Chapter 1319 Gorgeous Seabed Scenery

"Chao Gang, shall we dive now? I really don't want to dive anymore, shall we just stay here like this?"

Liu Jingjing was lazily lying in Zhao Chaogang's arms. She just wanted to stay in Zhao Chaogang's arms and enjoy the warmth that only belonged to her. As for things like diving, Liu Jingjing didn't want to at all now.

For a girl of her age, enjoying the love with her lover is more important than anything else.

"Hehe, how can this work." Zhao Chaogang gently helped Liu Jingjing to stand upright, and Pingping was still watching here on the other side. If he was just on the beach, holding Jingjing to enjoy two In the human world, isn't this too unfair to Pingping.How could Zhao Chaogang do such an outrageous thing, so even if Liu Jingjing made this request, Zhao Chaogang still refused.

Of course, Zhao Chaogang will not be like those macho people. When making a decision, he is very arrogant and does not consider other people's feelings at all. After Zhao Chaogang made this decision, he quickly told Liu Jingjing explained: "Jingjing, it's not just the two of us here, Pingping is still watching us on the beach. If Pingping's body is not suitable for diving, Pingping will definitely be with us now, so you say If we just stay on the beach like this, enjoying the two-person world alone, is it fair to Pingping on the beach? !

Jingjing, when you wanted to go diving in the sea with me, Pingping agreed very generously, so.Jingjing, you can't do things according to your own temperament. "

"Hmm..." Liu Jingjing's face was very embarrassed when Zhao Chaogang said it, and she quickly realized it.Her behavior just now was indeed a bit selfish. She just considered her own feelings and didn't think about other things at all. When she recalled Sister Pingping's generosity, Liu Jingjing would of course feel very embarrassed.

"Okay, okay, Jingjing, you just need to know that you are wrong. There are no outsiders here, so it's okay."

Zhao Chaogang released Liu Jingjing leniently, and the three of them got along.The difficulty and trouble are not small, but Zhao Chaogang chose this by himself, so Zhao Chaogang can only bite the bullet and deal with all the problems between the three of them.

"Yeah. Chao Gang. Then let's dive into the water!" Liu Jingjing's face is flushed now, so she desperately wants to dive directly into the sea water. In this way, the embarrassment she just had just disappeared, so Liu Jingjing now I was eager to dive in.

This is tantamount to deception, which made Zhao Chaogang on the side almost laugh.

certainly.Zhao Chaogang still said that now is not the time for him to laugh, if he hadn't really laughed at this time.The result...Zhao Chaogang shivered all over, he didn't want the flesh on his ribs to turn black and blue.

Jingjing's pinching skill is absolutely powerful!

"Okay, then we will start diving." After Zhao Chaogang said this, he began to bring the tools needed for diving to the two of them.

The waves on the beach are very big. If you want to dive directly into the sea from the beach, it is really very difficult without hard training.

Here on the beach, once you go into the sea, the waves of the waves will keep hitting you, making it difficult for you to swim towards the distant sea. Moreover, even if you overcome the constant impact of the waves on you, your At this time, the physical strength has been consumed a lot, and it is impossible to go diving in the sea.

Therefore, when other people dive in shallow seas, the diving nurses use boats to send them to the surface of the sea, and then bring some special diving equipment, such as respirators, diving suits, etc., into the water. , in this case, it is more secure.

However, these difficulties are not a problem for Zhao Chaogang and Liu Jingjing at all. It is really not qualified for mere waves to cause trouble for them.

"Okay, the respirator is ready, Jingjing, let's go into the water!" Zhao Chaogang gently helped Liu Jingjing put on the respirator. Of course, it is a very simple one, not those professional diving utensils.

Breathing in the ocean is actually not a problem for cultivators like Zhao Chaogang and Liu Jingjing. Now Zhao Chaogang brings a simple diving respirator to Liu Jingjing just to let Liu Jingjing get used to it in the sea. the process of.

After Liu Jingjing became a cultivator, she had never dived in the sea, so it was still a little difficult for her to let go of her scuba diving device and go diving in the sea. That's why Zhao Chaogang brought it to Liu Jingjing. Recommended scuba rebreather.

After Liu Jingjing got used to the sea, Zhao Chaogang would take off this simple diving respirator.Diving in the sea, the feeling of not having a diving respirator and wearing a diving respirator are completely two concepts.

