The great white shark is one of the most dangerous animals in the ocean, and its sheer size and terrifying teeth make it look chilling. But in fact, the great white shark has fewer injury incidents, and more is to carry the pot for another shark, this fierce shark is - bull real shark.
Because the great white shark is more profound in everyone's impression, so people will see their own sharks that look like great white sharks as great white sharks, and all sharks that look like sharks are great white sharks, so there are more cases of great white sharks hurting people in the world! Just kidding, but the great white shark really carried a lot of hurtful cases for the bull shark.
There are three types of sharks in the world, namely the ferret shark, the man-eating shark (great white shark) and the bull shark. Although in terms of body size, the man-eating shark is the first, the ferret shark is the second, the bull shark is the third, and the bull shark is the smallest of the three, but the bull shark is the most dangerous of the three. As for why it is the most dangerous, listen to me.
Bull sharks are small, and females will be larger than males, about 1.8-2.3 meters, the longest can reach 3.24 meters, and the weight can reach 220 kg. Bull sharks have a special ability that no other shark has, and can switch between salt water and fresh water at will. Don't underestimate this ability, which allows the bull shark to prey more and survive better.
Sharks survive in brackish water because they contain trimethylamine and urea, and seawater is needed to regulate the balance. When the bull shark enters the fresh water from the ocean, its special kidney plays a role, which can quickly deal with the fresh water that is toxic to the bull shark, and exclude it with a 15 times the urination rate, so that the bull shark can live in freshwater waters and prey.
Bull sharks can swim fast at a speed of 15 km/h in fresh water, but in turbid fresh water, they rely more on their ability to smell than the sight bull shark. The front end of the bull shark's mouth is covered with many gelatinous electric receptors, and the front end of the bull shark's mouth has a special receptor called "Laurel's pot belly", which can detect the weak electric field emitted by nearby organisms, which is more powerful than the sense of smell, and can also make the creatures in muddy water invisible.
It is with this ability that the large food around it also wants to taste, it is like eating leopard bile, unscrupulous attack, but in the animal kingdom, weight, body shape is the representative of strength, bull sharks are more killed, become a delicacy sent to the mouth.
The bite force of the bull shark is also the largest among sharks, the bite force of the great white shark is 450kg, while the bite force of the bull shark is 590kg, although it is small, but the bite force is amazing. Combined with the serrated fangs on the edge of the bull shark, it can easily penetrate the prey, and the jagged teeth between the teeth can easily shred the meat of the prey like cutting vegetables.
Bull sharks are dangerous, and you can meet such dangerous guys in freshwater rivers.
Bull sharks have many names, such as bull sharks, bull white-eyed mackerel, bull sharks, white sharks, etc., and have different titles in different river basins, in India, bull sharks are called Sundelbans sharks or Ganges sharks, while in Africa bull sharks are called Zambezi sharks, in different places it has different names.
It's like some places are called sweet potatoes, some places are called sweet potatoes, some places are called sweet potatoes, red amaranth, sweet potatoes, etc., in fact, they are all the same thing!
The reason why it is called a bull shark is because this shark is more robust, and it is a spindle-type body in the shark family, but this guy is a spindle plus body, in fact, I think it should be called a pig shark more appropriately. The bull shark is short-tempered, wide-feeding, bold, almost live around the fish are a dish on its menu, sharks, crocodiles, hippos and other animals that are much larger than it dare to attack. Even small people of its kind do not refuse, humans are also a delicacy of its kind, it will even use its strong body to knock over the boats on the river, crash and sink.
The stomach of the bull shark is like a refrigerator, which can preserve food, but it can only be stored for about ten days, so that it can provide energy for the body when the bull shark has no food, but the bull shark will generally hunt once in 2 to 3 days, and it is extremely greedy and gluttonous like a gluttony. Someone once found a stranded bull shark, a closer look at the original death, in its stomach found many animal body fragments, and some garbage, it is estimated that the bull shark as a delicacy to enjoy.
The bull shark's eyes are very unique, in the aquarium we see the great white shark eyeball is completely black, and the bull shark's eyes have a focus, you can see where it is looking. I won't tell you that this was said by a man who survived being attacked by a bull shark.
