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. Reproduction Most frogs breed seasonally when conditions of temperature, day-length and moisture are right. Hatching of the tadpoles may take several days, followed by a period when the tadpole develops and finally changes into the adult frog, a process called metamorphosis. Frogs eat insects and overall must account for millions of insects daily. They also eat other small invertebrates.
