The axolotl is a unique aquatic salamander native to the lakes of Mexico, particularly Lake Xochimilco. Unlike most amphibians, axolotls remain in their larval form throughout their lives, a phenomenon known as neoteny. They have external gills, a wide head, and a long body, making them easily recognizable. Axolotls are known for their remarkable ability to regenerate lost body parts, including limbs, spinal cord, and even parts of their heart and brain. This regenerative capability has made them a subject of scientific research, particularly in the fields of regenerative medicine and genetics.
