Frogs and snakes are both animals that can be seen in daily life and are very familiar animals. Frogs and snakes can be said to be two incompatible animals. Usually, frogs are the weaker side, their size is relatively small, and in most cases they are the eaten side, while snakes are the stronger side. In this sense, snakes can be said to be the natural enemies of frogs. However, in reality, there are some exceptions, and frogs sometimes eat snakes in turn.

Of course, this is rare. Generally speaking, frogs that eat snakes are relatively large in size, such as bullfrogs, which are regarded as the relatively large frog species, and they will eat snakes. However, generally speaking, the snakes they eat are relatively small and thin, so that the snakes will be eaten by frogs. Even very large frogs are afraid to provoke when they meet big snakes. Once they are careless, they are easily eaten by snakes. In fact, in addition to these relatively large frogs, other frogs eat some very small insects, and do not eat snakes. Therefore, relatively speaking, snakes eat frogs more, while frogs eat snakes less.

Voles are relatively large animals for frogs, so generally speaking frogs can't eat voles. However, some frogs are relatively large, such as bullfrogs mentioned above, which can eat snakes. Such frogs can eat voles. Except for these large frogs, other frogs generally have no ability to eat voles. On the contrary, voles can easily eat frogs, and voles can also be said to be one of the natural enemies of frogs.
