Nature Notes - Spencers Burrowing Frog

Image of Spencers Burrowing FrogYou might think that the dry environment of central Australia is an unsuitable place for frogs. But, in fact, there are quite a lot of frogs which are skilled drought dodgers and happily survive in the Australian deserts. They are generally small but absorb quite a lot of water and store it between their muscles and their skin. This gives them a round shape.

Features

Spencer’s Burrowing Frog (Limnodynastes spenceri) has half-webbed feet and smooth skin. The colour is variable but it has characteristic bars on its limbs.

Adaptations

Burrowing Frogs have digging implements on the side of their back feet. In dry times they dig down backwards into the sand in search of a moist spot where they can sleep until heavy rain awakens them from their slumber. A short burst of activity then follows. Up to the surface they climb, feed and reproduce before the water disappears.

Habitat

Desert rivers and gorges

Wild Status

Common

Diet

Spencer's Burrowing Frog is an opportunistic feeder, eating whatever insects are available. Termites are a common food item because of their own breeding response to the same moist conditions  which brings the frogs to the surface.

Home

Spencer's Burrowing Frogs lives in the sandy riverbeds of central Australia.

Life Span

Unknown

Size

30-45mm long

Reproduction

They breed at any time of year following heavy rain. The males call day and night from the water: a soft deep call somewhat similar to that of a laying hen.

Extra Fun Facts

A frog doesn’t chew its food but swallows it whole....with its eyes shut. Its big eyes bulge out of its head but also poke down into the mouth.  When the frog has food in its mouth, it pushes its eyes down several times to crush it. Then it swallows.

The name amphibian comes from two Greek words: amphi (meaning double) and bios (meaning life). It refers to the way these animals live in two worlds.

Frogs’ ears are like radios. They are tuned to the frequency of their own species while filtering out the calls of other species.

Frogs don’t drink. They absorb water directly through their skin.
