Eastern banjo frog, Limnodynastes dumerili
Found throughout most of eastern Tasmania and to the north of Macquarie Harbour on the west coast, this species is a large and squat frog up to 65 mm long. It is a capable burrower, digging with its hind legs and descending backwards into its burrow.
It occurs in dams and lagoons in agricultural land and in coastal wetlands. Males have been known to migrate up to one kilometre to reach breeding sites. The female lays up to 3 900 eggs. Tadpoles take anywhere between four and fifteen months to complete development. This variation in development time is the due to water temperature -- metamorphosis is slower in colder conditions
Its call is a remarkable banjo-like 'bong--bong' heard in the spring and summer.
