Known as the "gentleman", the Antarctic penguin left a deep impression on scientists with its unique foraging way. When they feed their toddlers, they always do it while running. Penguin's parents know that in the Antarctic continent where food is scarce, those weak and fast-running chicks can't get enough food at all and will starve to death sooner or later. So they chose the method of feeding while running to protect those fast-running and competitive chicks. The laws of nature show that only strong offspring have enough opportunities to get food independently.

Mother fox is more systematic in educating her children. In the first step, they put the bitten vole next to their young son and let them bite and fight separately. Then encourage children to compete for food with each other. The third step requires the children to fight with the injured vole. Finally, in actual combat, take them to the Woods and fields to catch voles. The mother fox has this patience and can do her best to educate the little fox to learn to get food independently because of her love for the little fox.

After catching the injured antelope or zebra, the cheetah living on the African prairie did not kill it immediately, but deliberately let it escape, and then urged the cheetah behind to catch the prey. If the cubs are negligent, the females will beat and drive them away mercilessly until they understand their mother's intentions. After the fierce lioness threw down the antelope and bit it, she immediately used her roar to encourage her cubs to bite, and demonstrated how to tear open the antelope's stomach and feed on its internal organs. There is a simple reason. If the cubs don't survive, they will lose their chance of survival forever.

I didn't stop until I was full of energy and tried to catch up with the injured prey.

That's enough. That's enough detail.

Kneel for a satisfactory answer.
