Can a sandfish beat a blue whale? Why can t sharks beat killer whales?

Shafish can't beat blue whales.

The blue whale (scientific name: balaenoptera musculus) is a marine mammal belonging to the suborder Baleen Whales. There are four subspecies.

The blue whale is believed to be the largest animal known to have ever survived on Earth, reaching up to 33 meters long and weighing up to 181 tons. The blue whale has a slender body and a blue-gray back, although it can sometimes be lighter in the water.

Like other baleen whales, blue whales feed mainly on small crustaceans (such as krill) and small fish, sometimes including squid. Blue whales usually feed at depths of more than 100 meters during the day and come to the surface at night. Blue whales begin mating in late autumn and continue until late winter, with females usually giving birth every 2-3 years and calves at the beginning of winter after a gestation period of 10-12 months.

It is distributed in all four oceans.

The confluence of warm water and icy sea water is an excellent habitat for blue whales, the cold water is usually rich in plankton and krill, blue whales usually feed on these two creatures, blue whales are distributed worldwide, with the largest number in Antarctic seas, mainly temperate and cold cold waters with water temperature of 5-20, and a few whales have come to swim in the Yellow Sea and Taiwan waters.

Adult blue whales have no natural predators, thirty killer whales can't take an adult male blue whale, and it's not difficult for thirty killer whales to kill hundreds of great white sharks. At a speed of fifty kilometers for a blue whale, a great white shark can be smashed into the shark's mouth with its body, and the killer whale has to kneel with a tail sweep.

Obviously, it can't be beaten, because the big white shark is a fierce, cruel and bloody animal, but the great white shark is a notoriously solitary creature.

The smallest member of the cetaceans has been practicing the great white shark alone, and a group of dolphins can dare to walk the great white shark. So not to mention the huge blue whales. When an adult blue whale is an adult, there is nothing it can do about it, even a group of killer whales, which are the dominant killer whales of the sea!!

So the great white shark can't beat the blue whale. The whale shark, the largest member of the shark family, is toothless like the blue whale and has the same gentle temperament as the blue whale. Naturally, he can't win against the blue whale that is as gentle as himself, but much larger than him in size and tonnage.

So the sharks can't beat the blue whales. Juvenile blue whales are also protected by female whales, so they don't need to be afraid of sharks.

Generally, whales can't be beaten, and the size of the whale is much larger, and they are in different locations, so there is no chance.

Sharks are aggressive, and blue whales can't compare to sharks if they eat plankton, so they can beat them.

Why are sharks, as the overlords of the sea, afraid of killer whales?

Sharks are known as the kings of the sea, but sharks also have natural predators, they are afraid of killer whales, why is that? First of all, let's introduce sharks and killer whales.

There are many species of sharks in the world, more than 80% of sharks are less than meters long, and the largest shark in the shark is called the whale shark, which can reach 20 meters in length. Great white shark is one of the most ** sharks, widely distributed in the coastal waters of all oceans, great white sharks are a large predator, they are active during the day, they prey on a variety of fish and sharks, in our records there are records of great white sharks attacking humans and fishing boats, great white sharks are considered to be one of the three most dangerous sharks to humans.

Killer whales belong to the dolphin family, the genus Killer Whales. Cunning, greedy, brutal everyone's understanding of killer whales, killer whales can be seen in all seas of the world, and it has an extremely wide distribution. Killer whales live in groups and like to live in groups, they have one or two living together, and there are forty or fifty living together, in group life, killer whales take care of each other and support each other, and the older killer whales will teach the younger killer whales the skills of hunting and raising their offspring.

If a member of the group is injured, the other killer whales will come to his aid. Perhaps no other animal in the ocean would dare to provoke killer whales in this kind of group life.

So much has been introduced, now let's explain to you why sharks are afraid of killer whales? First of all, the first reason is that big sharks are generally solitary animals, they often appear alone, and killer whales are different, just introduced that killer whales are social animals, once the shark meets the killer whale, naturally the more numerous side wins, so the shark can't beat the killer whale. All sharks have a fatal physiological weakness, scientists call it tonic stationary When the shark's body is turned over, the shark will enter a tonic stationary state, in this state, the shark will lose all defense, then the shark will have no way to take the killer whale, therefore, the shark can't beat the killer whale.

Megalodons can't beat blue whales.

