Frogs other names of toads, have rough and freckled or frayed skin, are often dry, and the hind legs are often short, so most frogs / toads are not good at jumping away.
Frogs and frogs start their life as eggs that are placed on the mother's water, in a foam nest, or in other wet places. Several types of mountain frogs kept their eggs among the wet moss in the trees. While other types of forest toads leave their eggs on the back of a damp frog male, which will always keep and carry them until they hatch even into small frogs. Once spawn frogs can produce 5000-20000 eggs, depending on the quality of the parent and lasted three times a year .

The frogs and frog eggs hatch into tadpoles or tadpoles, which are bodied like fat fish, breathe with gills and for some time live in water. Slowly the legs will grow back, which is then followed by the growth of the forefoot, the disappearance of the tail and the replacement of the gills with the lungs. After its time, this tadpole will leap ashore as a frog or small frog.
Frogs and frogs mate at certain times, for example at the time of the dead month or at the time of the rain. At that time the male frogs will be beeping to call the females, from the edge or the middle of the waters.
Some species, such as the moored frog (Fejervarya limnocharis) and the bellyung aka bellyung (Kaloula baleata), often form a 'singing group', in which several male animals gather nearby and sound together. The tough frog's sound is generated by a voice pouch that lies around its neck, which will bulge big when used. Frog fertilization is done outside the body.
Male frogs will cling to the female back and hug the armpit of the female from behind. While swimming in the water, the hind legs of a male toad will massage the female toad's stomach and stimulate the release of the egg. At the same time a male frog will release its sperm into the water, so that it can fertilize the eggs that the females issue.-
