are mexican salamanders disappeared completely in the wild

As of my last update, axolotls (Ambystoma mexicanum), often referred to as Mexican salamanders, are critically endangered in the wild and are on the brink of extinction due to various factors. Let's discuss their current status:

1. Habitat Loss: The primary reason for the severe decline in their population is the loss of their natural habitat. Urbanization and pollution around the Mexico City area have dramatically reduced the water bodies where axolotls used to live.

2. Pollution: Water pollution from agriculture and industry can be harmful to axolotls, making it difficult for them to survive in the wild.

3. Wild Populations: It has been reported that sightings of wild axolotls have become extremely rare, with some suggesting they may already be locally extinct in parts of their native range.

4. Captive Conservation Efforts: Due to their threatened status in the wild, many efforts are being made to conserve axolotls through captive breeding programs in zoos, research institutions, and among hobbyists. These initiatives aim to preserve their genetic diversity and potentially reintroduce them into suitable habitats in the future.

5. Conservation Status: The axolotl is listed as "Critically Endangered" on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.

It's important to note that conservation efforts are ongoing, and while the outlook is challenging, there is still hope for the axolotl. Continued work in habitat restoration, captive breeding programs, and public awareness campaigns can play vital roles in preventing their complete disappearance from the wild.
