Giving birth through your mouth maybe above and beyond the call to motherhood for most animals , but two species of frogs were discovered in Australia in the 1970s. Have you seen them anywhere?
Possibly now extinct. When scientists watched them, thry saw how females swallowed and incubated their eggs . The stomach acids of the average animal would dissolve these eggs as food, but mama frogs stomach digestive juices turn off production of hydrochloric acid in the stomach, until the tadpoles became baby frogs make their way out mama’s mouth and hopped out into the world.
Scientists want to find these frogs again to study how they can turn off the stomach acids in hopes it might give scientists a ways to help people with stomach ulcers.
