Lake Xochimilco, Mexico City (Amanecer en Xochimilco). The native habitat of axolotls is important to the study of preservation and conservation. Wild form. The axolotl is native only to the freshwater of Lake Xochimilco and Lake Chalco in the Valley of Mexico. Lake Chalco no longer exists, having been drained as a flood control measure, and ...
It is endemic to Mexico and only known from its type locality in the Sierra Madre de Oaxaca near Totontepec Villa de Morelos, Oaxaca. [1] [2] [3] The natural habitat of Pseudoeurycea aquatica is cloud forest at about 2,100 m (6,900 ft) above sea level. It lives aquatically in streams, the only plethodontid salamander in Mesoamerica to do so.
Lake Xochimilco is the last remaining native habitat for the axolotl, a species of mole salamander endemic to Mexico. Until Lake Chalco was drained, the species had also been present there. Given Lake Xochimilco's present extensively compromised and reduced state, and the accelerating impact of Mexico City's urban growth, as of 2008 [update ...

Salamanders range in size from the minute salamanders, with a total length of 27 mm (1 + 1 ⁄ 8 in), including the tail, to the Chinese giant salamander which reaches 1.8 m (6 ft) and weighs up to 65 kg (145 lb).
Sirenidae, the sirens, are a family of neotenic aquatic salamanders. Family members have very small fore limbs and lack hind limbs altogether. [1] In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched together on the neck in both larval and adult
The Lake Pátzcuaro salamander (Ambystoma dumerilii) is endemic to Lake Patzcuaro, [1] and the axolotl salamander (Ambystoma mexicanum) is endemic to Valley of Mexico's wetlands. The wetlands support aquatic life. Some commercially-important fish depend on wetlands at one or more of their life stages.
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding.
