do mexican salamanders had already disappeared completely in the wild world

As of the last update in early 2023, the axolotl (Ambystoma mexicanum), a type of Mexican salamander, has not completely disappeared from the wild. However, they are facing significant threats to their survival due to habitat loss and pollution in their native range around Xochimilco, Mexico City.

The axolotl is critically endangered in the wild, and their numbers have plummeted, making it very rare to find them in their natural habitat. Conservation efforts are crucial to protect and preserve any remaining wild populations.

While few in number, axolotls are not extinct in the wild. Conservationists and scientists continue to work on protecting and restoring habitats, as well as breeding programs to help increase their numbers.

For the most accurate and up-to-date information, it's best to consult the latest reports from conservation organizations or scientific studies. The situation can change rapidly, and ongoing efforts are essential for the survival of this unique and important species.
