How do gastric brooding frogs reproduce?
Reproduction. What makes these frogs unique among all frog species is their form of parental care. Following external fertilization by the male, the female would take the eggs or embryos into her mouth and swallow them.
When did the gastric brooding frog become extinct?
The Southern Gastric-Brooding Frog (Rheobatrachus silus) was an aquatic frog that lived in south-east Australia. In 2002, the International Union for Conservation of Nature Red List declared the frog extinct, although no wild specimens had been reported since 1981.
What do gastric-brooding frogs eat?
insects
Southern gastric-brooding frogs have been observed feeding on insects from the land and water. In aquarium situations Lepidoptera, Diptera and Neuroptera were eaten. Being a largely aquatic species the southern gastric-brooding frog was never recorded more than 4 m (13 ft) from water.
Why did gastric-brooding frogs go extinct?
The cause for the gastric-brooding frogs’ extinction is speculated to be due to human introduction of pathogenic fungi into their native range. Populations of southern gastric-brooding frogs were present in logged catchments between 1972 and 1979.
Why should we bring back extinct species?
Studies suggest that if large grazers were returned to the far north, biodiversity would increase again. It could be the same for other de-extinct animals, too. De-extinction provides a means to enhance biodiversity and help restore the health of ailing ecosystems.

Is every frog poisonous?
All frogs have poison glands in their skin. In most cases, these toxins aren’t strong enough to discourage predators. (Witness the fact that frogs are a basic food for many animals, including birds, rodents, fish, foxes, and wolves–and people!)
How did gastric brooding frog evolve?
How many gastric brooding frogs are there?
two species
The genus consisted of only two species, both of which became extinct in the mid-1980s. The genus is unique because it contains the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother.
