My Deep-sea Fishery

"Look at that." Xiang Yang pointed to the sea wolf seal and said.

A group of people looked over there, and saw the sea wolf seal staring at a sea gull ready to move.

It crawled on the ground, a little closer.

As a result, before it launched an attack, the seagull realized something was wrong, flapped its wings and flew towards the sky.

The sea wolf seal immediately rushed forward angrily, but in the end it only jumped into the air. It could only growl, and then shifted its target unwillingly, and stared at an unlucky seabird that had died of breath.

"Captain, please ignore that sea wolf and seal for now, and look at the surface of the sea." Chen Qingsheng said at this time.

"Sea surface?"

Xiang Yang turned his head and looked towards the sea.

I saw the silver light on the surface of the sea, refracting light everywhere, obviously, fish schools appeared under the water.

But Xiang Yang was not moved, "Looking at the refraction of the light, it should be krill."

"Well, wait, it seems to be a cross jellyfish." When Xiang Yang was on the brick, he suddenly saw an orange in the water, like an umbrella, and countless filamentous creatures floating under the umbrella.

The cross jellyfish looks soft as silk and looks beautiful and docile, but in fact it is an extremely cold ocean killer.

However, compared with the transparent body of ordinary jellyfish, this jellyfish has a color on its body, which is very conspicuous when Yuge is in the sea, and will not let fishermen be caught unconsciously when fishing on the bottom of the sea.

"It seems to be really a cross jellyfish." At this time, Gao Chuang said solemnly.

Although the cross jellyfish has a colored body and cannot approach its prey silently, its predation technology is very superb. They use ancient predation methods to forage by drifting. Creatures like krill suck their own swirling hunting grounds.

When the prey arrives at the vortex hunting ground, the cross jellyfish can use the tentacles to send the food to its mouth and wrist, and then use the umbrella to digest the food.

"Brother Yang, do you think these humpback whales are in danger?" Fang Youqun asked worriedly.

Xiang Yang frowned. Ordinary jellyfish, even if they were highly poisonous, would not have much effect on whales with rough skin and thick flesh.

But the cross jellyfish is different.

The cross jellyfish's tentacles are very long, and the longest tentacles can even reach tens of meters. In addition, they are highly toxic. If the number is sufficient, it may really affect the whales.

"Don't be afraid, these whales didn't move, which proves that these jellyfish should not be able to threaten them." Xiang Yang said softly.

Fang Youqun breathed a sigh of relief when he heard it, and turned to observe the cross jellyfish carefully.

Seriously, this cross jellyfish is really pretty when swimming in the sea.

On the umbrella-shaped body of this cross jellyfish, there are beautiful patterns composed of various colors.

When the cross jellyfish floats freely in the clear ice water, it is as gorgeous as fireworks and very beautiful.

Xiang Yang also noticed that this cross jellyfish not only has a variety of colors, but also emits stronger or weaker purple halos on its umbrella body. When it swims, it looks like a dazzling colorful ball. For a long time, Xiang Yang was a little dumbfounded.

It's really beautiful.

Of course, Xiang Yang was standing by the ice floe on the shore.

If it was at the bottom of the water, Xiang Yang would definitely hide as far as he saw this cross jellyfish.

Because under the beautiful appearance of the cross jellyfish, there is actually a terrifying murderous intent.

The luminescent cross jellyfish can often use lights to attract many marine creatures to come and watch.

As everyone knows, this beautiful light is actually one of the methods used by cross jellyfish to prey.

Relying on the beautiful halo on its body, the cross jellyfish can often attract a lot of prey into its hunting range, and then take the opportunity to attack and have a full meal without any effort.

"It's not a good thing to meet jellyfish." Gao Chuang rubbed his eyes, feeling a little unlucky.

Xiang Yang smiled, "But there is no way, jellyfish are not so easy to destroy, the vitality of this thing is too strong."

After Fang Youqun heard this, he was very puzzled and said, "It's not easy to destroy? Isn't this just a jellyfish? Let me fish it up and it's over?"

Xiang Yang rolled his eyes, "There are only jellyfish and there are no jellyfish, there are no few or many. Since there are jellyfish in this sea area, it proves that there are jellyfish in this sea area. What's the use of you fishing for this one?"

The lifespan of cross jellyfish is very short, only about two months on average.

If you don't fish it, it won't live long.

Even if it is caught, it will not change the fact that there are jellyfish 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 dinosaurs.

Even time cannot destroy them, and it is too difficult to destroy them by manpower.

Even jellyfish were once doubted whether they belonged to animals.

Although jellyfish are carnivorous animals that mainly feed on fish and plankton, jellyfish do not have respiratory organs and circulatory systems, only the most primitive digestive organs, so they are not animals at all.

After research, biologists found that the food captured by jellyfish will release digestive juice through the stinging cells on the gastric wire in the stomach cavity, and then be digested and absorbed in the coelenterate immediately.

Moreover, most jellyfish are very greedy. Whether it is facing various plankton, crustaceans, or fish eggs, big fish or small fish, jellyfish will always absorb them and directly absorb them.

And it may be the reason why jellyfish only have primitive digestive organs, so jellyfish eat very fast, even if they digest a complete fish, it only takes a few hours, and the digested and absorbed substances are quickly passed through the intestinal cavity to carry out substances transportation.

It is this almost terrifying absorption ability that makes jellyfish have to eat a lot of food every day to maintain their own life characteristics.

Therefore, all fishermen, including those engaged in aquaculture, hate jellyfish very much.

Ignore these jellyfish, they will reproduce in large numbers in the sea area, wipe out all the fish, shrimp, crab, even plankton and fish eggs in the nearby sea area, and completely deplete the fishery resources in the entire sea area.

If you ignore them, you might get stung by this thing instead.

In many fishing villages, there are staff who specialize in catching jellyfish. They usually work in groups of two, one person rowing a small boat, and the other uses a hook to hook all the jellyfish encountered onto the small boat, and then put those All jellyfish were transported to shore for disposal.

Their wages are borne by nearby fishermen. This is a very dangerous job. Whether it is a boater or a jellyfish catcher, they will often be stung by jellyfish.
