Northern Gastric Brooding Frog

Also known as Eungella Gastric-Brooding Frog

Females of this remarkable Australian amphibian swallowed fertilized eggs, suppressed stomach acid production via chemical cues, and incubated their young in the stomach before giving birth through the mouth. Restricted entirely to pristine, tumbling streams in Queensland's cool Eungella rainforest, individuals sheltered beneath submerged granite boulders during the day. Discovered in 1984, the species vanished mere months later, falling victim to the catastrophic amphibian chytrid fungus before scientists could fully understand its biology.
