Axolotls are cute, cuddly creatures that live in lakes and rivers all over Mexico. They’re an ancient species of salamander, a group of animals that includes frogs and newts. Axolotls spend their lives almost entirely underwater, but they can breathe air too.
Their most distinctive feature is their frilled gills these are rows of small flaps along both sides of their bodies which help them breathe oxygen from the water when they’re submerged or on land. So why do axolotls have frills?

| Frills in axolotls are a unique and interesting feature that contributes to their overall appearance. |
To stay cool
In the wild, axolotls are nocturnal animals that spend most of their time in the water. They rely on this cool environment to help regulate their body temperature, which is why you’ll often see them hidden under rocks or logs during the day.
When they do come out to bask in the sun, they do so very briefly and only briefly enough to absorb heat before returning to their dark hiding spots.
Axolotls have a lot of blood vessels all over their skin and gills, which helps them stay cool as they absorb heat from outside sources (the sun), as well as release it through evaporation and respiration. Because axolotls don’t sweat like we do when we’re hot (thank goodness), this is a pretty important process for them!

To show off their muscles
They’re strong. The axolotl is a very powerful animal and can lift its own weight up to 10 times in a row.
They can jump a long way. Axolotls have been known to jump up to 3 feet (1 meter) from the water surface, which is equivalent to jumping from a 5-story building.
They can swim fast. An adult axolotl can swim about 1 mph (1.6 km/h), which means that it takes just under one minute for their bodies to cover 100 feet (30 meters). This speed allows them to escape predators and find food more easily, but it also makes them easy prey for larger animals such as fish or humans!
They stay underwater for long periods of time upwards of 20 minutes at once! while still being able to breathe through their skin’s gills with no problem whatsoever because they have lungs too so they don’t get tired easily either way.”
To scare predators
The frills of the axolotl are there to scare predators. While they may look cute and harmless when you see them swimming around in your aquarium, their appearance is actually quite terrifying. If a predator comes too close to an axolotl, it will open its mouth wide and flare out the frills on its neck.
This makes the animal appear much larger than it really is. The frills also irritate the gums of any fish that tries to eat an axolotl, making them want to bite at something else instead!
Axolotls can be very aggressive towards other animals when they want food or territory. They are known for biting humans who come too close to them – even though this rarely causes serious damage or pain (it just feels like being bitten by another fish).
Axolots have sharp claws on their hands and feet which make them strong enough for hunting prey that swims above water surface level where you can’t see well enough with only two eyes instead of four like most predators have used since evolution began millions years ago.’
| Defense Mechanism | Description |
|---|---|
| Camouflage | Ability to blend into the surroundings |
| Mimicry | Resembling another organism to deter predators |
| Startle Response | Sudden and unexpected movements or sounds |
| Spines or Thorns | Physical deterrent with sharp protrusions |
| Venom | Injecting toxic substances for defense |
To warn other animals that they’re toxic
You may have noticed that axolotls have frills. What’s the deal with those? Well, it turns out that the frills aren’t just for looks—they’re also a warning to predators.
The dark-colored spots on their skin contain a chemical called tetrodotoxin (or TTX), which is deadly if ingested by other animals. This poison acts as a defense mechanism, keeping predators away from these aquatic salamanders.
The axolotl’s frill acts as an extra layer of protection against predators that would be attracted to their bright colors and patterns throughout natural environments such as lakes or ponds. When threatened by these hungry animals, axolotls will expose their frills and use them to scare off potential threats!

Because they were a gift from the God
The god was a scientist who wanted to see what would happen if he put a human brain into an axolotl. He succeeded, and the axolotl was born with a human brain.
The god gave it the frills as a gift because he thought they were cute and would make him look even more intelligent, which is why all axolotls now have frills on their heads.
To show that they’re related to ferns
The frill is an evolutionary remnant. The axolotl’s ancestor was a type of fern called an Azolla, which had leaves that were also frilled around the edges. In fact, Azolla is still around today and can be found growing in marshes and other wet places across the world.
The frill functions as a kind of leaf that collects nutrients from the water around it just like a real fern would do with its actual leaves! It also protects the axolotl’s brain from bumps and bruises when trying to escape predators or other dangers in their habitat (like us).
| Characteristic | Description |
|---|---|
| Leaf Structure | Fronds with delicate, feathery appearance |
| Reproductive Method | Producing spores instead of seeds |
| Moisture Dependency | Requiring moist environments for optimal growth and survival |
| Vascular System | Possessing specialized tissues for water and nutrient transport |
| Ancient Lineage | Evolutionary lineage dating back millions of years |
To get rid of salt in the blood
The axolotl’s frill is actually a third lung, and it helps to remove salt from the blood. The axolotl has a very low metabolic rate, which means it doesn’t need much food. This makes them ideal for people who have trouble feeding themselves—or even remembering to eat!

