"Look at that." Xiang Yang pointed at the sea wolf seal and said.
A group of people looked over there and saw the sea wolf seal staring at a large seagull, ready to make a move.
It crawled on the ground and moved closer little by little.
As a result, before it could launch an attack, the seagull noticed something was wrong and flapped its wings to fly high into the sky.
The sea wolf seal immediately pounced forward angrily, but it only pounced on the air. It could only roar, and then unwillingly changed its target and stared at an unfortunate seabird that had already died.
"Captain, don't pay attention to the sea wolf seal for now, just look at the sea." Chen Qingsheng said at this time.
"On the sea?"
Xiang Yang turned his head and looked towards the sea.
I saw silver light flashing on the sea surface, reflecting light everywhere. Obviously, there were schools of fish under the water.
But Xiang Yang was not moved. "Looking at the refraction of light, it should be krill."
"Hmm, wait, it looks like a cross jellyfish." When Xiang Yang was looking at the bricks, he suddenly saw an orange-yellow color in the water, like an umbrella, with countless filamentous creatures floating under the umbrella.
The cross jellyfish has a soft, silky appearance and looks beautiful and docile, but it is actually an extremely ruthless ocean killer.
However, compared with the transparent body of ordinary jellyfish, this jellyfish has color on its body, which makes it very conspicuous when swimming in the sea, and will not cause fishermen to be caught unknowingly when fishing on the seabed.
"It seems to be a cross jellyfish." At this time, Gao Chuang said with a serious expression.
Although the cross jellyfish has a colored body and cannot approach its prey silently, its hunting technique is very advanced. It uses an ancient hunting method and uses drifting to find food. By generating electric currents, it creates small whirlpools in the water, sucking large numbers of creatures such as krill into its whirlpool hunting grounds.
When the prey arrives at the vortex hunting ground, the cross jellyfish can use its tentacles to deliver the food to its oral arms, and then use its umbrella to digest the food.
"Brother Yang, do you think these humpback whales will be in danger?" Fang Youqun said worriedly.
Xiang Yang frowned. Even if ordinary jellyfish are highly poisonous, they will definitely not have much impact on the thick-skinned whales.
But the cross jellyfish is different.
The tentacles of the cross jellyfish are very long, with the longest tentacle reaching dozens of meters. In addition, their venom is extremely potent. If there are enough of them, they may really have an impact on whales.
"Don't be afraid. These whales haven't moved, which proves that these jellyfish shouldn't be a threat to them." Xiang Yang said softly.
Upon hearing this, Fang Youqun immediately breathed a sigh of relief and turned to carefully observe the cross jellyfish.
To be honest, this cross jellyfish is really beautiful when it swims in the sea.
On the umbrella-shaped body of this cross jellyfish, there is a beautiful pattern composed of various colors.
When this cross jellyfish floats and sinks freely in the clear icy water, it looks as gorgeous as fireworks and is very beautiful.
Xiang Yang also noticed that this cross jellyfish not only had a variety of colors, but also emitted a strong or weak purple halo from its umbrella-shaped body. When it swam, it looked like a dazzling colorful ball. For a moment, Xiang Yang was stunned.
It’s really so beautiful.
Of course, Xiang Yang was just standing on the ice floe on the shore.
If Xiang Yang saw this cross jellyfish under the water, he would definitely run as far away from it as possible.
Because beneath the beautiful appearance of the cross jellyfish, it actually contains terrifying murderous intent.
The luminous cross jellyfish can often use lights to attract many marine creatures to come and watch.
Little do people know that this beautiful light is actually one of the means by which the cross jellyfish hunts.
With the beautiful halo on its body, the cross jellyfish can often attract many prey into its hunting range, and then it will take the opportunity to attack and have a full meal without any effort.
"It's not a good thing to encounter jellyfish." Gao Chuang touched his eyes and said unhappily.
Xiang Yang smiled and said, "But there is no other way. Jellyfish are not so easy to kill. They have too strong vitality."
After hearing this, Fang Youqun was very puzzled and asked, "Isn't it difficult to kill? Isn't it just a jellyfish? Can't I just catch it?"
Xiang Yang rolled his eyes. "There are only jellyfish or no jellyfish, not a few or a lot of them. Since jellyfish have appeared in this sea area, it proves that there are jellyfish in this sea area. What's the point of you catching this one?"
The life span of the cross jellyfish is very short, only about two months on average.
If you don't fish it out, it won't live long.
Even if they are caught, it cannot change the fact that jellyfish appear in this sea area.
In addition, the cross jellyfish is a very ancient creature, its origin can be traced back to 600 million years ago, and it has existed on this planet longer than the dinosaurs.
Even time cannot eliminate them, and it is too difficult to eliminate them by human power.
There was even a time when people doubted whether jellyfish were animals.
Although jellyfish are carnivorous animals that mainly feed on fish and plankton, they have no respiratory organs or circulatory systems, only the most primitive digestive organs, and cannot be considered animals at all.
After research, biologists found that the food caught by jellyfish will release digestive juices through the stinging cells on the gastric filaments in the stomach cavity, and then be immediately digested and absorbed in the coelenteron.
Moreover, most jellyfish are very greedy. No matter whether they are facing various plankton, crustaceans, fish eggs, big fish or small fish, jellyfish will accept them all and absorb them directly.
It may be because jellyfish only have primitive digestive organs, so they eat very quickly. Even if it is a whole fish, it only takes a few hours, and the digested and absorbed substances are quickly transported through the intestinal cavity.
It is this almost terrifying absorption ability that requires jellyfish to eat large amounts of food every day in order to maintain their life characteristics.
Therefore, all fishermen, including those engaged in aquaculture, hate jellyfish very much.
If these jellyfish are ignored, they will multiply in large numbers in the sea, destroying all the fish, shrimps, crabs and even plankton and fish eggs in the nearby sea, completely depleting the fishery resources in the entire sea area.
If you pay attention to them, you might end up getting stung by them.
In many fishing villages, there are staff members who specialize in catching jellyfish. They usually work in groups of two. One person rows a small boat, and the other uses a hook to hook all the jellyfish they encounter onto the boat. Then they transport all the jellyfish to the shore for disposal.
Their wages are shared by nearby fishermen. This is a very dangerous job. Both rowers and jellyfish collectors are often stung by jellyfish.
