Xiang Yang watched a video about great white sharks on the Internet.
In the video, a great white shark and a marine fish were swimming towards each other. The great white shark clearly did not bite the marine fish, but the marine fish's skin was instantly torn apart. The reason for this was caused by the terrible barbs on the great white shark's body.
At this point, Xiang Yang suddenly shook his head. "No matter what the attitude of great white sharks is towards humans, their numbers are decreasing. If we don't protect them, I'm afraid our descendants will never see them again."
"Protect? Protect such a dangerous great white shark? It's too late to hunt it down, right?" Fang Youqun shouted immediately.
Xiang Yang glanced at Fang Youqun and said nothing.
Great white sharks are currently being protected in many countries and regions around the world.
Despite this, great white sharks are still regular victims of hunting.
On the black market, a great white shark tooth can be sold for at least tens of thousands of yuan.
"The great white shark is actually not as harmful to humans as the tiger shark." Chen Qingsheng suddenly said at this time.
"Yes, that's right." Xiang Yang nodded.
"The tiger shark is a big eater. It will not let go of any creature in its sight until it is full. The great white shark is different. Although the great white shark is greedy, it never eats too much."
The voracious tiger sharks will almost always catch all of their target food when foraging, and they even often kill each other for food.
When encountering a ship or a crashed plane, tiger sharks will swarm from all directions following the smell and devour the food in an instant.
But great white sharks are different.
Although great white sharks are also bloodthirsty, most of the time they will not take the initiative to attack.
Just one meal can keep great white sharks quiet and stop hunting for weeks.
During the few weeks when the great white shark is quiet, it will not be aggressive unless it is attacked.
A biologist once used a large amount of fish and meat mixed with blood as bait to lure full great white sharks. As a result, the great white sharks just swam around the food and did not bite it at all. Their usual ferociousness disappeared completely.
Of course, this doesn't mean that great white sharks are not scary.
No matter what, the great white shark's status as the top predator in the ocean remains unchanged. When hungry, the great white shark will eat anything it sees.
Once, when someone was dissecting a great white shark's stomach, they found a complete sea lion in it, which shows how big the great white shark's appetite is.
Moreover, the stomach of the great white shark has a very tough wall. Except for manta rays, swordfish and marlin, no matter how strange the object is, it will not hurt itself.
Because of this characteristic, many great white sharks accidentally swallow manta rays every year, and as a result, their abdomens are pierced from the inside out by the manta ray's stomach spines.
Xiang Yang and a group of crew members sat in the camp, commenting on the group of tiger sharks under the water.
Although tiger sharks are very ferocious marine predators, they are not patient marine predators. Therefore, Xiang Yang is not worried or afraid of the group of tiger sharks under the water.
As long as everyone stays away from the beach, these tiger sharks will leave on their own in no time.
And tiger sharks can't stay in sea ice areas for too long.
“Hoo, hoo.”
Just then, Xiang Yang suddenly heard a strange sound.
Xiang Yang quickly turned his head to look at the ice behind him.
After seeing it clearly, Xiang Yang burst out laughing, "It turned out to be an Antarctic sea wolf seal."
I saw that the Antarctic sea wolf seal was round and fat, shaped like a ball, with a head a bit like a dog. Its hind legs were lying on the ice with its front legs erect, trying hard to support its fat body.
"How did the Antarctic sea wolf seal get onto the ice?" Xia Pengjie asked in confusion. "As far as I can remember, this seal is a carnivorous marine animal that hunts, rests, and lives in the ocean."
"You're right, but that doesn't mean that Antarctic sea wolves and seals won't come to the ice. They just live in the sea most of the time. During the periods of molting, reproduction, and hiding from enemies, they will also crawl onto land or ice to live." Xiang Yang answered.
Xia Pengjie immediately showed an expression of understanding on his face. There were so many great white sharks under the sea. It seemed that this Antarctic sea wolf seal came to the ice to seek refuge.
Gao Chuang stared at the sea wolf and licked his lips. "It's really fat. If it weren't for the fact that it's an animal protected by the Antarctic Treaty, I would have to catch it."
When Xiang Yang heard this, he burst into laughter.
The Antarctic fur wolf seal is one of the six common seal species in Antarctica and is also the least numerous of the six seal species in Antarctica. It is extremely protected and if you kill an Antarctic fur wolf seal in Antarctica, you may be permanently expelled from Antarctica.
"Since this Antarctic sea wolf seal has been raised so fat, it seems that there are a lot of fishery resources under this sea area. How about we wait for blizzard to come and then cast a net nearby?" Xiang Yang asked.
Gao Chuang heard this and pondered for a moment.
Antarctic fur wolf seals mainly feed on various fish and cephalopods, and sometimes eat crustaceans. They have a huge appetite. An Antarctic fur wolf seal weighing about 70 kilograms needs to eat at least 7 kilograms of food a day to be full, and to satisfy their appetite, they may need 10 kilograms of food.
This Antarctic sea wolf seal has grown so fat, obviously there is no shortage of food under this sea.
"Not necessarily." Gao Chuang rubbed his frozen face. "Don't be fooled by its fat appearance. In fact, once it enters the water, it is extremely agile. It is too easy for them to catch fish. Whether there are many or few fishery resources under this sea area, we will know after we have fished there."
Xiang Yang nodded in agreement. The Antarctic sea wolf seal has a spindle-shaped body, smooth fur and streamlined body. It is a famous swimmer. It is said that its fastest swimming speed can reach 37 kilometers per hour.
Moreover, the Antarctic sea wolf seal not only swims fast, it is also particularly good at diving.
According to Xiang Yang, the Antarctic fur wolf seal is the seal with the second-best diving ability among the six common seals in Antarctica, after the Weddell seal.
With their superb swimming skills and powerful diving abilities, it is very easy for Antarctic sea wolves and seals to hunt.
Moreover, Antarctic sea wolf seals can quickly change their swimming direction in the water and quickly chase swimming prey.
In addition, the Antarctic sea wolf seal has a strong jaw with extremely sharp teeth that can even compete with tiger sharks. Once a prey is bitten by an Antarctic sea wolf seal, there is basically no chance of survival.
With its first-class swimming skills and sharp teeth, the Antarctic sea wolf seal is definitely the top marine predator in the entire Antarctic.
