They are not found in the sea with the exception of one or two frogs that live in brackish water in mangrove swamps; [34] the Anderson's salamander meanwhile occurs in brackish or salt water lakes. [35] On land, amphibians are restricted to moist habitats because of the need to keep their skin damp. [31]
Adult frogs live in fresh water and on dry land; some species are adapted for living underground or in trees. Frogs typically lay their eggs in the water. The eggs hatch into aquatic larvae called tadpoles that have tails and internal gills. They have highly specialised rasping mouth parts suitable for herbivorous, omnivorous or planktivorous ...
Amphibians, which include frogs, toads, salamanders, and caecilians, are a group that predominately exist in freshwater habitats. Amphibians are exotherms that possess thing skin, meaning that they rely on water to remain hydrated. [ 13 ]
It lives an entirely aquatic lifestyle in parts of North America in lakes, rivers, and ponds. It goes through paedomorphosis and retains its external gills . [ 4 ] Because skin and lung respiration alone is not sufficient for gas exchange, the common mudpuppy must rely on external gills as its primary means of gas exchange. [ 5 ]
Lake Xochimilco is not a large body of water, but rather a small series of artificial channels, small lakes, and temporary wetlands. Lake Xochimilco is the only native habitat left for the axolotl. Lake Xochimilco has poor water quality, caused by the region's aquaculture and agriculture demands.

The Sierra Nevada Yellow-legged frogs were almost wiped out of Yosemite National Park. But these scientists mounted a wildlife comeback. 'The lakes are alive again': These frogs are back from near ...
All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.
