Frogs of Tasmania
|Brown Tree Frog|
A common and widespread species, up to 45 mm long. The brown tree frog (Litoria ewingi) is an agile climber, aided by the well-developed climbing discs on its fingers and toes. This species is often found in suburban gardens, where it is frequently found under logs and rocks.
Up to 30 mm long, this widespread species is by far the most abundant in the State. The common froglet (Crinia signifera) is found throughout agricultural areas, forests, sedgelands and moorlands, where it occurs beneath rocks, vegetation and leaf litter near ponds and swamps.
|Eastern Banjo Frog|
The eastern banjo frog (Limnodynastes dumerili) is a large and squat frog up to 65mm long. It is a capable burrower, digging with its hind legs and descending backwards into its burrow. This frog is found throughout most of eastern Tasmania and to the north of Macquarie Harbour on the west coast. A different subspecies occurs on King Island.
|Green and Gold Frog (T)|
The beautifully patterned green and gold frog is listed as Vulnerable on the Schedules of the Threatened Species Protection Act 1995, as population levels have declined markedly over the past ten years.
The latest 'addition' to the Tasmanian frog fauna came in 1992, when a new species, the moss froglet (Bryobatrachus nimbus) was discovered in the Hartz Mountains by David Ziegeler. To date, this species is only known from the south of south-western Tasmania.
The smooth froglet (Geocrinia laevis) is found throughout northern and central Tasmania including King Island, where it occurs in open forest, woodlands and buttongrass moorlands. It also occurs in south-west Victoria and south-east South Australia. It reaches a length of 33mm. The tadpoles take about six months to complete their development.
The southern toadlet (Pseudophryne semimarmorata) is found throughout the eastern half of Tasmania, where it prefers open forests and grasslands. It reaches a body length of 32 mm and has a warty, dark brown and olive green upper surface. The undersurface, however, is brilliantly patterned. Indeed, the southern toadlet is a close relative of the well-known and vividly patterned corroboree frog of the southern alps of mainland Australia.
|Spotted Marsh Frog|
The spotted marsh frog (Limnodynastes tasmaniensis) is found throughout the east and north east of Tasmania, where it occurs in farm dams, open woodlands, creeks and coastal wetlands. It also occurs throughout much of southeastern mainland Australia. It grows to a length of 45mm.
|Striped Marsh Frog|
The striped marsh frog (Limnodynastes peroni) is an attractive species, its dorsal (upper) surface patterned with a series of dark and light brown stripes. It grows to a length of 70mm. In Tasmania, it is an uncommon species, confined to the far north west and north east, as well as King Island. On the mainland, in contrast, it is widespread and common along the eastern seaboard. It is listed as Rare on Tasmania's Threatened Species Protection Act 1995.
Found only in Tasmania, the Tasmanian froglet (Crinia tasmaniensis) is common throughout much of the State. It is often found at high altitudes. It is always found near water, either temporary or permanent ponds or running water.
|Tasmanian Tree Frog|
Found only in Tasmania, the Tasmanian tree frog (Litoria burrowsae) is restricted to the west of the State. It is an attractive frog, with a green back, often patterned with brown. It can occur in rainforest and buttongrass plains. It can grow up to 60mm long.
