The pouched frog (Assa darlingtoni), or hip pocket frog,[2] is a small, terrestrial frog found in rainforests in mountain areas of south-eastern Queensland and northern New South Wales, Australia. It is one of two species within the genus Assa, the other being Assa wollumbin[3] and is part of the family Myobatrachidae.
It is a small frog about 2.5 cm long, red-brown in colour, with some individuals having reverse V shaped patches and/or with light brown dots randomly on their backs. Most specimens have a darker brown stripe that runs from the nostril through the eye down the side of the body. A skin fold is present on either side of the frog running from its eye to its hip. Its hands and feet are completely free of webbing and discs, but the tips of the fingers and toes are swollen. The eye is gold with brown flecks and when the pupil is constricted it is horizontal. There is a 'pocket' on its hip where the frog's tadpoles travel to after hatching.
The hip-pocket frog living in Australia has been affected by the forest fires of Australia. The fires is not suitable for the pocket frog and is now classified as endangered and vulnerable. Although the frog has a unique reproductive method where the male carries the developing tadpoles in the pouch by its hips until metamorphosis. The male species has a greater parental care in the development of the new organisms.
This frog hides under logs, rocks, and leaf litter in rainforests and adjacent wet sclerophyll forests. It may call through the day but calling is most intense during dawn and dusk. Its call is a very quiet eh-eh-eh-eh-eh-eh, usually six to ten notes. This frog crawls rather than hops. Females are believed to first start breeding between 2 and 3 years and a single female may produce 1–50 eggs a year. Eggs are laid on the land (under decomposing logs, rock or leaf litter) as the tadpoles do not need water for metamorphosis. Breeding takes place during spring and summer. Both male and female frogs guard the nest of eggs and the male carries the tadpoles in the pouch once they have hatched. The tadpoles will reside in the pouch until they have morphed.
This species formerly experienced declines; however, it has recovered.
The second species in the genus, Assa wollumbin, is smaller and reaches only 1.6 cm in leghth. Assa darlingtoni may be confused with some species of Philoria and Crinia, which live in the same area. Philoria species show thicker arms than Assa darlingtoni, Crinia species have a rougher belly texture.

Assa darlingtoni, unique représentant du genre Assa, est une espèce d'amphibiens de la famille des Myobatrachidae[1].
Cette espèce est endémique de l'Est de l'Australie[1],[2]. Elle se rencontre dans le nord-est de la Nouvelle-Galles du Sud et dans le Sud-Est du Queensland.
L'holotype de Assa darlingtoni[3], une femelle mature, mesure 19 mm.
Cette espèce est nommée en l'honneur de Philip Jackson Darlington Jr. (1904–1983)[3]. Le genre Assa, du latin assa, « étuve, nourrice sèche », a été choisi en référence au fait que les jeunes sont souvent transportés mais ne sont pas nourris[4].
Assa darlingtoni, unique représentant du genre Assa, est une espèce d'amphibiens de la famille des Myobatrachidae.
Assa darlingtoni is een kikker uit de familie Australische fluitkikkers (Myobatrachidae).[2] De soort werd voor het eerst wetenschappelijk beschreven door Arthur Loveridge in 1933. Oorspronkelijk werd de wetenschappelijke naam Crinia darlingtoni gebruikt. Het is de enige soort uit het geslacht Assa.
De kikker is endemisch in Australië.[3] De kikker leeft op de bodem van vrij vochtige bossen in de strooisellaag tussen de bladeren.
De voortplanting is bijzonder; de eitjes worden op de bodem afgezet en als ze uitkomen worden de kikkervisjes opgevangen door het mannetje, die ze in buidel-achtige flappen op de heupen meedraagt tot ze gemetamorfoseerd zijn tot kleine kikkertjes. Een dergelijke gespecialiseerde vorm van broedzorg is alleen bekend van deze kikker.
Assa darlingtoni é uma pequena rã terrestre encontrada em florestas tropicais em zonas montanhosas do Sudeste de Queensland e norte de Nova Gales do Sul, Austrália. É a única espécie do género Assa e é parte da família Myobatrachidae.
É uma pequena rã com cerca de 2,5 cm de comprimento, vermelho-acastanhado na cor, com alguns indivíduos tendo manchas em forma de V invertido e/ou pontos castanho-claro distribuídos aleatoriamente nas suas costas. A maioria dos espécimes têm uma faixa marrom escura que é executado a partir da narina através do olho para baixo ao lado do corpo. Uma dobra de pele está presente em ambos os lados da rã compreendido entre seus olhos e seu quadril. Suas mãos e os pés são completamente livres de membranas interdigitais e discos, mas as pontas dos dedos e dedos dos pés são inchadas. O olho é ouro com mancha marrom e quando o aluno é formado é horizontal. Há uma 'bolsa' no seu quadril onde os girinos da rã viajam após a eclosão.
Este sapo esconde-se sob troncos, rochas e resíduos de folhas em florestas tropicais e florestas esclerófilas húmidas adjacentes. Ele pode chamar durante o dia, mas a chamada é mais intensa durante o amanhecer e anoitecer. Seu apelo é um eh-eh-eh-eh-eh-eh muito tranquilo, geralmente de seis a dez notas. Este sapo rasteja em vez de saltar. Acredita-se que as fêmeas começam a reproduzir-se com entre 2 a 3 anos e que uma única fêmea produz 1-50 ovos por ano. Ovos são postos na terra (sob troncos em decomposição, rochas ou detritos de folhas) uma vez que os girinos não precisam de água para a metamorfose. Reprodução ocorre durante a Primavera e Verão. Rãs machos e fêmeas protegem o ninho de ovos e o macho carrega os girinos na bolsa depois de eles eclodirem. Os girinos residirou na bolsa até se transformarem.
Esta espécie anteriormente experimentou declínio, porém recuperou.
Embora este sapo seja a única espécie no seu género, ele pode ser confundido com Philoria loveridgei. Philoria loveridgei tem dobras da pele angular na superfície dorsal e braços mais grossos do que Assa darlingtoni.

Ареал
Сумчатая жаба[1] (лат. Assa darlingtoni) — вид бесхвостых земноводных из семейства австралийских жаб (Myobatrachidae). Видовое название дано в честь американского зоолога Филипа Джексона Дарлингтона (1904—1983)[2]. Единственный вид рода Assa.
Лягушки небольшого размера, не более 2,5 сантиметров в длину. Окраска красновато-коричневая с V-образными пятнами и светло-коричневыми точками на спине. Большинство особей имеют тёмные коричневые полосы, идущие от ноздрей. На бёдрах у лягушек с обеих сторон есть особые кожные складки, образующие подобие сумки.
Южные районы австралийского штата Квинсленд и северные районы Нового Южного Уэльса.
Животное обитает во влажных лесах, где прячется под корнями, камнями, опавшими листьями. Ведёт преимущественно ночной образ жизни. Передвигаются скорее ползком, чем прыжками.
В брачный период самцы издают тихие, но мелодичные звуки. Фертильный возраст у самок наступает в 2 — 3 года, одна женская особь способна произвести до 50 яиц. Икринки откладываются под листья или разлагающиеся древесные стволы, так как головастики не нуждаются в водоёмах для своего развития. Гнездо охраняют и самец, и самка, от после выхода головастиков из икринок самец забирает их в «сумку» на бедре, где детёныши проходят дальнейшее развитие. Там головастики находятся до метаморфоза.
