Frogs are a typical amphibian, and they also have outstanding characteristics of amphibians, which can move on land or in water. The same is true of frogs, but their places of activity are different at different ages. Larval frogs, that is, tadpoles just hatched from fertilized eggs, live in water. Frogs can live on land when they develop into young frogs and adult frogs. At this time, the frog's respiratory organs also changed. During tadpole period, they breathe with gills, while young frogs and adult frogs can breathe with lungs.

Therefore, frogs will drown, because they breathe through their lungs and can only breathe on land. Although frogs can move in water, they can't move for too long, because they can only breathe when they come out of water. If they stay in the water for a long time, they will be at risk of drowning or even drowning. Of course, frogs can't stay out of the water all the time, because they need wet skin to help their lungs breathe.

As mentioned above, since frogs breathe through their lungs, they can't stay in the water for a long time, otherwise they will be at risk of drowning. However, the larvae of frogs, that is, tadpoles, can be expected to stay in the water for a long time. At this time, their respiratory organs are gills, so it is no problem to breathe in the water. They do not need to breathe out of the water, and they cannot breathe out of the water. In fact, many amphibian larvae live in water, and their respiratory organs are gills, not just frog larvae.
