What role do the frog’s eyes play in the feeding process?

An amazing discovery has been made regarding the eyes of a frog. It turns out that her organs of vision, along with the tongue, take part in the process of swallowing.

After the insect has adhered to the sticky tongue of the frog, the prey is pushed down the throat. Thanks to a special thinnest film that separates the eyes from the mouth, the frog delivers food inside the body. Therefore, closing the frog’s eyes when swallowing is not associated with the enjoyment of tasty food, but is a convenient way to draw in prey.
