In addition, Xiang Yang also discovered that the two nostrils of that group of hammerhead sharks were actually far apart.
Xiang Yang stared carefully at a hammerhead shark with a white belly and a brown-red back, and found that its two nostrils were located on both sides of its head.
It is said that the nostrils of hammerhead sharks, located on both sides of their heads, are far apart, so they can better identify smells from farther away.
The nostrils play an important role in the hammerhead shark's hunting process.
The hammerhead shark's bizarre appearance and supernatural sixth sense are simply designed for hunting.
Some biologists have concluded that it is the hammerhead shark's voracious eating habits that have caused the hammerhead shark to evolve into this peculiar appearance during the long process of foraging, to help the hammerhead shark hunt for food.
Xiang Yang also agreed with this inference.
Because sharks have existed on Earth 400 million years ago, they have existed on this planet longer than the dinosaurs.
However, the hammerhead shark evolved only about 50 million years ago and is definitely a new member of the entire shark family.
According to the theory of evolution of survival of the fittest, it is almost impossible for hammerhead sharks to evolve into their current form without special reasons.
While Xiang Yang was looking at the hammerhead sharks, the hammerhead sharks were also looking at Xiang Yang.
The two eyes of the hammerhead shark are located at the two ends of the protruding parts on both sides of the head, and the distance between the two eyes is one meter. This special eye layout not only gives the hammerhead shark binocular vision like humans, but also allows the field of vision of the two eyes to overlap. It can also see the scenes in all directions at the same time by swinging its head back and forth.
The hammerhead shark relies on its extraordinary binocular vision to catch and avoid danger.
Relying on a pair of eyes that are far apart, the hammerhead shark can accurately judge the distance and speed of its prey when it appears, and then quickly launch an attack to kill the prey.
When a hammerhead shark swims back and forth in the ocean, its swaying head allows it to observe the surrounding situation at any time, detect potential dangers and enemies at the first time, and quickly avoid danger.
It might be because the hammerhead sharks had never seen a creature like Xiang Yang before, or it might be because Xiang Yang and his group were so numerous that their numbers far outnumbered those of the hammerhead sharks, or it might be a combination of these two reasons. In short, these hammerhead sharks were very wary of Xiang Yang.
Xiang Yang didn't feel surprised at all.
Animals are always wary of unfamiliar creatures, even sharks are no exception.
Xiang Yang felt relieved when he knew that the hammerhead sharks were observing him.
Xiang Yang just smiled slightly, flashed under the sea, and appeared several hundred meters away.
Sure enough, the hammerhead sharks immediately became agitated. If Xiang Yang had not been swimming towards those hammerhead sharks, they might have been frightened and fled.
Xiang Yang knew that the trajectory of his swimming just now was definitely seen by those hammerhead sharks.
Scientists have discovered that the wider the hammerhead shark's head is, the greater the overlap of its visual fields, and the wider and clearer the field of vision it can detect.
Xiang Yang swam quickly and continuously on the seabed for several times, and then stopped more than a hundred meters away from the hammerhead sharks, with the corners of his mouth slightly raised. Such a fast swimming speed should have scared the hammerhead sharks, right
However, swimming fast does not mean being aggressive.
But in the ocean, swimming faster often means more danger.
Sure enough, when Xiang Yang looked at the group of hammerhead sharks again, they were no longer staying in place to feed on krill, but began to sink to deeper waters.
Xiang Yang immediately grinned. As long as these hammerhead sharks didn't attack him and his crew, Xiang Yang didn't care where these hammerhead sharks went.
By the way, hammerhead shark is also the number one swimmer in the ocean.
Hammerhead sharks are migratory fish. Every year, they travel in groups on a long journey. In summer, they swim to the south of the South Pacific to escape the heat. In winter, they swim to temperate and tropical waters to avoid the winter.
However, this is not absolute.
After research, scientists discovered that there are many lone sharks in the hammerhead shark family that do not participate in migration. Except when hunting, they will act together with other hammerhead sharks. Most of the time, they are alone in the ocean.
Hammerhead sharks have a very strong ability to adapt to their environment.
Hammerhead sharks can be found from tropical beaches with temperatures of dozens of degrees to waters thousands of meters below the sea with temperatures of minus degrees Celsius.
And like most sharks, hammerhead sharks have no lungs, breathe through gills, and do not need to sleep.
Hammerhead sharks cannot stop swimming. If they stop swimming, they will immediately sink to the bottom of the sea.
After the group of hammerhead sharks swam into deeper waters, Xiang Yang stood there and watched for a while.
Although, among the sharks that threaten humans, there is no hammerhead shark.
For a long time, hammerhead sharks were considered to be terrifying man-eating sharks.
However, after field investigations by scientists and biologists, it was discovered that hammerhead sharks are actually different from great white sharks and tiger sharks.
Although hammerhead sharks are brutal, they are very docile towards humans. Most of the time, hammerhead sharks will not attack humans. Only when they are attacked by humans will the frightened hammerhead sharks take extreme actions to hurt people.
But when Xiang Yang really faced these hammerhead sharks, he still did not dare to allow these hammerhead sharks to swim in the same waters with his crew.
There are so many freaks among humans.
What if one of these hammerhead sharks is a freak that isn’t kind to humans
Moreover, the crew members who got on and off Xiang Yang's ship were all carrying biological electric guns.
Let these hammerhead sharks swim close to the crew. Xiang Yang doesn't believe that no one will use the biological electric gun.
As long as one crew member was injured by these hammerhead sharks, it would be a serious accident for Xiang Yang, so Xiang Yang didn't dare to let these hammerhead sharks meet the crew members.
Xiang Yang stayed there for five minutes. After making sure that the hammerhead sharks had disappeared from the sea and would no longer appear in his sight, Xiang Yang slowly breathed a sigh of relief.
After what these hammerhead sharks did, Xiang Yang was no longer in the mood to continue fishing for ice algae in this area.
Xiang Yang looked at the net bag around his waist. Inside was a small bag of ice algae, which was enough for Xiang Yang to eat for several meals.
Xiang Yang simply waved his hands and swam towards the top of an underwater mountain.
Xiang Yang planned to find a few more green-lipped abalone and then go back to the boat directly, and the crew would not be allowed to disembark for a short period of time.
