Yesterday answered a question about "why sharks don't eat dolphins", in fact, this question is all bad, but most of the answerers' answers are the same, that is, copied from the Internet, such as what "dolphins will attack sharks with high-frequency sound waves", "dolphins have a high IQ and can play dead sharks", "dolphins fight in groups and kill sharks", "dolphins are faster than sharks", "dolphins are killer whales, sharks are afraid of retaliation" and other absurd remarks.
The so-called "sharks are afraid of dolphins" is an outright rumor! Or more like a paragraph, a small cute text or yy.
This rumor has probably been about ten years, but after the processing of various self-media in recent years, it has once again exploded on the Internet, making countless netizens believe it to be true. Although various creature lovers continue to debunk rumors, such as a certain god "a man wandering" has repeatedly refuted this rumor with reasonable grounds, but the results are very small, I searched, the headlines have not yet been debunked articles on this issue, so I dare to use the knowledge I know to restore the real relationship between sharks and dolphins from all aspects, if you think I am wrong, you can come up with accurate evidence to refute me. Let's get started.
<h1>The first is a real picture of sharks attacking dolphins</h1>
Sharks attack dolphins, and the shadows under the water surface are suspected of bull sharks.
Hammerhead sharks chase dolphins.
Sharks attack baby dolphins.
Sharks chase dolphins, the second is sharks, and the two sides are of equal size.
Sharks bite the carcasses of dolphins, and sharks look like juvenile great white sharks.
Dolphins attack nurse sharks, and nurse sharks "sharks as their name suggests".
It's just a part of it, and there are a lot of dolphin carcasses that have been bitten by sharks, so I won't let it go here. The rumor that "sharks don't eat dolphins" is also self-defeating, these pictures are all from the Internet, it is easy to search, but why are so few people to explore the truth? Because in their assumptions, sharks are weaker than dolphins, which is related to the size of both sides.
<h1>Comparison of the size of sharks and dolphins</h1>
The largest surviving fish, the mild whale shark
There are many species of sharks, with nearly 500 known and unnamed species, the largest being the whale shark, which is 12.65 meters long and weighs 21.5 tons. This is followed by basking sharks, which are 12.27 meters long and weigh 19 tons, but they are filter-feeding sharks with a gentle personality and no aggression. The smallest shark is only 18-30 cm long. 80% of sharks are less than 1.6 meters long, and there are only a few sharks that can exceed 4 meters in length, probably whale sharks, basking sharks, great white sharks, megaloman sharks, tiger sharks, gray mackerel sharks, Greenland sharks, Pacific sleeping sharks, gray sixgill sharks, grooveless hammerhead sharks and so on.
Great white sharks
Among them, whale shark basking shark giant mouth shark is non-aggressive, Greenland shark and Pacific sleeping shark swim slower, and gray sixgill shark activity area is deeper. The only large sharks that are more aggressive in the sea are great white sharks, tiger sharks, gray mackerel sharks, trenchless hammerhead sharks and a very small number, which are also the "main force" of attacking dolphins. The most famous great white shark can be more than 6 meters long and weigh 2.5-3 tons.
Let's look at the dolphins.
Member of the dolphin family
The dolphin family is the largest family under the suborder Cetaceans, with nearly 40 species, the largest dolphin is the famous killer whale, the largest body length is more than 9 meters, the weight is close to 10 tons, and the weight can be broken, and the pseudo-killer whale and the pilot whale can be broken. The smallest dwarf dolphins are also more than 1.4 meters long and weigh more than 50 kilograms. In addition to killer whales, the combat effectiveness of pseudo-killer whales cannot be underestimated.
Pseudo-killer whales with teeth like steel nails
It can be seen that whether it is the largest or smallest (excluding whale shark basking sharks), or on average, sharks are smaller than dolphins, that is, most sharks do not have the advantage of attacking dolphins. Moreover, the gregarious nature of dolphins increases the advantage over sharks, providing conditions for rumor-mongers to make up various stories.
Most dolphin attacks on sharks are the work of killer whales, which single-handedly increase the record of the entire dolphin family against sharks, but killer whales do not represent the entire dolphin family! In fact, there is a very cruel truth, that is, killer whales attack other dolphins far more than sharks!
