Axolotls are incredibly unique animals, and they are just as interesting as they look! From their distinctive looks to the interesting things their bodies can do, keep reading to learn more about axolotls!


Question 1. What Are Axolotls?

Axolotls are amphibians. This means that they are cold-blooded vertebrate animals. Amphibians are distinguished by having a gill breathing larval stage followed by an adult stage of breathing with lungs on land. They are neotenic salamanders, which means that they retain their juvenile features throughout their entire lives. This is why they live their entire lives underwater instead of eventually moving onto land. They have gills and lungs and they use both.


Questions 2. Where Are Axolotls Native To?

Axolotls are only found in the wild in the lake complex of Xochimilco near Mexico City. Due to pollution and predators, they are critically endangered in the wild, but they are becoming very popular as pets! Even though female axolotls lay hundreds of eggs at a time, there are an estimated 1000 axolotls or fewer left in the wild today.

Question 3. How Big of a Tank Do You Need for an Axolotl?

A single axolotl needs at least 20 gallons, but you can't have too big of a tank. It is also recommended to add 10 gallons per additional axolotl. It is best to choose a tank with lots of floor space since axolotls are bottom dwellers and once they get older they don't swim a whole lot. 20-gallon long and 40-gallon breeder tanks are both excellent choices for axolotls.

Question 4. What Are Those Things on Axolotls Heads?

The fluffy things that branch off of axolotl's heads are gills! The "feathers" that are on their gills increase surface area, which means that a larger volume of gas is able to be diffused into the blood. This makes their gills much more efficient.

Axolotls are unique because they have both gills and lungs. They can use their gills to get oxygen under water, but sometimes you will see them swim up to the top to get a gulp of air.

Question 5. Axolotls Are?

Axolotls are carnivores! They don't need to eat any plant matter at all, although they aren't great hunters and will suck up anything that will fit in their mouths. They do well eating worms, small fish, insects, and various other small creatures in the wild. They will even eat another axolotl if given the chance.

In captivity worms or pellets are generally the best food for them, but there are other options. This article goes over all of the different food options for pet axolotls.

Question 6. Why Are Scientists So Interested in Axolotls?

Scientists are interested in axolotls because of their ability to regenerate limbs and organs. While it is true that there are other animals who can regenerate limbs, salamanders are the only vertebrate with the ability. Axolotls are also able to regenerate the front portion of their brain, their spinal cords, and a third of the heart ventricle, which is unique to the species.

When humans get injured the wound gets covered with skin tissue, but when axolotls get injured all of the cells that are close to the injury get turned into stem cells, and they are able to fix whatever is injured. Scientists hope that studying the axolotl genome could reveal methods of regenerating tissue to be used in medical research.


Question 7. What Is the Average Axolotl Lifespan?

The average axolotl lifespan is 10-15 years in captivity. There have even been cases of well cared for axolotls living up to 20 years. In the wild, their lifespan is much shorter. They are not very quick and they don't have any natural defenses, so it is unlikely to see an axolotl older than 5 years.
