"Mexico's salamander-like axolotl may have disappeared from its only known natural habitat in Mexico City's few remaining lakes."

"It is disturbing news for an admittedly ugly creature, which has a slimy tail, plumage-like gills and mouth that curls into an odd smile.

The axolotl is known as the "water monster" and the "Mexican walking fish." Its only natural habitat is the Xochimilco network of lakes and canals, which are suffering from pollution and urban sprawl.

Biologist Armando Tovar Garza, of Mexico's National Autonomous University, described an attempt last year by researchers to try to net axolotls in the shallow, muddy waters of Xochimilco as "four months of sampling zero axolotls".""
