Question

Can frogs turn themselves insideout?

Answer 1

The frog may actually throw up its entire stomach. The total stomach vomiting mechanism in toads has the same result as emptying a bag by pushing its bottom up through the top. The stomach literally turns inside out, and dangles from the toad’s mouth.

Once in the inside-out position, the unwanted contents of the toad’s stomach are likely to drop away. To be sure this has occurred, the toad has a secondary reflex associated with stomach vomiting.