"Well, Chao Gang, let's go into the water!" Liu Jingjing took Zhao Chaogang's hand and began to walk slowly into the sea.When he was about to enter the water, Zhao Chaogang gestured an 'ok' gesture to Li Liping in the distance, and then directly followed Liu Jingjing, diving into the sea water, and the diving journey of Zhao Chaogang and Liu Jingjing began.

The shallow sea is a colorful world, where creatures bathe in bright and warm sea water; wonderful small fish roam among the gorgeous corals, and strange and lovely shellfish, starfish, jellyfish and seaweeds of various colors flutter under the surging waves Dance to form a beautiful picture.

The sun shines on the quiet seabed, as if the light is analyzed by twists and turns through the spectrum, which is too beautiful to behold.Even the rocks, vegetation, shells and corals on the bottom of the sea are also dyed with colorful sunlight, which is surprising.

Plants on land include trees and flowers, which form large forests, grasslands or garden green spaces.Plants in the ocean are called seaweeds, and some seaweeds are so small that they can only be seen by magnifying them dozens or hundreds of times with a microscope.They are composed of single cells or clusters of cells, with branches and leaves of different colors, and they float in the water against the branches and leaves.

Single-celled seagrass grows and reproduces rapidly, multiplying many times in a day.Although.They are constantly devoured by various fish and shrimp, but the numbers are still very large.

Large seaweeds are tens of meters or even hundreds of meters long, and their soft bodies cling to the bottom of the sea.It is rocked back and forth by the waves, but it is not easily broken.All kinds of shells and molluscs walk on the soft sand, making the seabed look like a garden.All kinds of jellyfish float above the head, just like the blossoming flowers scattered by fairies.

Such a beautiful scenery, of course, made Liu Jingjing intoxicated by it. When facing such a beautiful thing, a woman is the least resistant.

"Chao Gang. Look, look, what a big turtle!" At this time, Liu Jingjing was no longer wearing a simple diving respirator.After a few minutes of adaptation, now Liu Jingjing can swim freely in the sea like a fish.

A cultivator has sufficient lung capacity, and there are some small spells that can extract oxygen from sea water.Let the practitioners survive in the ocean for a long time.

"Hehe. Really, this turtle is really big. It's really rare to see such a big turtle!" Zhao Chaogang also sighed like this, all because of the size of the turtle in front of them It was really huge, as big as two small cars, Zhao Chaogang and Liu Jingjing had never seen such a big turtle.

Unfortunately.This turtle is a bit big, however.This turtle is just an ordinary turtle, it has not yet become a savage beast, such a turtle can only make Zhao Chaogang and Liu Jingjing sigh, and there is nothing else to suppress.

"Coral, Chao Gang, look quickly, it's red coral...! It's such a big piece! Chao Gang, let's go over and have a look, I like red coral the most."

"Okay, okay, let's go now, Jingjing, don't worry!"

Soon, Zhao Chaogang and Liu Jingjing came to the place where the red coral was located. As soon as they arrived here, Zhao Chaogang and Liu Jingjing were attracted by the fiery red in front of them. This is a piece of red coral, an extremely dazzling red coral.

Red coral (scientific name: corallium milk b milk m) lives in groups. ~2cm, each individual has 8 feathery tentacles.Diaphragms 8 unpaired, diaphragm muscles grow ventrally, septum filaments are single-lobed.There is only one mouth groove, which is located on the ventral surface.

Red coral skeletons are mostly in the body, or extend from the body to the body surface.It has a calcareous axial bone, which is branched like a tree, but not on one plane, and the bones are pale pink to dark red.

In addition to the axial bone, there are calcareous spicules distributed in the middle glue layer, and they often live together with reef-building corals.The bones are dense in texture and bright in color. They are often used as gemstones or carving materials. They grow in the equator and nearby tropical and subtropical regions where the temperature is higher than 20c.

The pilgrimage beads of ancient Chinese emperors are made of red coral; they can also be used as medicine, which has the effect of calming shock and improving eyesight.Due to a large number of mining, the number has decreased sharply, and it is listed as a first-class protected animal in China.

Red coral Red coral is a polyp-type group animal, a coral individual that lives in groups.The skeleton of red coral is a dendritic complex.There is a horny skeletal shaft in the center of each branch, and the soft body surrounds the skeleton, and many polyps grow around the shaft.These cylindrical shafts are up to 20 cm high and 3 cm in diameter.

