wild axolotls by cleaning up Lake Xochimilco and creating protected areas where these special creatures can live safely.
How to Care for an Axolotl as a Pet
If your parents are considering an axolotl as a pet, here are some important care tips:
- Tank size: At least 20 gallons for one axolotl
- Water temperature: Keep between 60-64°F (16-18°C)
- Water quality: Clean, dechlorinated water with regular partial changes
- Substrate: Fine sand or bare bottom (no gravel that could be swallowed)
- Food: Worms, high-quality axolotl pellets, or small pieces of fish
- Tank mates: Best kept alone or with other axolotls of similar size
- Lighting: Low light, as bright lights stress them out
Remember, axolotls are a commitment and need special care to stay healthy!
