Ambystoma dumerilii (Lake Patzcuaro salamander)
The Lake Patzcuaro Salamander, locally known as Achoque, Ambystoma dumerilii, is a neotenic salamander species. This salamander is found in Lago de Pátzcuaro, a high altitude lake in the Mexican state of Michoacán. This is located in the Mesa Central region of the country, home to many isolated Ambystoma species. There have been claims that a subspecies is found further inland to the north-east in San Juan del Río, Querétaro, but this is doubtful due to the animals wholly aquatic nature.
The Lake Pátzcuaro salamander exhibits some highly unusual and distinct features, indicative of its evolutionary distinctiveness, including its rare neotenous life history, whereby the species never develops into an adult but instead retains its juvenile characteristics throughout life, essentially achieving reproductive maturity whilst still in its undeveloped larval form. The salamanders are harvested both for human consumption and for medicinal purposes as they are thought to be effective in addressing respiratory problems. Known only from Lake Pátzcuaro (or Lago de Pátzcuaro) in north-western Michoacan, Mexico, it is crucial that this habitat is conserved to secure the future survival of the species.
