Small grass snakes hunt small frogs. What happens when small grass snakes meet large frogs? They can often only see a small part of the frog and so mistake it for a small frog. Note the little frogs too. You can hardly see them in the aquatic plants.
The grass snakes often cannot see them either. This video is like a moral story. At first it tried to catch the big frog directly then it used its brain and tried to attack from under water but result was same. At 1:44 we could see the snake just leaving behind his task completely. The snake made a good decision, leave the frog before itself become prey, this taught us in reality, if cannot win a fight, run, for your life!
