Stone flowers live in desert areas in southern Africa. Its color and shape are lifelike with pebbles. Its leaves are thick and juicy, covered with pebbles and can store water. The original stone flowers are golden yellow and very beautiful. Moreover, a plant only blooms one flower, and it will wither after only one day. Of course, this is how raw stone flowers deceive animals and avoid being eaten. Raw stone flowers like to be accompanied by gravel and rocks, and it is difficult to survive without this environment.
3 camel's perseverance and a long way to go.
A special kind of dandelion grows in the desert on the east coast of the Mediterranean. It won't prolong life as usual. If there is no rain, it will not germinate and bloom all its life. But as long as there is light rain, no matter when it rains, they will seize this rare opportunity to sprout and blossom quickly, and seize the time to finish the fruit and spreading before the rain evaporates. Residents in the Middle East often give it as a gift to relatives and friends, because if you bury it in a flowerpot, it will take root, sprout and blossom as long as you don't forget to water it. Israelis mainly give it to those who are smart and poor. They believe that in this world, the opportunities for ordinary people to develop themselves and improve themselves are as poor as dandelions in the desert when it rains, but as long as they have the same qualities as dandelions in the desert, once the opportunity comes, they will resolutely seize it and boldly practice it, and they will also become rich and great people.
It turns out that dandelion plants in the desert are planted in flowerpots to remind people from time to time: don't be pessimistic and disappointed when encountering difficulties, don't complain, just wait patiently for opportunities; And once the opportunity comes, we must pounce decisively and seize it.
The sparrow's spirit of "give me liberty or give me death".
There is also a bird called Scissors Gull. Its beak is short in the upper part and long in the lower part, like a pair of scissors. When fishing, it flies close to the water surface and puts its lower beak into the water. If you meet or see a fish, it will quickly close the upper part of its beak. But this is usually very dangerous. If you hit a reef or other hard objects hidden underwater, it will break a section of its beak because it is too late to take it back. However, the seagull family did not give up their hunting methods because of this. Maybe they understand that life is doomed to pay a price or make sacrifices, and no one can go through life without paying. The law of life is always: if you want it, you have to pay it first.
Sea otter: Race against time In the waters near the Aleutian Islands, there is a very clever marine mammal-sea otter. In front of whales and seals, it can only be considered a small man, with a body length of only 1.5 meters and a weight of only about 40 kilograms. However, from the perspective of predation, it is still better. For example, in order to enjoy the delicious sea urchin meat, the sea otter will first try to pick up a stone from the bottom of the water, lie flat on the water, then put the stone on its stomach, then hold the sea urchin tightly with its two front paws and hit it hard until its hard shell breaks. Sea otters can not only skillfully use stones as chopping boards, but also accurately grasp the predation time. Every time you dive, the sea otter can only last for 4 minutes. If you hunt in the sea below 50 meters for more than 4 minutes, you will drown. The sea otter, which lives in the sea for such a short hunting time, can't relax at all once it dives into the water, let alone delay 1 second at will, but aims to find its prey accurately.
Black heron: Black heron is a kind of bird living in Africa. It lives by a strange way of predation. Standing in the water, it first spreads its wings into the shape of an "umbrella", then curls its head in the "umbrella" and waits for its prey to appear with its pointed beak. It's those small fish and shrimps who like to find shallow and cool places. So the shadows of trees or tall aquatic plants are their best choices. The black heron waited quietly, a small fish got into the "shade" it created, and then a small shrimp came ... Of course, the only thing waiting for them was a dead end.
In this way, the black heron can wait for the prey to be delivered to the door naturally, which skillfully uses the living habits of fish and shrimp.