The soft body of the red coral polyp has a mesoderm, an endoderm and an ectoderm.Red coral polyps secrete skeletons through the ectoderm - red corals.Rigid colonies grow in all directions on the pedestal, creating a furry shape.There are short hemispherical calyxes distributed on the branches, and the polyps that expand at the base are white and transparent, with eight small pinnae with good antennae.

Once the coral is touched, the polyps retract within the cup.Calcareous spicules and ossicles on columnar branches, radially symmetrical, warts short rod-shaped.The color is usually dark red.

The red coral body is columnar, and the length of the column varies with the species and living environment. The body is fixed on rocks, sandy bottoms, shells or other objects with a substrate.The free end is the mouth end, and the mouth end expands outwards to form a mouth plate, and there are one or more circles of tentacles around the mouth plate, and the tentacles are hollow.

Eight coral tentacles each have 8 feathers, that is, each tentacle extends out to both sides in rows of small protrusions.

The structure of the gastric cavity of coralline animals is also more complex than that of hydrozoans, that is, the endoderm of the body wall extends sequentially to the gastric cavity to form many septa, which divide the gastric cavity into many small chambers to increase the surface area of ​​the gastric cavity, such as octave Coral has 8 diaphragms, the upper end of which is connected to the mouth canal. The histological structure of the septum is composed of two layers of endoderm cells with a middle glue layer in the middle. The inner end of the primary septum is connected to the endoderm of the mouth canal.The inner ends of the septum of other grades are free, and the septum at the free end expands to form a trilobal shape, which is called septal filament (me color nte alfilament).

There are a large number of cilia on the surface of the cells on the two lateral lobes of the septal filaments.The shaking of cilia is beneficial to the circulation of liquid in the gastric cavity, and there are a large number of cnidocytes and glandular cells distributed on the middle lobe, so the cnidarian cells in the gastric cavity of Coryneta are of endoderm origin.

Gland cells secrete digestive enzymes for food digestion.The septal filaments of octocorals have only middle lobes and no lateral lobes.

The septum filament is generally longer than the septum, and the end is free in the gastric cavity or wrapped around the bottom of the gastric cavity, called the acontium, and sometimes it can protrude from the body wall or from the mouth to assist in predation.

The muscles in coralline animals are more developed than those in hydrozoans.The myofibrils in the dermatomyosus cells possessed by Hydra no longer exist, and instead, the endoderm produces independent muscle bundles.Distributed on the diaphragm or in the middle layer.Well-developed muscle bundles allow the body to lengthen or shorten, and retract the tentacles into the stomach cavity.

The longitudinal muscle bundles on the diaphragm of Octocora are all arranged ventrally, and the circular muscles of the body wall are also generated from the endoderm.Especially developed at the mouth plate.

The neural structure of coralline is also the nerve plexus that forms the epithelial nerve plexus and gastric layer, but it has more bipolar neurons and synaptic conduction, so the response is faster than that of hydrozoans.

No special senses.Most coralline animals are dioecious.The gonads are located on the septum, forming a long ribbon between the longitudinal muscle bundle and the septum filaments. The germ cells are derived from the mesenchymal cells of the endoderm, but the general situation points to the infertility of the septum.

If it is a hermaphroditic species, it is generally protandry to avoid homozygous fertilization.The germ cells are excreted and fertilized in seawater, or in the gastric cavity.During development, it passes through floating larvae and then develops into an adult.

Red corals grow in tropical and subtropical regions near the equator where the temperature is higher than 20C.In the calm and clear rock reefs, platforms, slopes, cliff faces, and grooves with a water depth of 20-200 meters.

Temperature is the limiting factor affecting the growth of reef-building corals. Only when the annual average temperature of seawater is not lower than 20C can corals build reefs. The optimum temperature range is 22-28C.

It mainly lives in shallow seas, around continental shelves and islands, its vertical distribution is limited to within 60 meters, and it grows best at a depth of about 30 meters.

Because the shallow sea area is the penetrating layer of sunlight, which is conducive to the photosynthesis of the symbiotic algae in the coral body. The shallow sea area provides a rich food source and sufficient oxygen for the coral due to tidal action, wind, waves, and seawater vibration, and it is easy to remove metabolites. .

Red corals live in relatively clean seawater. If too much terrestrial matter pollutes seawater, it will inhibit the normal physiological functions of corals such as feeding and respiration. That is to say, they require to live in seawater with standard salinity range, that is, every day A liter of seawater contains 35g of salt, and the terrigenous substances in the polluted seawater will also reduce the salinity of the seawater.

