Note the animals' different sizes. Obtain photographs, distribution maps, descriptions, and audio files. There are over 200 species of frog occurring in Australia. Frogs belong to the Class Amphibia, and all are reliant on moisture to breathe, reproduce and generally survive and thrive. Nocturnal life is one way of minimising the risk of drying out, for it is the coolest part of the day.
Most frogs are active at night.
Despite this drawback of a dependence on water, frogs have evolved and diversified in form to occupy a variety of habitats, from rainforests to deserts, from rock faces to subterranean burrows, from free water to sphagnum moss bogs - frogs are found in a surprising number of different spots. Their skin is very rough, and has several large dark blotches on the back region. Gray Treefrogs will usually have a light colored spot with a dark edge under each eye and enlarged toe pads. This frog makes a hearty trilling sound. This species has also been introduced into Canada, various parts of the West, and Hawaii.
