One of the most surprising curiosities about vomiting, concerns some species of frog up close. These animals, when they feel the need to empty their stomach, instead of expelling gastric contents like we humans, adopt a more drastic solution.
The frog, in fact, is able to let the entire stomach escape from the mouth, only to swallow it with the help of the right front paw, to make it return to its place.
This peculiarity is due to the fact that the frog has a sufficiently long and mobile esophagus, while the stomach tends to be anchored with shorter fibers on the right side of the body, so when it is "vomited" it protrudes slightly from the right side of the mouth.
