There is a fish in the north, its name is Kun, the size of the carp, a pot can not be stewed, but also to buy two barbecue grills. Hello everyone, I am the demon wind, today we are going to talk about the grievances of the two ocean beasts.
Bucky Beast (Whale)
< h1 class="pgc-h-arrow-right" > whale evolutionary history: how to become a high-quality mammal? </h1>
It is said that 50 million years ago, a prehistoric animal that looked like a little husband and was as thin as a stray dog made a major decision that would affect future generations.
The little husband in Doraemon's dream is a bit god-like
It was too hard to carry bricks on land, and it aspired to become a high-quality mammal, and then plunged into the vast sea. Of course, this leap is not to kill itself, but to gamble on a bright future for future generations.
This prehistoric animal is the ancestor of cetaceans, Bucky, after plunging into the sea, it worked hard and constantly cultivated, successively experiencing amphibious chocobo whales, basically aquatic but also small short-legged Rhodes whales, to completely aquatic spear-toothed whales and ancient lizard whales, and finally spear-toothed whales due to different beliefs, parting ways and evolving into modern toothed whales and baleen whales.

Looking at the descendants of the whales who are now swimming in the world's oceans and at the top of the food chain, it is obvious that the Bucky Beast's stud winning is a mess, but it also lays the groundwork for the struggle between good and evil among future generations.
<h1 class= "pgc-h-arrow-right" > humpback whale and killer whale feud</h1>
On a seemingly calm day, Robert of the Southwest Fisheries Science Center in California, USA. Pittman once again observed this unusual phenomenon, when a pack of bloodthirsty killer whales was chasing a pair of gray whale mothers and children, a humpback whale inexplicably appeared, interrupting the hunt, and between 1951 and 2012 there were as many as 115 records of such deceitful behavior in humpback whales worldwide.
Is this a distortion of whale nature, or a moral degeneration, and why do humpback whales repeatedly destroy the good deeds of killer whales? And how can a humpback whale with a mouth full of hair brush break the killer whale with a mouth full of sharp teeth, sure that it is not here to scrub the killer whale? To clarify these questions, let's take a look at both whale species.
<h1 class= "pgc-h-arrow-right" > killer whale, ruthless killer</h1>
Killer whales, the ruthless killers of the toothed whale small-ordered dolphin family, are 8 to 9 meters long, with a spindle-shaped body coated in cold black and ruthless white, and the dorsal fin is like a thumb that like a thumb that is thumbs up, as if to praise its position as the supremacy of the sea.
They are good at group combat, smart and brutal, and rely on the aura of the grandmother effect, and the team combat ability has been greatly enhanced. You may not know what such a powerful grandmother effect is?
This is a pervasive phenomenon in animals such as humans, killer whales, and elephants, and its essence can be summed up simply as your mother breaking your heart for you. The female killer whale lives an average of 90 years, and when she reaches the age of 40, she no longer has children, and she spends the rest of her time focusing on helping her children. Males, on the other hand, usually have a shorter lifespan, with an average lifespan of 29 years and a lifetime of reproductive ability.
Usually the head whale of the killer whale swarm is an older female whale, and the members of the whale group are mostly her children, and the female head whale will not only help take care of the next generation of young whales, but also teach her children many ancestral tricks.
For example, how to use the water to shoot down seals hiding on ice floes, such as how to take advantage of the weakness of the creatures that will force a standstill after the shark turns over, and take the life of the great white shark.
Under the tutelage of the grandmother whale, the children of the killer whale will not have the slightest timidity and weakness even in the face of the whale-like, largest opponent, they concentrate on attacking the weak parts of the blue whale's tongue, lips, fins and so on, even if they are as large as the blue whale, they are difficult to resist, and eventually they are surrounded and eaten, and these cruel killer whales especially love to eat the tongue of the blue whale.
<h1 class= "pgc-h-arrow-right" > humpback whale, a tame and powerful sea man</h1>
Humpback whales, on the other hand, look much more tame, they are about 13 meters long, weigh about 30 tons, rely on the mouth brush-like baleen to filter small fish and shrimp, swimming looks not hurried like a calm old man. But don't underestimate the power of humpback whales because of this, although they are not armed to the teeth, they are armed to the arm.
Humpback whales, also known as large-winged whales
Humpback whales, also known as large-winged whales, have a huge pectoral fin of about 5 meters long and weigh about 1 ton, and are flexible and easy to control, often attached to sharp barnacles, comparable to the eight chopping knives in Ip Man's hand, dancing up to three or five whales can not get close to the body, patting on the killer whale, even if the shoot does not die, it is inevitable that the skin will open the flesh.
With two knives in hand, I have it in the world. Even humpback whales without helpers have the confidence of "I want to fight ten" and often dare to provoke killer whale swarms. For example, the humpback whale that rescued the mother and child of the gray whale at the beginning, after photo comparison, scientists found that this humpback whale also saved a north sea lion from a group of killer whales in 1988, and in 2003, it participated in another tiger mouth grab operation to save another north sea lion.
What's even more surprising is that many humpback whales can even come from thousands of meters away to interrupt the killer whale hunt, whether the killer whales are preyed by gray whales, seals, sea lions, or sunfish.
<h1 class="pgc-h-arrow-right" >humple whales why should they save these unknown sea creatures? </h1>
Scientists are still inconclusive, but it seems that clues can be found in some cases of clashes between killer whales and humpback whales.
Although killer whales do not pose a threat to adult humpback whales, they often try to attack relatively weak humpback whale pups. These cases may shed light on why humpback whales form a bond with killer whales, perhaps to protect their young whales.
But there is also a question, how does humpback whale saving sea lion seals have to do with protecting juvenile whales? Pittman argues that while small groups of humpback whales tend to be loose and unstable, they have very stable breeding areas, and they intervene in killer whale predation only to eliminate potential risks.
Humpback whales don't care who is rescued, it is the humpback whale cubs who are the best, can't you also tell the killer whales this field I humpback whale cover, don't do things here! Killer whales can't eat well in the humpback whale field and will naturally stay away from the sea.
Of course, there are also scientists who think that there may be no reason for this, humpback whales are natural sea men, and in the eyes of them full of justice, there is nothing more refreshing than a fat killer whale and defending marine justice.
Just like Master Ye said, the whale of Xi Wu, when encountering injustice, must stand up, just like people with a sense of justice will be generously praised and forwarded after reading the article. I'm a demon, see you next time!