The megalodon has a body length of 13 to 18 meters and weighs 30 to 50 tons. Blue whales can reach a length of up to 30 meters and weigh up to 200 tons. One is that the size gap is too large, and the other is that the megalodon does not swim as fast as the blue whale.

While megalodons have the ability to hunt large baleen whales, there is also an upper limit. The large baleen whale of the same period as the megalodon was 17 22 meters long and weighed 60 85 tons. In this range, the Megalodon is predatory.

Whales are not inanimate animals and will resist when they are in danger. Instead of being bitten motionless. Predators can still be dangerous when hunting, especially if they hunt prey that is larger than themselves.

Megalodons mostly prey on smaller whales and hunt large baleen whales much less often.

So, when the whale is comparable in size to the megalodon, the megalodon has the ability to prey on them. After all, the megalodon has a bite force of 18 tons and is huge. And for the larger baleen whales, the megalodon will not be rash.

Because, the hunter will keep himself as uninjured as possible, so that it can be hunted later.

Extinction theory

It has been theorized that since the megalodon mainly feeds on cetaceans, the water at the poles is too cold for megalodon to survive, so the whales can escape the predation of megalodon, causing the megalodon to become extinct due to lack of food.

Other explanations suggest that any impact on the food chain (about 1.5 million years ago, the Earth's water cycle changed, upwelling decreased, large numbers of cetaceans died due to lack of food, and there were fewer diverse whale species) would be eliminated by predators with huge metabolic demands. However, a few scientists have pointed out that the megalodon is still extinct and is still alive today.

There have been many reports of the sightings of megalodons, and after testing, they have mistaken large sharks such as basking sharks and whale sharks for megalodons. The reason for its extinction is speculated to be due to the fact that about 1.5 million years ago, the Earth's water cycle changed, the upwelling decreased, a large number of whales died due to lack of food, the diversity of whale species decreased, and the megalodon could not find enough food and gradually became extinct.

Sharks generally can't beat whales.

While some large, ferocious sharks can beat smaller and gentle whales than Wu Lusui, they can't beat ferocious whales and particularly large whales. For example, killer whales are a fierce type of whale, they are the natural predators of sharks, and sharks can't beat them. Blue whales are the largest whales, and sharks can't beat them.

And those sharks that are smaller in size are generally less able to beat whales.

Sharks and whales are both animals that live in the ocean, and they are relatively high in the food chain, and there are many animals that can be preyed. There are many species of whales, and whether sharks are afraid of whales needs to be discussed on a case-by-case basis. Although whales are relatively large, many whale species are relatively mild, so sharks are not afraid of these whales.

Reasons to take blue whales as prey:

At present, scientists have observed only 4 to 5 cases of killer whales killing blue whales, and these ** blue whales are all sub-adult individuals. In the two examples we gave above, the first ** killed the blue whale with a body length of 15 meters, and the second with a body length of 18 meters. The blue whales that killer whales choose to kill are all sub-adult blue whales, which are inexperienced and much smaller than adults.

The reason why killer whales have a higher ecological niche than great white sharks is that in addition to their large size, they are also very socially related. Killer whales are highly social in groups, ranging from a few dozen to hundreds of individuals per population. It's like a bunch of tigers coming together on land, and in the ocean it's definitely something that most creatures are afraid of.

Sharks don't dare to bite the whale, and the sheer size and strength of the whale are enough to deter sharks.

Whales have toothed whales and baleen whales, baleen whales do not have biting teeth, and toothed whales have sharp teeth. Baleen whales eat small shrimp and small fish, and toothed whales eat big fish and meat. Sharks also have docile ones, such as whale sharks, and different sharks will have different effects when they meet different whales.

1. Generally, shark hunting whales is done in group cooperation.

When baleen whales encounter sharks, they are usually attacked by sharks, especially blue whales, which are used as food by many species of sharks.

However, blue whales have thick skin and thick subcutaneous fat, which is not easy to be bitten to the fatal point, and they will die if they are directly hit by the tail of the blue whale in the process of hunting it.

2. If you encounter killer whales and sperm whales, which are quite aggressive toothed whales, sharks dare not go wild with their tails between them.

3. If the toothed whale encounters a shark one-on-one, and assuming they want to fight, the shark's doom will come.

And, in general, toothed whales include baleen whales in their diets.
