Why do frogs croak after rain?

Green frogs don't like dry environment. Most of them live near the water or in places with high humidity. There are many fine cells secreting body fluids on the skin surface of the green frog, which keep the skin moist and healthy. Have you noticed that the green frog will keep barking on rainy days? Why is this? Because of the high air humidity, the green frog felt very comfortable, so he shouted happily! Do you know anything else? Only male green frogs can bark! In addition, during the breeding season, they will keep barking.
