( Australian Government Department of the Environment, Water, Heritage and the Arts) Researchers are trying hard to bring one of the world's weirdest, and undoubtedly coolest, frogs back to life. The Gastric-brooding frog became extinct in the mid-1980's. It was native to a small portion of Queensland Australia and, here's what makes it so interesting, it gave birth through its mouth. The gastric-brooding frog is the only known frog to give birth through its mouth. According to researchers at the University of South Wales, the frog lays eggs but then swallows them. The eggs are coated in a substance called prostaglandin which causes the frog to stop producing gastric acid in its stomach so the eggs will be safe in her stomach.
