The turtle frog of Western Australia uses its short but muscular front arms — rather than back legs like most frogs do — to dig more than a metre (>3.3 ft) beneath the soil. Adapted to semi-arid habitats far from water, its tadpoles develop inside their eggs and hatch as tiny frogs.

The moaning frog is named for its call, which sounds like a slow and drawn-out moan. This burrowing frog is native to southwestern Western Australia, where its calls can keep people up at night — it's recommended to gently flood the frog's burrow each night until the moaning male moves on.
