Are frog's eyes special? Why can't you see what else is in front of you?

Frogs have really special eyes. It can't see clearly what is still in front of it because the frog's eyes have no movable eyelids, because when the object is still, the frog can't notice its existence, and only the moving object can attract the frog's attention. Moreover, although the frog's eyes are big, they are actually nearsighted, so only what moves in front of him can attract the frog's attention. Even if it moves too far, it can't see clearly.

Frog's predation process Although frogs need to move objects when they prey, they also have strong resolution. If there are many kinds of bugs flying around in front of the frog, the frog's eyes can quickly distinguish the creatures they like to eat. It can quickly locate and analyze these small moving animals through different images. Once the analysis is completed, the frog's eyes will only stare at its own target, and other moving small animals are not attractive to frogs.

Then the frog can quickly judge the position of this creature, and then attack the food quickly and accurately with the frog's tongue. So when flies and other animals appear at the same time, you will find that frogs can always catch flies at the first time, because they may only have their favorite flies in their eyes.

Frog's eyes Frog's eyes can't shake and tremble, and its eyeballs are prominent. This eye structure also makes the frog nearsighted from birth, so it can't respond to static objects around it. Only when animals are moving can they form a picture in their eyes, otherwise, a static object will have no picture in their eyes, just like there is no picture.

Therefore, even if there are many flies around the frog, as long as it doesn't fly, the frog doesn't know that there is delicious food around it. As long as they fly, frogs can find them at once. Therefore, if you don't walk around the frog, it can't actually notice it.
