The Stuttering Frog (Mixophyes balbus) has a call like a kookaburra in a hurry: ‘kook kook kook kra-a-ak… kruk… kruk’. Quite a chunky frog (up to 8cm in length), it is also known as the Southern Barred Frog because of the stripes on its arms and legs. Stuttering Frogs live near fast-flowing streams in the wet forests along the east coast of Australia, from north-eastern Victoria to southern Queensland. They are found at a range of altitudes, from 20m to more than 1400m above sea level. Stuttering Frogs have only been found in Victoria on three occasions, and may now be extinct in this state.
Many populations of Stuttering Frogs have disappeared. Possible causes include:
Zoos Victoria is working to change the fate of threatened species and is committed to Fighting Extinction – we will ensure that no more Victorian terrestrial vertebrate species become extinct.
Recent genetic studies indicate that there are two distinct forms of Stuttering Frog. Zoos Victoria is focusing on the southern form and will continue to breed this form in captivity to maintain an insurance population. We are also developing a plan to collect more tadpoles to increase the genetic diversity of the captive population.
