Hello everyone, it's time for "Tao Brother to Live Blindly", today I will give you a nagging natural enemy in the ocean.
Before opening a nagging, I said a cold knowledge, which is also the last article to write amazon someone private message to me.
Oops, Amazon Forest Fire? Brazilian farmers cut down crops indiscriminately? If the Amazon rainforest disappears or desertifies, will we Chinese lack oxygen? After all, the lungs of the earth are screaming
How scientists analyze Tao Ge does not know, but judging by my shallow knowledge, it should not be.
Because of the earth's oxygen supply, forests account for less than one-fifth of it, and the Amazon rainforest only occupies one-fifth of the surface forest, so even if the Amazon rainforest is gone, the oxygen concentration will drop by less than 4%. In the past 50 years, oxygen concentrations have decreased by more than 10% due to human activities, and areas have abounded.
Therefore, the Brazilian government allowed their farmers to cut wood, or acquiesced to the fires engulfing the rainforest, which had little impact on the people of the world, and they themselves were quite hurtful.
Why should we bother with this broken thing? Let's get to the point.
One-fifth of the oxygen comes from the forest, so who is providing the rest of the oxygen?
Algae in the ocean.
Big fish eat small fish, and small fish eat shrimp rice. What do you eat with dried shrimp?
Eat seaweed.
In fact, seaweed, as the bottom of the food chain in the ocean, is not only the problem of shrimp eating? Almost all small sea creatures are "natural enemies" of seaweed.
Take the sea urchin, for example.
We all know how to eat sea urchins, pry open the shell, eat it directly raw, and it is incomparably sweet.
But do you know how sea urchins eat? The sea urchin's mouth is at the bottom and looks quite ferocious:
Zoom in a bit:
Don't underestimate these 5 teeth, they are one of the most special structures in the animal world, evolved for more than 200 million years, as sharp as a blade, and can even chisel through stones, and even human excavation tools borrow the structure of sea urchin teeth.
So sea urchin eats seaweed, is there any big problem?
Sea urchins are full of thorns, and generally creatures are not good at mouthing, so we can often see the news of sea urchin flooding. But when one thing drops one thing, when encountering natural enemies, there is no reason to talk about it.
For example, pufferfish (stingray).
This product is no stranger to everyone, it is poisonous. But few people know that its power is not limited to the neurotoxin that can make the natural poison TOP5, but also the teeth of a cow X.
Then you ask me, very few people know, why do you know Tao Brother?
Because when I was fishing in the sea, I saw someone get bitten by a stingray. Take a look at the image below:
One bite is like this
It was lucky, because I did another experiment later, and Red Bull cans know, right? It's not aluminum, it's iron!
So the sea urchins, like melon seeds, are gone.
The puffer fish (stingray) will bulge into a ball to protect itself when it encounters danger, but this move is not good in front of the fierce Pippi shrimp, because the two small fists of the Pippi shrimp are really not convinced.
Pippi shrimp tried to drag the stingray into the hole, but the ball was too big to get stuck
As long as you aim at the belly, you will immediately vent your anger, and in front of the "fist of emptiness" of the Phi Phi shrimp, the stinging puffer is really too fragile.
It was dragged back into the hole
Let me put it this way, pippi shrimp this pair of fists, more technically called jaw foot, once activated, can make the speed reach a staggering 104 km / h in 3 milliseconds. Why is it called the "Fist of Cavitation", because this level of speed is enough to trigger the "cavitation phenomenon" underwater - in layman's terms, it is to form a "void space" in the water, imagine what it is like to shoot underwater at once?
3 milliseconds can accelerate to 100 miles, if you can make the Phi Phi shrimp continue to accelerate for 1 second, theoretically can fly out of the earth, the first cosmic speed is just that.
So Phi Phi shrimp rely on the "fist of cavitation", the fish blocks the fish, the crab blocks the crab, no matter who you are, go up and do it.
One punch directly broke the crab leg
One punch to crush shellfish
But Phi Phi shrimp also has weaknesses, that is, the body is too small, the longest is less than 20 centimeters, nature in most of the time to follow the "who is big who cattle X" principle, Phi Phi shrimp is fierce, in the end is still a shrimp, encounter a slightly larger carnivorous fish no tricks.
For example, moray eels.
Moray eels prey on Pippi shrimp
Moray eels are long snake-like fish, with a wide variety of species, in a sense, similar to Wang Ba- as long as they bite, they will never let go!
The most tyrannical of the eels is the wolf eel, which is not a fuel-efficient eel by name:
This cargo looks very unfriendly
The most powerful thing about the wolf eel is that it is too capable of biting, the following wolf eel has hung up, there is only one head left, but it can still bite a bit of what is sent to the mouth:
The key is that there is a thick layer of pads on the jaw, so that they can not be injured when they bite some "abnormal food", and it feels like it was specially evolved to eat armor-like creatures.
One bite at a time, crunchy
But wolf eels also have times when they roll over, although they are not "natural enemies", but the existence of octopuses can indeed be described as an outlier in the ocean.
