Axolotl

Hello. My name is Axolotl, and I want to share my story with you. My name comes from an ancient language of the Aztec people called Nahuatl, and it means 'water dog.' It's a fitting name, because the water is my entire world. I live in a very special place: the canals of Lake Xochimilco, near what is now Mexico City. This lake is the only place on the entire planet where my wild relatives can be found. It is a unique and precious home, woven with history and floating gardens called chinampas. If you were to see me, you might notice the feathery gills that branch out from the sides of my head, which I use to breathe underwater. Many people say my face looks like it is always smiling, a feature that makes my species quite recognizable. But perhaps the most unusual thing about me is that I am a type of salamander that never truly grows up. I keep my juvenile features my entire life, a trait scientists call neoteny. This means I live out all my days in the water, like a tadpole that never becomes a frog, forever a youthful water dog paddling through the canals of my ancestors.

My life is filled with what you might call superpowers. My most famous ability is regeneration. If I lose a limb, it doesn't just heal; it regrows perfectly, without any scars. I can do this with more than just my arms and legs. I can regenerate parts of my brain and even repair my own spine if it is damaged. This incredible skill has fascinated human scientists since the 1800s. They have studied me for centuries, hoping to unlock the secrets of my cellular repair to help people. While scientists observe me in their labs, my life in the wild is a quiet, underwater adventure. I don't swim as much as I walk, using my small legs to stroll along the bottom of the canals. I am a patient hunter. To find a meal, I rely on my ability to sense vibrations in the water. When an insect, a small worm, or a tiny fish comes near, I can feel its movement. Then, with a sudden gulp, I use a suction-like force to pull my prey into my mouth. It is a simple life, but one that is perfectly adapted to my watery home, where I navigate by feeling the world around me.

My story is deeply connected to the history of my home. The Aztec people believed I was connected to a god named Xolotl, who transformed into an axolotl to hide. My journey into the wider world began much later. In 1804, a famous Prussian explorer named Alexander von Humboldt traveled to Mexico. He was the first person to introduce my species to European scientists, sparking a great deal of curiosity. A pivotal moment for my kind happened on October 2nd, 1863. On that day, 34 of my ancestors were carefully shipped from Mexico to Paris, France. This small group would go on to become the great-great-grandparents of nearly all the axolotls living in laboratories and aquariums around the globe today. While my relatives in Europe were beginning their new lives in scientific study, my family back in Lake Xochimilco was facing a different kind of change. During the 20th century, the world around my home began to transform rapidly, and the clear waters of the canals started to face new and difficult challenges that would alter our lives forever.

My world began to shrink as the 20th century progressed. The canals of Lake Xochimilco started to suffer from pollution as Mexico City grew larger and larger around us. The water that had been my family's sanctuary for generations became cloudy and unhealthy. Then, new dangers arrived directly in our home. In the 1970s and 1980s, humans introduced large, hungry fish like tilapia and carp into the lake. These fish were not native to my home and they changed everything. They are aggressive predators that eat the same insects and worms I rely on for food. Even more devastating, they prey on my young, making it incredibly difficult for our population to survive and grow. The impact was dramatic and swift. In the late 1990s, there were thousands of us swimming in the canals. But by 2014, surveys could find almost no wild axolotls at all. Our numbers had dropped to a critical level, and the survival of the wild water dogs of Xochimilco was in serious doubt.

Even though my family in the wild faces great challenges, my story is not over. It has become one of hope and a living legacy. Today, dedicated people are working hard to save us. They are building 'axolotl shelters' in Lake Xochimilco, which are special, protected areas. These shelters have clean water filtered by native plants and are fenced off to keep out predators like carp and tilapia. Here, my wild relatives have a safe space to live and raise their young. I am what is known as an indicator species. This means that my health is a direct reflection of the health of my entire ecosystem. If I am thriving, it means the water is clean and the environment is balanced. My story serves as a reminder of how interconnected life is. By learning about me and the efforts to protect my home, you are helping to ensure that the smiling water dog of Xochimilco continues to swim in these historic canals for generations to come.
