Treasure Hunt Tycoon

It's a wonderful feeling to float on the Antarctic sea.

Li Du squatted in front of the ice boat. When the wind blew, the canvas hunted and the sound came out. The water surface was rippling with waves. The wind and waves pushed the ice boat forward.

But regardless of the strong wind and small wind, the boat is very stable and has always been very stable.

The volume of ice under the water is too large, which ensures that the ice boat has a particularly good stability. This is one of the reasons why people choose to build ships with ice in Antarctica.

Some seagulls flew over their heads. Their bodies were more than half a meter long and had white tails, but their bodies were hazel and they didn't look very beautiful.

After flying several times, a seagull thief's head and head looked at the boat a few times, and suddenly flew down to catch the strap of a kettle on the boat.

The blue-and-white strap is blown by the wind and may look like a sea fish.

A Mei next to her eyes narrowed, and her claws suddenly stretched out. She slapped the seagull into the sea and tore off a few feathers.

The seagull soon got out of the sea and spread its wings again. It looked embarrassed. It still flew around the boat in the back.

Sophie raised her camera and took a few photos, saying, "These skuas are really daring."

This is a skua, not an ordinary seagull. As the name indicates, they are predatory. The emperor penguins were forced to lay their eggs in winter because of them.

Skua like to steal penguin eggs. Most penguins lay their eggs twice a year, and they can lay three or four eggs. Emperor penguins lay eggs once a year, almost all of them lay eggs.

In order to protect their offspring, they had to lay their eggs in winter and hatch successfully in summer, because the Antarctic was too cold in winter and the skua went north to overwinter.

The ice boat is wandering in the Antarctic Sea. There are only ice fields and pieces of ice floating around. Sea birds fly overhead. There are fat penguins in the water and on the ground. Everything is quiet and comfortable.

A water splash suddenly burst out, and then a sea lion came out of the water to probe.

This animal has a huge body, looks fat and stupid like emperor penguins, but it is only for their terrestrial performance. They are definitely worthy of their names in the ocean: fierce like a lion, strong like a lion!

Steve specifically reminded them: "Don't mess with the sea lions, they're not easy to mess with, these grumpy guys can be terrible to start a fire."

As he said, he opened a box with some herring in it. He picked up one and threw it away, and the sea lion swam past when he noticed it.

The skua also noticed that these guys were bold and swiftly divided into two paths, all the way to chase the herring that fell into the sea, and the other way directly to Steve to grab the fish.

Steve's bodyguard waved his arm to drive away the skua. In the distance, the sea lion was also competing with the skua, but it was not so gentle. It jumped out of the water and opened its mouth to bite a skua and drag it. Into the water.

The skua did not fly again.

Not to mention that it didn't fly, most of the other skuas that got into the sea didn't fly. Several sea lions came out from behind, and their mouths kept chewing. Apparently, the skua became their food.

Steve laughed: "Ha, I'm lucky, that herring was thrown into the habitat of a sea lion."

The two ice boats were floating one after the other, and Steve had not been off the net, and no krill had been found.

Li Du is no longer obsessed with fishing for shrimps at this time. He sits cross-legged on the bow of the boat and enjoys the tranquility that is rare in other places.

Suddenly, he noticed that the color of the sea water under the boat changed, and the blue water turned light brown!

This light brown current appeared abruptly. He thought he had encountered a strange undercurrent. At this time, Steve shouted, "Shrimp!"

Hearing what he said, Li Du suddenly understood: They met the krill group!

Krills like to swim in groups. A population that floats on the surface of the water can cover a marine area that is hundreds of meters long and wide. Their population density is very high. There are 30,000 to 40,000 krill per cubic meter of water, which makes the seawater also serve it. Discoloration.

Li Du asked: "This is the shrimp that caused the sea water to turn brown? Aren't they transparent? How could it be brown?"

"Their body is transparent to our eyes, but it is not completely transparent to daylight. There are too many krill, which prevents the light from penetrating the seawater and becomes this color." Steve explained.

Then, he shook his head with regret: "It is a pity that it is extremely day. If it is at night, you can see a beautiful world. This ocean will become green fluorescent! The fluorescent color of krill is beautiful!"

When they meet the shrimp group, they can go off the net.

Krill mate in the Antarctic in spring, from October to November, and in the summer, they will emerge in groups and spawn in large numbers.

The interesting thing is that females spawn multiple times in a few days, rather than spawning all the eggs at once.

Once these shrimp eggs leave the mother body, they will immediately sink to the bottom of the sea a few hundred meters deep, where they hatch into larvae, and survive on the yolk stored in the yolk sac in the eggs.

After eating the yolk, they will float to the surface of the sea to take in phytoplankton.

So in this way the net is netted ~ www.wuxiaspot.com ~ and all the adult krill are caught. However, the adult krill is not large, and the sea water is very cold. They grow very slowly, and can grow up to five or six centimeters in length.

The two boats each dropped a small net, and then they could immediately retract.

Li Du and the wolf brother pulled their heads together to make an effort to close the net.

This is a throwing net that is simple to use and can only catch small fish on the water. It is usually of little use, but here it is very useful, especially suitable for catching krill.

As the fishing nets were pulled up, a large pile of krill appeared.

After landing on the boat, these krills bounced, and the vitality was called a tenacious.

"Return immediately," Steve said. "Don't pull them up, soak them in water, and pull them up again when you're ashore."

Krill's digestive tube is very simple. The branched liver and pancreas are digestive glands. Their shell and meat are transparent. You can see the internal organs, especially the green digestive tube.

The digestive glands are well developed, and krill can secrete a large amount of digestive enzymes. If they die, the digestive enzymes will still be active and they will digest the proteins in their bodies.

That's why Steve won't let them pull up their fishing nets, and try to keep the krill vital.

Brother Lang grabbed a handful of krill from the fishing net, just like a snack, stuffed it into his mouth and ate a few.

Li Du also took one to eat. The environment in which krill lives is pure and natural, and there is no heavy metal elements. They eat green seaweed and copepods, amphipods and other small zooplankton.

Shrimp is cold and flexible, with a sweet flavor, without any fishy smell, and it looks like a snack in the mouth.

Li Du ate two and stuffed it to A Meow. A Meow was very happy. He grabbed shrimp from his net with his paw and ate it.
