Frogs eventually eat small insects. The reason for using the word “eventually” is because tadpoles only eat leaf and algae. When they finally develop and mature, they then start to east insects and other small preys – spiders, small fish, worm and snails. Since frogs do not have teeth just like snakes, they consume their preys by swallowing it entirely since they cannot chew anything.
They use their sticky tongue to catch their prey and it only takes less than a second for their tongue to roll out and catch whatever insects they want to eat. Another fun fact about frogs is that they also use their eyes to help them swallow up their prey. They sink their eyes through their skill so that they can force down the food to their throat.
