On the earth, no matter what the environment, in fact, is full of creatures of the fittest, life evolution always appeals to a lot of magic and weirdness, individuals in the world have their own unique lifestyle, but also have amazing life-saving skills.
According to Darwin's "The Origin of Species", in this natural hunting ground full of hunting, creatures that can survive to the present day are not only supernatural talents, but also have perseverance, and evolution is the only law for creatures to improve their survival rate, and it is also the most convenient way.
But there are also different forks in the path of evolution, and some animals choose to improve their defense skills, cooperate with nature, and take the route of camouflage and stealth, such as the Malay leatherback tree frog, the bamboo bug and the flounder.
Some animals choose to evolve their own attacks, using their teeth and claws to symbolize power, such as jackals, tigers and leopards, wild boars, rhinoceros, and so on.
The above are evolutionarily successful species, but evolution does not represent 100% success, some species because of excessive force in the process of evolution, the final result is not completely pessimistic, but failed evolution, to their own survival has brought a lot of trouble, even fatal blows.
The first to shine is the praying mantis
I remember watching "Black Cat Sheriff" when I was a child, and the active dedication clip of the male mantis "life is precious, love is more expensive" still fresh in my memory, but this kind of love is higher than life, and the behavior of male animals voluntarily sacrificing themselves to supplement nutrition for female animals does not actually exist in the real world.
As the saying goes, tiger poison does not eat seeds, but in nature, male animals are eaten by female animals after mating, which is equivalent to "murdering their husbands", which is actually not uncommon in insects and arachnids, and this special phenomenon has a professional term in the biological world, called sexual eating.
In order to avoid being eaten in one bite after mating, many insects have also evolved unique life-saving skills, such as the male spider in Longxi feminine spider, which has evolved a unique hydraulic elastic joint in the body, and once the mating is completed, it will eject at a speed of 88.2cm/s and flee the scene.
The strange park spider will send rich food to the mother spider before mating, and complete the mating process while the mother spider is immersed in enjoying the food.
However, the male praying mantis is not so lucky.
Whenever the male mantis and the female mantis do "indescribable" things, the female mantis will use the "big knife" in her hand to hook the male mantis's head and bite it off when the two sides are most affectionate, and then chew into the abdomen, and the male mantis who has lost its head will still hold the female mantis tightly, looking like death, which is really incredible.
However, the instinct of animals is to survive and reproduce, and nothing is more important than these two, female praying mantis needs food in order to survive, and in order to reproduce, more sources of nutrition are needed, male praying mantis is undoubtedly the most convenient and nutritious preferred food source.
Although this evolved sexual eating behavior is full of cruel cannibalistic nature, it at least allows the male praying mantis to enjoy a pleasure of "dying under peony flowers, ghosts are also merry" before death, which is also worth it.
The deer dolphin is known as the "Tihua Show"
Deer porpoises are a group of wild boar-like creatures that live mainly on Indonesian islands, and apart from the abrupt teeth of the mouth, there is not much difference from pigs in other respects.
This is an omnivore, both vegetarian and occasionally meat-eating, the favorite food is native to the Indonesian island of Malaya Gale, a poisonous plant full of hydrocyanic acid, which can also allow this group of deer and dolphins to swallow the fruit and fully absorb and digest.
The peculiarity of the deer dolphin is that it has two pairs of fangs, one pair protruding from the lower jaw, while the other pair is just the opposite, protruding from the upper jaw of the deer dolphin.
But these fangs have one thing in common, that is, they are invariably curved backwards and are very fragile, making what could have been used as a defensive and offensive weapon by deer and dolphins appear useless.
On the contrary, these abrupt things that do not match the "painting style" of the deer and dolphin body block the eyes of the deer and dolphin, greatly affecting their vision, fortunately, they mainly feed on nuts and plants, if they are carnivores, they will inevitably occupy the upper hand during the hunting process and cannot be hungry.
And some deer and dolphins that are too well developed, the evolved fangs will stretch back wildly, and even pierce the deer and dolphin's own brain, completing a self-killing act for no reason.
According to locals, the fangs of the deer dolphin and the hammock hook serve the same purpose, and in the fierce and cunning and hunted primeval forest, the deer dolphin will hang itself on the branches with its fangs when napping in search of absolute security, which explains why the fangs of the deer dolphin appear curved.
Can kill their own goats
Where there is a sleeping dragon, there must be a phoenix chick. The fate of the pan sheep seems to have a lot in common with the deer and dolphins.
Pan sheep are actually very common in our lives, mainly distributed in the highland desert areas of Central Asia, of course, on the top of some snowy mountains can also see their sturdy figures, and deer dolphin fangs are slightly different, the most prominent part of the pan sheep is their horns, and the same thing is that they are curved.
The curved horns of an adult male coiled sheep are larger than their entire head, and the curved horns of the male coiled sheep grow slightly laterally from the top of the head, and then make a 180-degree turn, winding downwards, showing a clear spiral angle.
Many scientists have not understood what the huge and thick horn bases of the sheep do, as if they can no longer see what magic they have except to help them in the process of fighting mates.
On the contrary, the horns of the pan sheep seem to grow endlessly, even in the twilight years, although the growth rate of the sheep's horns will slow down, but will not stop, then the problem arises, these in the prime of the pan sheep has been close to its jaw horn tips, in its older, there will be a certain chance to pierce their head, thus dying.
This is also a failed evolution.
Bull shark who survived
Sharks we are all familiar with, a very combative sea creature, and the bull shark we want to talk about, but can break through the limitations of the ocean, enter the freshwater river, and become a real "battle shark" in the shark world.
Bull sharks are extremely combative, on the one hand, because they are not small and have erect sharp serrations, on the other hand, they have a "knife and gun", like a black hole stomach, these sharks like to inhabit the coast, estuaries or shallow bays, usually feed on fish, sometimes also eat smaller than their own kind.
In addition to the fact that these marine animals can be regarded as a delicacy in the belly by the bull shark, the bull shark also often devours fallen humans, cats and dogs, seabirds and even garbage, etc., the stomach of the bull shark seems to have a quality that can never be filled, supporting them to either eat or on the way to feed all day round.
The exterior of such a scenery also has an indescribable interior.
For a powerful population, it is not the external forces that can disintegrate them first, but themselves. With its own stomach, the bull shark almost tasted everything in the water that could be swallowed by itself, and the human garbage that could not be digested and accumulated in the belly of the bull shark for many years became the last straw that crushed the bull shark.
The bull real shark can't imagine that he has such a strong appearance, and he was actually played bad by himself, it is worthy of being a bull is really "stupid", what is it like to hold up to death? The bull shark said that he knew it well.
Coupled with the fact that they often live in coastal areas where humans are active, water pollution and waste pollution caused by human industrialization have accelerated the demise of bull sharks.
brief summary
Biological evolution in nature is actually a process of trade-off, the prominence of one aspect is bound to lead to the weakening or even death of another aspect, only wisdom is the real law of species reproduction.
Evolution does not mean success, but failed evolution, as mentioned at the beginning of the article, even if the surviving animals do not appear extinction, but also add a lot of trouble to their own lives, at least, there are corresponding troubles.
