There are many different species of frog in austrailia, and just as many answers to this question. Frog development depends on which kind of frog we are discussing, not on which continent the animal is from.
in till the tadpoles hatch. then when they all hatch the mother and father leave them
As long as they are the same species, yes.
Frogs and their tadpoles are unable to exist in saltwater.
No. Tadpoles are newly-hatched frogs and come from their eggs.
tadpoles will eat algae or dead skin off fallen members where when the grow tadpoles become more carnivores feeding on less algae and more bugs once they get the long tongue
1 minute
3 weeks
A week or two depending on how long ago it hatched. It always depends on the species. A tree frog took about 5 weeks (a little over a month), and a bullfrog tadpole took 2 years! Usually, tree frogs and smaller frogs take less time while massive frogs such as bullfrogs, pacman frogs, and others take years.
It can be as short as a couple months (Cane Toad) or as long as 1 to 3 years (Bullfrogs.)
Some tadpoles take longer than others to turn into frogs based on the species. Under unfavorable condition, some tadpoles take up to two years to transform. However, generally it takes tadpoles 2-3 months to become frogs.
Frogs don't sit on their eggs. Their eggs (frogspawn) are laid in bulk and they float in the water and hatch by themselves. The young frogs emerge as tadpoles. Between three and six weeks later they start growing legs and their tails disappear, and they gradually become frogs.
They will eat anything that fits in their mouth as long as it is not poisonous or harmful.
