Life History, Abundance, Activity, and Special Behaviors ( Inglês )

fornecido por AmphibiaWeb articles
Associated with large expanses of water upon the flood plains and savannah woodlands of northern Australia. It commonly occurs around the edges of permanent water or areas where the water remains for several months during the wet season. During the day it may be seen basking on ground beside water. In the dry season it hides in cracks and crevices in the soil.Breeds during the summer wet season from February to March. Males have been observed calling whilst floating in water.

Dahl's aquatic frog ( Inglês )

fornecido por wikipedia EN

Dahl's aquatic frog (Ranoidea dahlii) is a species of frog in the subfamily Pelodryadinae, endemic to Australia. Its natural habitats are dry savanna, subtropical or tropical dry lowland grassland, freshwater lakes, intermittent freshwater lakes, freshwater marshes, and intermittent freshwater marshes.

Dahl's aquatic frog was once thought to be able to consume the eggs, tadpoles, and young of the invasive and venomous cane toad with no apparent ill effect, but this observation was based on a handful of captive survivals. Adults regurgitate the young toads, and avoid eating them in the future, or rarely swallow them; in this case, about half the adults die. These frogs do not appear to have an elevated resistance to bufotoxins compared to other Australian hylid frogs, and avoid these toads if they survive their first toad meal.

Litoria dahlii ( Espanhol; Castelhano )

fornecido por wikipedia ES

La rana acuática de Dahl (Litoria dahlii) es una especie de anfibio anuro de la familia Pelodryadidae.[2]

Es endémica del norte de Australia.[3]​ Su hábitat natural son las sabanas secas, subtropicales y tropicales de tierras bajas de pastizales secos, lagos de agua dulce, lagos de agua dulce intermitentes, pantanos de agua dulce, y los pantanos de agua dulce intermitentes.

Entre los rasgos más singulares de la rana acuática de Dahl es su capacidad de consumir huevos, larvas y pequeños sapos de caña invasoras y venenosas, sin efectos adversos aparentes por lo que es quizás, la única criatura de Australia natal con una inmunidad natural al veneno del sapo de caña. Aunque estas observaciones fueron hechas en cautiverio, los científicos no encuentran razón para no creer que dicho comportamiento sucede también en estado salvaje.[3]
