10 Interesting Facts About the Axolotls

Aquatic salamanders known as axolotls are only seen in the wild at Lake Xochimilco in Mexico City. Due to their rare capacity to regrow body parts, these critically endangered amphibians are also grown in captivity and are a favorite among pet owners.

The population of axolotls has drastically decreased as a result of habitat degradation and the introduction of exotic fish species. These little frogs have a variety of hues, are small in size, and retain their larval characteristics throughout their entire lives.

They have won the hearts of many people all over the world thanks to their distinctive appearance, which frequently includes bright pink skin and flowery headdresses which are actually their gills. 

These solitary creatures are not hostile or antagonistic, yet they also appear to be very content. Here are the 10 interesting facts about the Axolotls.

1. They Have a Wide Range of Color Patterns

Four distinct genes contribute to the axolotls’ color pigmentation and patterning. Axolotls are often brown or black in the wild, with flecks of gold or olive.

They can change their color to better blend in with their surroundings, just like other salamanders can.

Axolotls that have been bred in captivity are more likely to be albino, leucistic with low pigmentation, or pink in hue.

Axolotls have feathery gills that line the back of their heads, and these gills are colored as well, most prominently in the vivid red color seen in albino axolotls.

2. They Are Native to a Single Country

The axolotl’s natural environment is in critical condition. These aquatic amphibians are only found in the wild in one place: Lake Xochimilco in southern Mexico City, where they were once discovered in two high-altitude lakes in Mexico City.

Their previous residence, Lake Chalco in the heart of Mexico City, was drained to prevent flooding.

Axolotls are rare because of the loss of their habitat and the invasion of tilapia and carp, which are predators, and Xochimilco has been reduced to a network of canals.

3. They Are Carnivorous

Axolotls are carnivores; they consume a wide variety of foods, including fish, worms, insects, and crustaceans.

They aren’t particularly choosy and will consume both living and dead meat. They regularly consume brine shrimp, beef liver strips, earthworms, fish pellets, and other foods in captivity.

Young axolotls and those with insufficient food supplies are more likely to engage in cannibalism by biting off a limb from a close family member.

Thankfully, the damaged axolotl may quickly grow back the body part that was severed because of its capacity for regeneration.

4. They Can Regenerate Body Parts

Axolotls can regenerate jaws, spinal cords, skin, ovary, and lung tissue, even parts of their hearts and brains, which is a step above other amphibians and fish who can only regenerate tails and limbs.

An axolotl can also regenerate all the way through its existence. Researchers who want to apply this skill to people are very interested in the regeneration properties of this animal’s cells.

This is an amazing ability: whereby “In the event that an axolotl loses a limb, a new, perfectly sized and oriented version will develop. The transition between the old and new is seamless within a few weeks.”

5. They Face a Serious Threat

The axolotl is a severely endangered species that exist only in a tiny area of Mexico. Their habitat, which is severely declining as a result of development, pollution, and exotic species, is fewer than four square miles.

Although not necessarily in the wild, their value for scientific research and capacity for captivity breeding should assist secure their survival. It is unclear how many axolotls exist in the wild today.

Moreover, to alleviate food insecurity for low-income households in their habitat, the Mexican government introduced invasive fish species like tilapia and carp.

Conservation efforts have focused on raising the water level of Lake Xochimilco, restoring the axolotls’ natural habitat, and reducing the population of these fish.

6. For the Rest of Their Lives, Axolotls Remain Baby-Like

Axolotls are 鈥�neotenic鈥� animals, which means they retain all of their larval characteristics even after reaching sexual maturity.

As a result, axolotls maintain their distinctive feathery external gills and remain aquatic, unlike many amphibians, such as the salamander, which eventually grow lungs and dwell on land.

Moreover, because they are unable to acquire teeth, they must eat by sucking on food. When they swallow, their mouths occasionally stay open for a little period of time, giving the impression that they are grinning.

Unfortunately for aspiring pet owners, some axolotls have mouths that are slightly tilted up and give the impression that they are smiling constantly. Nevertheless, this is all just a question of looks.

7. Their Romantic Customs Include Dancing

Axolotls can begin mating when they are six months old. The adult animals start by touching one another’s cloacal region, and then they move together in a circular, dance-like motion.

n the wild, females give birth to 100 to 300 eggs once a year; in captivity, this frequency increases. There is no more parental participation after the eggs have been successfully laid. The newborn axolotls are left on their own when the eggs hatch after 10 to 14 days.

8. They Possess a Big Genome

Scientists have a problem when trying to sequence the DNA of axolotls because their genome is 10 times larger than humans’ and contains 32 billion DNA bases.

But it’s a crucial one that will aid in the discovery of the axolotl’s usage of stem cells for tissue regeneration. Two genes that are involved in axolotl regeneration have already been found by scientists.

Scientists are continuing to broaden their research to cover other internal organs and retina regeneration because of axolotls’ remarkable capacity for regeneration.

9. Axolotls are edible to humans

Axolotls were once eaten by the locals of Xochimilco before they were declared an endangered species.

These unusual species can be eaten, and some establishments may still do so today. One restaurant in Osaka, Japan, serves them entire and deep-fried.

Those who have eaten them claim that they are crisp and have a flavor similar to white fish meat.

10. Axolotls may be able to assist humans in the treatment of several illnesses

Due to their regenerating capabilities, which may hold the key to the treatment of many medical issues, axolotls are the salamanders that receive the most scientific research worldwide.

They may hold the key to the cancer mystery because they are a species that is several times more resistant to cancer than mammals. A  study is still ongoing, and scientists and experts are optimistic.
