In order to ensure the safety of the next generation and prolong life, various creatures take great pains to protect their offspring. One of the most famous creatures is called the stomach frog.
Stomach frogs, as the name suggests, are frogs that nurture children in the stomach. When the eggs are fertilized in vitro, the female frog will swallow the fertilized eggs into the stomach and nurture them in the stomach.

You may wonder, aren't those fertilized eggs that are swallowed in the stomach not digested? In fact, the substance surrounding the fertilized egg can inhibit the secretion of stomach acid to prevent it from being digested. Before the fertilized egg hatches, the mother frog will not eat or drink. Once the fertilized egg hatches, the baby frog will jump out of the mother frog's mouth.
Discovered in 1972, the stomach brooding frog lives in the rainforests of eastern Australia, with large eyes and slender bodies, and is a cute little creature. However, it is very regrettable that due to the influence of human activities and other reasons, the stomach breeding frog has died out around 1983.