Habitat conditions required for the growth of red corals, they require hard bottom, fast flow, no sediment (especially no terrestrial sediments), clear water, low light, low temperature (8 ~ 20c), among which the Mediterranean red coral field is the most suitable The temperature is 10c.

Red coral grows slowly and has a long lifespan. It is only 10 to 12 years after the larvae attach to sexual maturity. It lays eggs every summer, and its floating larvae are negative phototaxis.Because red corals live longer than other invertebrates, their slow growth rate and low adult mortality are inevitable trends.

Red coral is also a very famous gemstone. Red coral is an organic gemstone with pleasing color and lustrous texture. This kind of red coral grows in the deep sea 100 to 2000 meters away from human beings.Along with pearls and amber, it is listed as the three organic gemstones, and it is also listed as one of the seven treasures in the oriental Buddhist scriptures. It has been regarded as an auspicious thing since ancient times.

Natural red coral is formed by the accumulation of coral polyps. It grows very slowly and cannot be regenerated. However, red coral only grows in the three major straits (Taiwan Strait, Japan Strait, and Baltic Strait), and is restricted by sea areas, so red coral is extremely precious.Jewelry made of red coral is very popular among collectors, and the value-added of fine red coral is very rapid, which is valued by collectors.

The English name of coral is coral, which comes from Latin.The ancient Romans believed that coral had the functions of preventing disasters, giving wisdom, stopping bleeding and driving heat.

In ancient China, red coral was regarded as an auspicious and happy thing, representing noble power, so it was also called "Ruibao", a symbol of happiness and eternity.A famous coral connoisseur said on weekends: "Coral, the elf of the sea."

Indians believe: "Precious coral is the mother of the earth." The Japanese emperor also regards red coral as its national quintessence.Judging from the history of ancient and modern China and foreign countries, red coral has a lofty status.The caps and pilgrimage beads worn by second-rank officials in the Qing Dynasty were made of precious red coral; most of the famous lamas and monks held rosary beads made of red coral.

Now precious red corals are rare and hard to come by, especially coral trees with a height of more than two feet are even rarer.At present, the importance of corals has been gradually recognized by people.

Due to the rarity and non-renewability of coral, it is extremely collectible.Natural red coral jewelry is more popular.

Red coral culture has a long history in the traditional culture of China, India, and Indians. Especially nomadic peoples such as Indian indigenous peoples and Chinese Tibetans love red corals even more. (Emperor)" Blessed sustenance.

According to historical records, the use of red coral by humans can be traced back to ancient Rome.The ancient Romans believed that corals had the functions of preventing disasters, giving people wisdom, hemostasis and expelling heat. Some navigators believed that wearing red corals could prevent lightning and hurricanes, make the wind calm and the journey safe!

Therefore, the Romans called it "red gold", which cast a mysterious color on red coral.Modern Westerners regard coral, pearl and amber as the three major organic gemstones, and it is one of the "March Birthstones" in the West.

There are many kinds of corals, which can be divided into white corals, light pink or dark corals, pink corals, and black corals (ie sea trees) can be seen in Hawaii.Among them, red coral, blue coral and black coral are the most precious.

Taking red coral as an example, there is a saying called "thousand-year coral and ten thousand years red".Red coral is very expensive because of its slow growth, long life, firm quality, bright color, and scarce output.

In the middle of the 16th century, the red coral trade along the Mediterranean Sea was very prosperous, thus creating many masterpieces of red coral art with high value

.The amount of harvested red coral in the world today is between 100 tons and 400 tons per year, and its price is several times or even dozens of times that of gold.

In many auctions, the price of red coral works is also surprisingly high.When coral is made into exquisite ornaments or carved into famous works of art, its worth is doubled.

A good red coral necklace is worth several thousand yuan, and the highest can reach more than tens of thousands of yuan.Especially some fine and precious corals produced in my country's Baodao Strait are unique national treasures owned by our country.

Now Liu Jingjing sees that it is red coral, and this piece of red coral is not only a small piece, but a whole large piece. According to Liu Jingjing's estimation, the range of this piece of red coral is definitely about one kilometer, and, These red corals are all red and red, and even the red ones are a little black.

This kind of red and black red coral is the real top red coral, and the price in the market is beyond imagination! (To be continued, please search, the novel is better and updated faster!
