Frog's complementary ability is very high in animal kingdom. It always likes to live by the waterside of rice fields, ditches and ponds, so as to catch all kinds of insects as a "special occupation".
Why can frogs catch so many pests? This aroused my interest. I caught a big frog and observed it carefully. Finally discovered its secret:
First, the frog has a "bug catcher", that is, it has a long, wide tongue as strong as "ya", and there is a lot of mucus on the tongue. When that frog found the bug, its tongue quickly tur out of its mouth and stuck the insect in its mouth.
Second, the frog's eyes are a pair of sensitive and abnormal "patrol devices". When a frog squats in the grass, as long as a bug flies in front of it, it can immediately find out and catch the bug quickly with a "bug catcher".
Third, frogs have many tiny teeth above their mouths. These teeth are not used for chewing food, but "insect-closing devices". Without these "insect-closing devices" in the frog's mouth, the subsidized insects will probably escape from its mouth.
Fourthly, in order not to be attacked by natural enemies, it is found that frogs have a suit of "protective clothing" adapted to the surrounding environment. Some frogs are yellow-green, because they live on wet rivers and green grass. While some brown frogs live in beaches and burrows, which greatly improves the efficiency of supplementing insects.
Frogs have so many magic weapons, no wonder they can catch so many insects. But a new question came to my mind again: Can frogs catch so many insects? Is it related to frog's "tactics"?
To prove my idea, I took a big frog to do an experiment, and found the frog's "tactics"-"braking with static pressure". I put the frog in the grass, and it just jumped a few times and squatted there motionless. I saw it holding its head high, bulging its big round eyes, as if staring at one place with rapt attention. What is it doing? Oh, it turned out to be quietly waiting for its food.
The frog's main "tactic" is to "suddenly attack and catch him unprepared". When a small flying insect sang a humming song triumphantly in the grass, the frog wearing "protective clothing", "insect trap" and "insect trap" stared at it with big eyes. Suddenly, the frog jumped up and the little flying insects disappeared. I'm really surprised: ancient frog is so fast that I can't see it clearly.
The number of ancient frog is amazing. Every frog eats about 60 pests every day, and in the eight months from spring to autumn, one frog can kill more than 10,000 pests. It has made outstanding contributions to the vigorous growth of rice and the harvest of crops, which is really remarkable!
Frog really deserves to be the "guardian of paddy field".