Killer whales attack other dolphins
Even if the killer whale is close to other dolphins, it still feeds on dolphins, and the main prey of the killer whale is marine mammals, because marine mammals have more fat and more calories than fish, and the main food of killer whales is sea lions/fur seals, seals, dolphins and other cetaceans.
<h1>Properly understand the relationship between sharks, killer whales, and other dolphins</h1>
Sharks and dolphins hunt sardines together
Sharks and dolphins coexist peacefully in most cases, sharks rarely attack dolphins, dolphins other than killer whales rarely attack sharks, and the two sides even round up sardines together.
Large sharks can kill small and medium-sized dolphins, and swarms of dolphins can drive away small sharks (people who talk about confrontation regardless of size are hooligans).
And killer whales attack sharks and other dolphins are the norm, killer whales attack other dolphins for predation, and attack sharks are mostly for fun and eliminate competition, this is not hatred, there is no revenge, this is the natural law of the jungle.
Even the pseudo-killer whale can not escape the killer whale hunting, although the pseudo-killer whale is also very strong, but compared with the killer whale is still weaker, as for the confrontation between the killer whale and the great white shark, in fact, there are very few, not even clear videos and pictures, the recorded killer whale attack on the great white shark is only more than ten incidents, the killer whale's interest in the great white shark is far less than other dolphins.
<h1>About the various ways dolphins fight sharks</h1>
Let's take a look at the dolphins' methods of fighting sharks circulating online, and I will refute them based on what I know.
"Dolphins use high-frequency sound waves to deter sharks!" - The echo positioning of dolphins is used for fishing and communication, and it is not determined that they have the ability to attack.
"Dolphins have a high IQ and can play with dead sharks!" - This must be the size of the dolphin dominant, if the dolphin is much smaller than the shark IQ is useless!
Shark's shield scales under a microscope
"Dolphin swarms fight and kill sharks!" The shark's skin is not smooth, covered with rough shield scales, dolphins will scratch themselves when they hit the shark, and there is no record of dolphins hitting sharks.
"Dolphins are faster than sharks!" This statement is not entirely correct, dolphins usually have a speed of 55 km/h, longfin mackerel sharks can reach a speed of 60 km/h, and shortfin mackerel sharks can reach a speed of 70 km/h.
"Dolphin's big brother is a killer whale, and sharks are afraid of revenge!" - Pure yy, killer whales really like dolphins, because dolphins are fragrant!
<h1>The reason why such rumors are widely spread - like X and dislike X's network environment</h1>
In most people's minds, dolphins are cute, intelligent, kind, close to people and even save people falling into the water, sharks are ugly, ferocious, attacking villains!
In this environment, it is normal to belittle sharks and beautify dolphins, and even package dolphins as natural enemies of sharks (the term natural enemy cannot be used indiscriminately). And this rumor satisfies the fantasy of many people - such a cute dolphin, the shark can't beat it, it is safe.
The mud bombardment kills dolphins, far more ferocious than killer whales and sharks!
It's ridiculous! Mud bombardment kills so many whales and dolphins every year, why does no one come out and condemn two sentences? In fact, most lies take advantage of people's love and fear.
People are afraid of death, and some people have made up rumors that "lighthouse jellyfish will never die", which is actually just asexual reproduction.
People are afraid of aging and worship eagles, and some people make up "The Rebirth of the Eagle", which is nonsense throughout!
People talk about cancer discoloration, and some people make up the lie that "sharks must not be cancered", resulting in millions of sharks being killed every year.
<h1>epilogue</h1>
Nowadays, it is not unusual for Online rumors to blossom everywhere, but it is easy to know the truth, but many people prefer to listen to some rumors, because rumors are much better than the truth! For the sake of this nothingness, he does not hesitate to distort the facts, deny the laws of nature, ignore the laws of survival, and impose subjective assumptions on animals.
Just how beautiful the so-called lies are, how cruel the reality is! There are no fairy tales in nature, only the weak eat the strong, and the same is true of human society.
