Frogs eat their prey, such as small insects, snakes, and birds, without chewing. Since they use their teeth to hold their prey in place before devouring it, frogs blink while they eat in order to aid the swallowing process. When frogs close their eyes, they are actually pushing their eyeballs down into their sockets to facilitate food moving more quickly down toward the esophagus. Although frogs can physically consume food without blinking, it can take twice as many swallows than if they use their eye sockets to assist in the process.
