the species name ambystoma mexicanum is sometimes also called mexican salamanders

Yes, that's correct. The species name "Ambystoma mexicanum" refers to the same unique amphibian you've been inquiring about, which is not only known as the Mexican axolotl but also as the Mexican salamander. Like all axolotls, members of this species have distinctive characteristics:

1. Pedomorphosis (Neco-tenancy): They retain larval features throughout their entire natural lifespan, including a neotenic appearance with external gills and dorsal fins.

2. Regenerative Abilities: One of the most remarkable aspects of these creatures is their ability to regenerate lost body parts, including limbs, portions of their spinal cord, and other organs.

3. Aquatic: They are exclusively aquatic and live in specific environments like underground ponds, caves, and springs in regions around Texcoco, Chalco in Mexico.

4. Conservation Status: Given the limited distribution and habitat loss in their natural range due to urbanization and pollution, the axolotl is critically endangered in the wild.

5. Lab Subjects: Their unusual biology makes them valuable subjects for studies on life cycles, neuroscience, and regeneration, providing insights that are highly relevant in fields like evolutionary biology and potential medical applications.

While Ambystoma mexicanum is more commonly referred to as the axolotl among the general public, calling them Mexican salamanders is also accurate and reflects their taxonomic classification within the broader group of salamanders.
