Gastrotheca

Japanese: Gastrotheca

...Many tree frogs lay eggs in small puddles. In tropical America, some lay large gelatinous egg masses on the leaves of epiphytes, while others lay eggs in the small amount of water that accumulates between the leaves, and the larvae feed on the eggs and larvae of other frogs. There are also the 3cm-long Gastrotheca frogs, which raise their larvae in a pouch on their back, the Goeldi frog Fritziana goeldii (5cm long), which protects its eggs by carrying them on its back, and the Kajiya frog Hyla faber (10cm long), which builds mud nests near water and lays eggs. In recent years, an active peptide that has been used as a diagnostic drug for the digestive system in Japan has been extracted and purified from the skin of the Australian white tree frog Litoria caerulea (10cm long). ...

From [Frog]

…The latter species are rare, but unusual methods of protecting eggs and larvae are found across lineages. In the mid-summer frogs Alytes and the Seychelles burrowing frogs Sooglossus , parents protect the eggs and larvae by attaching them to their bodies, while in the wolf frogs and the pompano frogs Gastrotheca , females nurse a small number of large eggs in a nursery on their backs until metamorphosis is complete. In the Darwin's frog Rhinoderma darwinii , the male is in charge of nursing the young until the vocal pouch is filled with them, but in the Australian black wolf frog Rheobatrachus silus , the female nurses the larvae in her stomach. …

…アマガエル類には小さな水たまりでも産卵するものが多く，熱帯アメリカでは着生植物の葉に大粒のゼリー状卵塊を産むものや，葉の間にたまったわずかな水に産卵し，幼生は他のカエルの卵や幼生を餌とするものもある。また背中の育児袋で幼生を育てる体長3cmほどのフクロアマガエル類Gastrothecaや，卵を背負って守るゲルジアマガエルFritziana goeldii(体長5cm)もあり，水辺に泥の巣をつくって産卵するカジヤアマガエルHyla faber(体長10cm)もいる。近年，日本でも消化器系の診断薬として用いられる活性ペプチドは，オーストラリア産ホワイトアマガエルLitoria caerulea(体長10cm)の皮膚から抽出純化されたものである。…

…後者の種類は少ないが，卵や幼生の保護手段に風変りなものが系統と関係なく見られる。サンバガエル類Alytesやセーシェルコオイガエル類Sooglossusなどでは，親が卵や幼生を体に付着させて守るが，コモリガエル類やフクロアマガエル類Gastrothecaでは雌が背中の育児室で，大粒の少数卵を変態終了まで育てる。ダーウィンハナガエルRhinoderma darwiniiでは雄が育児を担当し，鳴囊内が子ガエルでいっぱいになるまでめんどうをみるが，オーストラリア産イブクロコモリガエルRheobatrachus silusは，雌が胃袋の中で幼生を育てる。…
