L. peronii is found on the coast and ranges of Victoria, North South Wales, and eastern Queensland on the continent of Australia.

Biogeographic Regions: australian (Native )

The area of occurrence of the species is approximately 664300 km2.

Species is widespread and abundant and there is anecdotal evidence to suggest that the species may be increasing in numbers and extending its range in Queensland. It is often referred to as a weed species in Queensland.

Male L. peronii are approximately 65 mm in length, with females being slightly smaller. The dorsal surface of males and females is marked with a series of dark and light brown stripes, and there is frequently a pale mid dorsal stripe. The striped dorsal pattern breaks up laterally into a series of blotches. The ventral surface is white, except for the throat of the male, which is distinguished by a yellow wash and dark brown mottling. The snout is rather pointed and the iris is golden above and dark brown below. The toes are very long and not webbed, with a small inner metatarsal tubercle. The fingers are without webbing although breeding females have prominent flanges. The forearms show sexual dimorphism and they are bigger in males than females.

Limnodynastes peronii could be confused with L. salmini or L. tasmaniensis. The latter is much smaller (45 mm) and although the body shape is essentially the same, the dorsal pattern is spotted, not striped. L. salmini can be distinguished by the presence of pink-orange dorsal and lateral stripes.

Average length: 65 mm.

Sexual Dimorphism: male larger; sexes colored or patterned differently

• Terrestrial
• Freshwater

L. peronii is widespread and adaptable. L. peronii is usually found associated with permanent water throughout its range, in slow moving streams, swamps, marshes, damns, and ponds. It is especially common under debris on river flats. In suburban areas L. peronii commonly uses outdoor fish ponds as breeding sites. The striped marsh frog also appears tolerant of polluted water.

Aquatic Biomes: lakes and ponds

Juvenile L. peronii are herbivores that feed on aquatic flora. However, once the striped marsh frog matures, its food habits change. Mature L. peronii are carnivores that tend to feed on insects and other small invertebrates.

Breeding occurs form August until March. The female deposits 700 to 1,000 small, unpigmented eggs in a foam mass entangled in vegetation at the edge of a slow moving river or pond. An exception occurs in southern Australia. In the lower southeast of South Australia females lack finger flanges and do not produce a foam nest. The tadpoles reach 65 mm in length and are pale brown with the adult dorsal pattern becoming apparent as the tadpole is developing forelimbs.

Breeding season: Breeding occurs from August to March.

Range number of offspring: 700 to 1,000.

Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); oviparous

This is one of the most common frogs of eastern Australia. There are currently no problems with population numbers and no IUCN warning listings. However, if deforestation and destruction of aquatic habitat occur, L. peronii could face a drastic reduction in population numbers.

IUCN Red List of Threatened Species: least concern

Breeding occurs from August to March. Males call by day hidden in thick vegetation, forest debris or overhanging ledges. At night they call from the water floating in concealed sites. Females lay 700 - 1000 eggs in a foam nest tangled in vegetation (reeds and rushes) at the water's edge.

These frogs currently have no commercial economic value for humans. However, the Brown Striped Marsh Frog helps humans by feeding on insects.
