Amphibians are master predators. Just take a look at this Tomato Frog (Dyscophus guineti) grab these crickets! What would we do without these animals taking care of insects for us? Amphibians are part of a chain that keep everything balanced and in check. Here you can see that amazingly long and sticky tongue grab the cricket. Also, if you notice, the eyes close as the frog swallows it’s prey. Some evidence suggests that the large bulging eyes of some frogs actually aid in pushing food items down the throat from the inside of the mouth. The frog is at no risk of injury to it’s eyes from the prey item either. This is not true for all frogs, the African clawed frog comes to mind.