In the impression of many people, octopus ≈ small balls, as if it is born as an ingredient, whether in front of the food stall or in the vast ocean, but in fact, this is not the case, this cargo is fierce, quite fierce.
Octopuses prey on moray eels
Although this eel is not a wolf eel, the process is relatively common. The moray eel felt that the octopus was soft and sticky Q bomb, chased, forced the octopus into the hole and still did not spare, the octopus thought that it was intolerable, so the Jedi counterattacked, and dragged the moray eel into the hole with only one tentacle.
The octopus's "multi-tentacle + high IQ + salivary toxin" traits allow it to face prey of its own size without any fear. For example, the following fish died under the octopus suction cup + saliva toxin:
Passing by a fish, Caught
Struggling is useless, and being entangled in an octopus is basically seen in the next life
But it is still this sentence, who is bigger and who cow X, octopus is smarter, in the face of larger fish, there is only a share of being crushed.
Many large fish have octopus in their recipes, such as giant groupers.
Speaking of this cargo, I have also fished in the United States, a 300 pounds, so hanging did not exhaust me.
Legal policy protection, not allowed to pull on the boat, can only jump into the water for group photos
The strength of the giant spot is all written in the name, the giant, nothing else, is the world is very big, you bear with it.
When it opens its mouth, all the bells and whistles are invalid, don't care whether the octopus or the squid, come in
This terrible sense of oppression
Where the mouth of the giant mouth passes, there is no grass
Even small sharks, when they see giant groupers, can only turn their heads and slip away:
Otherwise, the end can only be:
The baby shark was swallowed by the grouper
The largest of the groupers is the giant grouper, but the sharks also have large heads, the most famous of which is the great white shark. Grouper bullying and bullying small sharks is just that, really meet the great white shark, or that sentence: see you in the next life.
A great white shark that swallows a grouper in one bite
Speaking of great white sharks, it is indeed a hegemon of the ocean, a mouthful of fangs to catch who bites whom, the water needless to say:
Eat seals
Even the heavens do not spare:
Great white sharks eat seabirds
The key is to get hungry and I eat myself!
Great white sharks eat small white sharks
So no one can cure this thing?
How can it be? Killer whales can.
Great white sharks have an average body length of 3 meters and an average weight of 2 tons.
Killer whales have an average body length of 5 meters and an average weight of 5 tons.
The visual visual gap between the two is roughly as follows:
It feels like if the Great White Shark goes out to fight, it's not completely out of chance, right?
There's really no chance of winning.
The great white shark didn't even have the guts to go out and fight. This is not what I said blindly, but the conclusion of an American study called Jorgensen - as long as there are killer whales in the place, the great white shark simply chooses to slip away, and within a few months, it will not come back.
Jorgensen's paper
This brother is a senior researcher of an aquarium, by chance, he found that the great white shark will hide from the killer whale, looking back at him and the research team to think, can not ah, is this great white shark particularly instigated ah? So he went to the Faralon Marine Reserve to mark 17 sharks and tracked the location through a tracker, the forefoot great white shark is still eating small seals very happily, and a group of killer whales on the back foot come to the same water.
So at about the same moment, the shark quickly left the water and did not dare to swim back for half a year. Jorgensen did not die, and in 7 years he successively marked 165 great white sharks, and found that all great white sharks would choose to flee after encountering killer whales.
This is very interesting, animal instinct does not deceive people, great white shark genes think that they can not do killer whales.
The reasons are not complicated, mainly 4 points:
First, the difference in body shape, this point has been mentioned above, and will not be repeated, anyway, it is a primary school student's military body punch, and it is impossible to beat a college student with normal development and no disability. One meaning, just understand it.
Second, the great white shark is a solitary animal, living its own life. Killer whales, on the other hand, are social animals, coming and going. One who hit 10 is Ip Man in the movie, definitely not a great white shark.
Third, the great white shark brain is not as good as the killer whale, the great white shark is a fish after all, and the killer whale is a mammal, and the intelligence has the absolute upper hand. In fact, the main means for killer whales to deal with great white sharks is to bite the fins and turn the face of the great white shark, due to the restriction of "forced hard straight", as long as the shark's stomach is facing the sky, it is basically a state of "allowing the whale to be slaughtered".
Fourth, killer whales have a super high population intelligence inheritance and social communication, they not only hunt together, but also raise offspring together, passing on the experience from generation to generation. This is very interesting, because this means that each killer whale group has its own cultural characteristics, some killer whale groups are more peaceful, they specialize in picking small fish and shrimp to eat, some killer whale groups are more tyrannical, filling the stomach is a physiological need, and the spiritual need is to find a dry fight with great white sharks. Encounter this, you say if you are a great white shark, why not?
Do killer whales have predators?
Sorry, but not really.
Oh, yes, we humans. No matter how domineering you are in the sea, you should be allowed to perform the show, and you have to perform:
Well, I am Tao Brother, can fish and talk, if you also like fishing, like food, like the customs and customs of all corners of the world, be sure to pay attention to me! I'll tell you in my article – the world is really big.
