Why do frogs croak at night?

Frogs spend most of their time quietly hiding in the dark, not making any sound, and not coming into contact with other frogs. But during the breeding season, they will migrate into the water in groups for reproductive activities, making calls. Some species are very active day and night, and are especially excited on rainy days. Generally speaking, it is mainly male frogs that call, and female frogs rarely call. Male frogs will make different calls depending on the occasion, such as calls to establish a territory to warn other male frogs not to approach, encounter calls when driving away other male frogs or fighting, courtship calls to attract females, mating calls after contact with females, release calls when being held by other male frogs or other species of frogs, and emergency "chi" calls for help when being caught by natural enemies.

Why do frogs in different places have different colors?

After natural selection, the body colors of frogs in different environments are different.

The frog's back is green, smooth, soft, and has patterns, and its belly is white. It can hide in the grass, making it easier to catch pests, and it can also protect itself.
