Answer

Scientists find it difficult to classify the axolotl because it possesses characteristics of both fish and amphibians. For example, the axolotl has gills, which is a feature typical of fish, allowing it to breathe underwater. Additionally, it has legs and feet, which are characteristic of amphibians, enabling it to move on land. This mix of traits complicates its classification within the traditional biological categories.
