Why does a frog bite a small lump of cotton and not let go, resulting in being caught?

Many rural people have the experience of fishing frogs, especially when they were children, fishing for frogs is a very fun thing, because fishing for frogs is much easier than fishing, fishing frogs does not need a hook at all, only a small ball of cotton can be used, of course, with other things, the size is about the size of a sugar cube, before fishing for frogs, tie cotton to a line, the line is tied to one end of a long stick, and then pick up the stick, pick up the cotton on the rope, go to the pond to find a frog, dangle in front of it, without a few strokes, The frog will jump up and swallow the cotton into its mouth, and then you will lift it, and the frog will swing up and down without letting go at all.

Although the frog is small, its bite force is not small, and what it bites requires several times its own body weight to pull away, so even if you throw the rope up with a stick, the frog will not fall.

Maybe now the children in the countryside are rarely fishing for frogs, because most of them play with mobile phones, the game is more fun than fishing frogs, in this modern school to educate children to protect small animals, frogs are beneficial insects, so the people who have fished frogs may be older, people who have fished frogs know that the frog is in their hands, and it is not easy to pull it down, because its mouth is still very tight, indicating that its bite force is indeed very large, but there is a clever way to loosen it, that is, to pinch both ends of its mouthWith a little force, it will loosen up.

Many people may be curious, including frog fishers, why can they catch frogs with a ball of cotton? In fact, this is related to the frog's predatory habits, the frog's diet is basically insects that can fly and run, so the frog's eyes usually only react to moving things, when you use a ball of cotton to dangle in front of the frog's eyes, the frog can not judge whether this thing can be eaten, only think that it is also grasshoppers, moths and other insects, so it jumps up, opens its mouth and swallows the cotton.

Cotton is obviously inedible, so why doesn't the frog spit it out after swallowing it in its stomach? Doesn't it tell that something can't be eaten? In fact, this is a problem worth studying, at present, it is usually believed that frogs do not have the habit of spitting out, so they don't know how to spit out, I think this is wrong, a creature that has lasted for hundreds of millions of years, it is impossible not to know what can and cannot eat!

Another reason is that some people think that frogs belong to amphibians, IQ is relatively low, and they refuse to let go when they have food, but in fact, monkeys also have such a phenomenon, monkeys belong to primates, and they are animals with relatively high IQ, but once the monkeys grab the food, they are usually reluctant to let go when they encounter danger, so it is said that when Indians catch monkeys, they put a walnut in this transparent box, and this box only has a small hole on the top, and this small hole only allows the monkey's arm to stick in. If you catch the walnut, you can't get out, so when the monkey steals the walnut, the person walks over and catches the monkey very easily, because the monkey won't put the walnut down and pull it out of the box, so the reason why the frog doesn't let go of its mouth may be a reason for this phenomenon.

Because he treats cotton as food, the frog's IQ is relatively low, and it cannot tell the difference between cotton and insects.

The cotton must have been tied to the top of the frog that frogs are more interested in eating, such as pests and the like.

I think the frog must have thought that cotton was a delicious thing, so he never let go.

This is because the frog is an animal that once it bites something, it thinks it is food, and then it never lets go until it swallows it. It can only see things that move, so when the cotton moves in front of it, it bites, so it can catch it.

I think this is too greedy, and I have been reluctant to let go, so everyone can't be greedy.

This is related to the frog's predatory habits, because in the eyes of the frog, it usually only reacts to moving things, and when you dangle the cotton in front of the frog's eyes, it can't judge whether the thing can be eaten or not, so it will bite the cotton and not let go, resulting in being caught.
