Even more, an axolotl can continue to renew its tissues throughout its life. The regenerative capabilities of the cell’s in this amphibian are fascinating to scientists who are hoping to translate this feature to humans.

2. Axolotls look like babies forever

Axolotls are neotenic, which means they develop into adults without losing their larval characteristics.

Axolotls look like babies forever

While many amphibians, such as the salamander, eventually acquire lungs and move onto land, axolotls retain their feathery external gills and stay aquatic. Because of this, they never develop teeth, and they must use a suction technique to eat.

3. They have different color patterns

Axolotls have four different genes that influence their coloration and patterns. In the wild, axolotls are typically brown or black with gold or olive speckles. They may also alter their color to better blend in with their surroundings, like other salamanders.

The lighter colored axolotls, including albino, leucistic (with reduced pigmentation), and pink, are more common in animals that have been bred in captivity. The gills on the back of an axolotl’s head are also pigmented and are feathery and crimson.

The impossibly silly branches that grow from the axolotl’s head might not seem practical, but they’re the salamander’s gills. The filaments attached to the long gills increase the surface area for gas exchange.

5. They can live up to 15 years!

When kept in captivity, an axolotl may live for 10 to 15 years, with a median age of 12 years. It’s important to emphasize that only well-cared-for axolotls reach this age.

In the wild, they will generally live between 5 to 10 years.

If you’re planning to get an axolotl, you should be prepared to take care of a lot of babies! It’s not a good idea to keep males and females in the same tank for long because they’re highly axolotls are prolific breeders, and females can lay up to 1,000 eggs at a time.

It’s unusual for an axolotl bite to leave a scar, and the teeth aren’t sharp enough to harm you. Axolotls will also most likely require assistance—they aren’t very skilled at capturing their meals.

8. Axolotls are endangered species

The axolotl, which is only found in one small region of Mexico, is critically endangered in the wild. They have less than four square miles of habitat that has been affected by development, pollution, and invasive species.

Axolotls are endangered species

These amphibians might be important to scientific research and may be bred in captivity, but they will not necessarily survive in the wild. In 2009, experts predicted that their population had decreased by 90%. They were declared extinct in the wild in 2015, but one was rediscovered a week later.

Fun fact!

The axolotl pronunciation is ‘ACK-suh-LAH-tuhl’ in English. The term comes from the Nahuatl language, which is derived from the Aztecs. The name may also be derived from the Aztec god Xolotl. If you’re seriously considering getting an axolotl, be sure to also check our list of cute axolotl names
