My Deep-sea Fishery

, The fastest update of the latest chapter of my deep-sea fishery!

Speaking of dugongs, they are also a very poor marine creature. They need to spend a lot of time to eat every day, because it consumes a lot of food, but its speed of action is very slow, and it lacks effective Attack defense means, so it has a lot of natural enemies.

Basically, as long as the marine predators in the ocean are larger than dugongs, they are natural enemies of dugongs.

Due to the high fat content of dugongs, dugongs are precious to humans.

The most precious thing on a dugong is its grease. The ever-bright lamp made of dugong fat has been loved by countless dignitaries at home and abroad. According to legend, the shark oil lamp is made of dugong grease.

In addition, dugong leather is also the best material for making leather. In the romantic Paris, a waistband made of dugong leather was fetched for a sky-high price of 70,000 francs.

In addition, the dugong has a large skeleton, and its bones can be made into valuable sculpture decorations.

So there was a period of time when fishermen all over the world were hunting dugongs frantically. The meek dugongs became the victims of the business interests of mankind. After the frantic hunting of mankind, there are not many dugongs in the world, and they are now on the verge of extinction. edge.

The group of dugongs that Xiang Yang saw in front of him had a total of five heads, two of which were large, one and a half large, and two small, which looked like a family of five.

In fact, this family of five can be regarded as a very large group in the dugong group.

Dugongs like to live together as a family unit. A normal group of dugongs usually has two or three heads, usually two big heads and one small head. Small dugongs will leave their parents and live alone when they are adults. Adult dugongs usually have two or three heads. The offspring will not continue to reproduce when they are underage.

The gestation period of dugongs is generally 11 to 14 months, and it takes 7-8 years for a newly born dugong to reach adulthood. Xiang Yang guessed that the half-year-old of the three small dugongs in front of him should be about five years old, and the two dugongs. Young dugongs are less than two years old, because it usually takes about three years for adult dugongs to give birth to a baby dugong before the second pregnancy.

It is really not easy for dugongs with such low reproduction ability to form a family of five, because young dugongs often become food for other large carnivorous marine creatures. Normally, only one of ten small dugongs can grow up to adulthood.

The slow reproduction speed of dugongs and the harsh living environment have made the number of dugongs declining in recent years. Up to now, few fishermen can hear the "mermaid" singing on the seaside reef in summer.

Xiang Yang didn't want to frighten this group of meek dugongs, and slowly retreated towards the muddy ground behind.

When a little dugong saw Xiang Yang retreating, he seemed to be curious about Xiang Yang. He grabbed his clumsy limbs and wanted to swim towards Xiang Yang.

The action of the little dugong immediately frightened the big dugong, and the female dugong hurriedly pulled the little dugong back, while the male dugong looked at Xiang Yang sternly.

Xiang Yang smiled, and he really responded to the saying that a newborn calf is not afraid of tigers. According to the temperament of an adult dugong, it must be because of the protection of the two dugongs that the dugong is still a tiger. Traveling here, Xiang Yang is not a fierce marine predator, otherwise the little dugong must give away food.

Back to the silt-covered sea area, Xiang Yang did not look for the mussel shell anymore, and went directly upstream. He had been separated from the crew for a while. If he did not go back to the sea, it might cause unnecessary trouble. Panic.

"Captain, you finally came up. I was looking for you under the water just now. Where did you go?" Chen Qingsheng hurriedly shouted when he saw Xiang Yang outcropping.

Xiang Yang climbed onto the deck and took off the helmet on his head. "I saw a few dugongs under the sea just now. I chased them and took a look."

"Dugong is a big guy, Xiaoyang, aren't you hurt?" He Mingde cared.

"It's okay. Dugongs look very big, but they are actually very courageous. They fled immediately when they saw me. I didn't get close to them." Xiang Yang smiled.

"That is, dugongs, as long as they receive the slightest fright, will immediately escape. I have never heard of dugongs attacking humans." He Mingde nodded.

Fang Youqun came over and said with great regret: "Brother Yang, uncle, what exactly is this dugong you are talking about, why have I never heard of it?"

"Dugong has never heard of it. You must have heard of its other name." Chen Qingsheng said thiefly.

"That's not necessarily the case. The books I have read are so few that you can imagine."

Fang Youqun actually went to a junior high school, but he didn’t know how he got it in that junior high school. He eliminated biology and geography. He didn’t have a total of seven lessons in the final exam of the last semester of the third year of junior high school. One hundred points.

"It's a mermaid." Xiang Yang smiled and said: "It's impossible for you to have never heard of this, right?"

Fang Youqun's mouth opened into an o shape, "Mermaid?"

"Right." Chen Qingsheng said with a smile.

Xiang Yang smiled and nodded.

He Mingde also smiled and looked at him.

"The kind of mermaid with a human upper body and a fish lower body?" Fang Youqun asked.

"What do you mean?" Chen Qingsheng asked rhetorically.

Fang Youqun ignored Chen Qingsheng and chased Xiang Yang and asked, "Brother Yang, is the mermaid you saw a male or female?"

At this time Song Chaoshu came over~www.readwn.com~ The mermaid that your boss saw is not the same creature as the mermaid you think. Dugongs and manatees are close relatives, and they are vegetarian mammals, except for their tails. , And the rest is almost identical to the manatee. "

"It turned out to be the manatee." There was a trace of disappointment on Fang Youqun's face.

"Boss Song." Xiang Yang greeted quickly: "Have you heard of the dugong as a marine creature?"

"It's more than I have heard, I have seen it." Song Chaoshu smiled and said: "I don't know if the boss and I saw the same group. If it is the group I saw, they will often appear at night. In this sea area near the coast, there are a total of five heads. It turned out that they came here to forage during the day."

Xiang Yang raised his eyebrows, "What I saw are five heads, two big and three small. Boss Song often sees them?"

"Yes, I prefer the location by the sea. The sea view villas in the city are generally open. Every day, many people go for a walk and make it too noisy, so I bought a piece of land in the country and built it myself. In a house, I unexpectedly discovered that I was a neighbor with the'Mermaid'." Song Chaoshu nodded.
