Frogs are a kind of amphibians. As amphibians, they naturally conform to the basic characteristics of amphibians, that is, they can move in water or on land. Frogs naturally swim when they are young, that is, when they are tadpoles, because they can only live in water at this time, and can't come to land yet. When frogs are adults, that is, when they are adult frogs, they can move on land. At this time, they can also move in water. They can swim. Of course, the way they swim is very different from that of fish.

In fact, adult frogs can't stay on dry land all the time, because this will make their skin very dry, and their breathing will be affected to some extent. They also need to move in the water regularly, so they can swim naturally. Frogs sometimes go to the water, and sometimes they move around the grass.

As mentioned above, frogs can swim, and so can fish in water, but frogs and fish swim in very different ways. There is a swim bladder in the body structure of fish. By controlling this structure, fish can control their rise and fall in water. But frogs don't have this special structure. They can only swim by their legs. When frogs move through the water, they use their legs to climb into the water, thus generating corresponding strength to make themselves move in the water.