Because they’re related to dinosaurs
Well, sort of. They’re actually part of a group called the ‘Amphibian’. This means they can both live on land and in water, which is where they get their name (‘Amphibian’).
Axolotls have a similar bone structure to many other species of amphibians but they also share some similarities with reptiles and birds, including their skin texture and metabolism.
The only difference between axolotls and dinosaurs is that they’re bigger and really much better looking! If you want to learn more about these amazing creatures you should visit your local library or museum (or google it).
Because they’re amphibians with four legs as well as gills
The frills on the sides of the axolotl’s head help them balance when they’re walking around on land. Axolotls have four legs and two lungs, so they can breathe air and water. This makes them amphibians animals that can live both in water and on land.
Like most amphibians, axolotls are cold-blooded animals that need to warm up before they can move around or hunt for food. When it’s cold outside (and during winter), an axolotl will stay inside its aquarium at room temperature until it warms up enough to start moving around again.
If you’ve ever wondered why our friends from Mexico City look like sippy cups with legs, now you know!
Because axolotl females find frills attractive
Frills are an attractive physical characteristic for axolotl males, who want to attract as many mates as possible. The frill also shows off their muscles and makes them look big and strong, like a lion’s mane does. It may also help to show that they’re related to ferns, because their ancestors have been around since prehistoric times when dinosaurs roamed the earth.
Explore the captivating world of axolotls and their unique external gills. Our expert analysis on why do axolotls have external gills delves into the evolutionary significance of these remarkable features and sheds light on how they contribute to the survival and adaptation of axolotls.
To look threatening when their mouths are full of food
When you look at an axolotl, you might think it looks like a gentle little creature. However, if you got too close and tried to pet one, it would probably bite or pinch you with its sharp teeth.
This is because axolotls have a frill that acts as a warning signal when they have their mouths full of food. The frill also helps show off their strength by displaying large muscles underneath it.
The frill is one of the most distinct features in the axolotl’s body; unlike other salamanders which use their front legs to push themselves forward on land, the axolotl relies solely on its tail to move around land because its front legs are used for swimming instead!
Another interesting thing about this species is that even though they have lungs, they prefer water over land due to all kinds of reasons such as temperature control during winter (cold blooded animals tend towards warmer temperatures).
So that their limbs don’t float away (maybe not)
You might think that these frills are there to help keep the axolotl’s limbs from floating away. It’s true that axolotls have a very slimy skin, but this doesn’t necessarily mean they can’t swim with their legs.
Axolotls are amphibians and therefore have gills as well as lungs, so they can breathe either in water or on land. However, even though their bodies aren’t particularly dense compared to some other animals’, it’s still possible for them to sink if they don’t hold onto something like their tail!
It’s more likely that those frills evolved over time because of an adaptation that helps axolotls breathe better while under water. But why would you care about breathing when you live underwater?
Well…you might not want your body getting too heavy with all those extra layers of fat laying around! By developing these flaps along its neck area (which actually aren’t just there for decoration), this species can easily get rid of excess fat without having to worry about losing its head.#ENDWRITE

Dive into our enlightening article on reasons why axolotls can regenerate to uncover the biological mechanisms and unique factors that enable axolotls to regenerate their tissues and organs with astounding precision.
Because they’re very old and haven’t changed much since primitive times
Why are axolotls called water dogs? Probably because they look like a big, weird dog. Axolotls have a body that’s about the size of your arm, with four stubby legs and two little fins on their back. They also have large, round heads, bulging eyes and long snouts that can make them look like mini-alligators. Their mouths are full of sharp teeth (don’t worry they’re not planning on eating you).
But what makes axolotls so unique is their frill: A series of folds along the sides of their bodies that helps camouflage them against rocks or plants in the wild.
If you’re thinking this sounds similar to frills you see on snakes or lizards today you’re right! Reptiles descended from ancient amphibians just like axolotls did (but we’ll talk more about that later).
| Characteristic | Description |
|---|---|
| Neoteny | Retention of juvenile characteristics into adulthood |
| External Gills | Gills located outside the body for respiration |
| Regeneration Ability | Ability to regrow lost or damaged body parts |
| Lack of Metamorphosis | Remaining in larval form throughout their lives |
| Genetic Stability | Relatively little genetic change over long periods |
Conclusion
But there are so many reasons why they have frills! One of the main ones is that they’ve been around for so long, and haven’t changed much since primitive times. They’re also very strange looking creatures, with just their heads sticking out of their gills.
That’s another reason why they might have frills: because when a predator sees them coming at them with these weird fins on their heads, it makes them think twice about attacking!

FAQs
Why do axolotls have external gills?
Axolotls have external gills as a result of neoteny, which is the retention of juvenile traits into adulthood. These gills allow axolotls to efficiently extract oxygen from the water and are a distinguishing feature of their unique biology.
Can axolotls regenerate their limbs?
Yes, axolotls are renowned for their exceptional regenerative abilities. They can regrow lost limbs, including limbs that have been amputated or damaged, through a process called epimorphic regeneration.
How long do axolotls live?
Axolotls have an average lifespan of 10 to 15 years in captivity, although some individuals have been known to live even longer. Providing them with proper care, a suitable environment, and a nutritious diet can contribute to their longevity.
What do axolotls eat?
Axolotls are carnivorous and primarily eat small aquatic creatures like worms, insects, small fish, and crustaceans. Their diet can also include commercial axolotl pellets and certain types of live or frozen food suitable for their size and nutritional needs.
Can axolotls live outside of water?
Although axolotls are amphibians, they are fully aquatic and are not adapted for living outside of water. Unlike other amphibians, they do not undergo metamorphosis and remain in their larval form throughout their lives, retaining their gills and aquatic lifestyle.
