1) "Amphibians are totally dependent on water during their early stages of development. They must remain in moist habitats because they constantly lose water through their skin. Females lay their eggs directly in water or moist places where the larvae hatch and grow independently."

Amphibians eat aquatic (water living) and terrestrial insects, tadpoles, fish, frogs, and toads." Source: http://www.cheyennebottoms.net/b_w_marlist.html Without water, they could have problem finding something to eat. 3) "Amphibians were one of the first groups of animals to evolve from fish and develop adaptations to living on land, but they generally retained features that made them dependent on water such as the need to reproduce by laying eggs in water."

Its population is currently stable but its restricted range increases its vulnerability to threatening processes. It gives birth to one to six fully metamorphosed young on land, and unlike the majority of amphibians is not dependent on water." Source: http://www.globalamphibians.org/photos.htm
