Fun Facts About Axolotls

In the game Minecraft, there are cute little axolotls that children love to collect. They come in a variety of colors... gold, brown, pink (leucistic), cyan, and blue... and can be found swimming in the clay pools found in lush caves. Many children are surprised when they find out that axolotls are animals that exist in real life and not just in the Minecraft realm. What are axolotls like in real life? Keep reading to find out!

Seven fun facts about axolotls. Learn about where axolotls come from, the life cycle of axolotls, what axolotls eat, and why axolotls are endangered.

Axolotls are amphibians.

Amphibians are animals that emerge from eggs in the water and take to the land as adults. But not axolotls! Axolotls are unique amphibians because they spend their entire lives underwater. 

Female axolotls lay 300 to 1,000 eggs at a time. These embryos will emerge from their eggs in approximately two weeks.

Axolotls are native to Mexico.

Wild axolotls can only be found in Lake Xochimilco and in the canals near Mexico City. They live in stagnant freshwater that remains about 20°C (68°F) year-round.

Axolotls are 'paedomorphic'.

The life cycle of axolotls is similar to other amphibians with one major exception... at five weeks old when their legs are fully formed, their metamorphosis stops. Axolotls are paedomorphic because they retain some of their youthful traits into adulthood. They keep their tadpole-like tails and feet and depend on their gills to breathe underwater.

Terrestrial axolotls are rare but do exist.

Although extremely rare, there are axolotls that go through a complete metamorphosis and adapt to living on land. Very little is known about terrestrial axolotls and no one knows exactly how or why this happens. We do know a few things though. We know that terrestrial axolotls live on land, breathe air with their lungs, are carnivorous, and look significantly different from aquatic axolotls!

Axolotls are carnivorous.

Axolotls are strict carnivores, meaning they only eat meat. Axolotls eat worms, insects, small fish, mollusks, and just about anything else that can fit inside their mouth and swallow whole. They will even eat salmon eggs and other axolotls.

Axolotls are able to regrow missing limbs.

When axolotls lose their limbs due to injury or predation, their limbs regrow over time. It can take aquatic axolotl limbs 40 to 50 days and terrestrial axolotl limbs 155 to 180 days to rejuvenate. Scientists are closely studying axolotls to learn as much as they can about how axolotl limbs rejuvenate. Maybe someday these scientists will be able to use their discoveries to regrow human limbs!

Axolotls are a critically endangered species.

Even though we see axolotls in pet stores, aquariums, and zoos, they are a critically endangered species. This means they are almost extinct in the wild. Scientists estimate there are only 500-1,000 axolotls in the wild. Habitat destruction due to water pollution, invasive fish species, human development, and drought are some of the leading causes of the decline in axolotls. Another cause of their decline is overfishing by humans. Some people capture axolotls to sell as pets... whereas others sell them for food.
