I wonder why….

I wonder why…
Why do frogs blink when the swallow? Well, since frogs don’t have teeth they use two eye bulges on the tops of their mouths to swallow. When the frog catches food it rolls its eyes to the back of its head which forces its food to the back of its mouth where its cavities of located.This movement helps get the insect down the frog’s throat easily. Also since the frog’s tongue is designed to catch the prey rather than help swallow the bug this technique isn’t a bad one.
