Black mountain boulder frog — a small dark frog that lives only among large rocks on one mountain in Australia. It has direct development: fully formed froglets emerge from eggs without a tadpole aquatic stage.
This frog has a very limited range—it is found only on one mountain among the rocks. It is important for nature as an example of direct development in amphibians and part of a unique ecosystem where it controls insect populations.
Immature form that undergoes metamorphosis before adulthood.
