This is for no other reason than to prevent the appearance of hunters. Han Zifeng told Feng Hu the location of this place and said, "This is the place, the mermaid, and the rest is in the live broadcast room. I teleported here, so I definitely didn't take the right route to get in."

Feng Hu entered the live broadcast room quickly. He saw a group of dugongs. Zi Feng happily asked the mermaid to cooperate. She filmed them for about ten minutes and made some spiritual fluid for them. After thinking about it, she asked, "Old Feng, how do you understand functional extinction?"

Feng Hu: "Can you turn all the way back?"

Zi Feng stroked his chin and said, "No, why do I feel that you should come over? There is a group of fish here, they are living well, you just come over to borrow some seeds, they will not refuse."

Zi Feng also discussed it with Dugong. Don't mention it, the guys here really agreed. Zi Feng said seriously: "Yu Yu agreed." What can Feng Hu say? Arrangement.

Zi Feng chose a blank spot in the ocean and asked Xiao Qi to introduce the dugong: The dugong, also known as the mermaid, is a herbivorous marine animal of the family Dugong in the order Sirenia. It is a first-class protected animal in China and one of China's endangered species. The nostril is located on the back of the snout and has a valve. The tail is horizontal with a notch in the center of the rear edge. The paddle-like flippers have no nails. The premaxilla is significantly enlarged and sharply bent downward, and the mandibular symphysis is correspondingly extended and sharply bent downward.

The body is spindle-shaped, about 3 meters long, and weighs 300-500 kilograms. There are sparse short and fine hair all over the body. There is no obvious neck, the head is small, the upper lip is like a horseshoe, the snout is protruding with bristles, and two nearly circular breathing holes are arranged side by side at the front of the head; there is no external auricle, and the ear holes are located behind the eyes. There is no dorsal fin, and the flippers are oval. The tail fin is wide, flat and symmetrical on both sides, with a forked rear edge and no notch. There is a pair of breasts under the flippers. The back is mainly dark gray, and the abdomen is slightly lighter.

Distributed in the East China Sea and the South China Sea, Guangdong, and the southern part of Taiwan, China, the dugongs are also found in the Indian Ocean and the southwestern Pacific Ocean. They mainly live in tropical and tropical shallow waters, mostly in shallow seas with sandy mud bottoms and many green seedlings and seaweeds. They can enter estuaries, but do not live in fresh water. Dugongs like to move in groups, move slowly, have a docile temperament, poor eyesight, and sensitive hearing. They are usually lethargic, sensitive to cold, and are prone to pneumonia and death.

Dugongs feed on succulent aquatic plants such as seaweed and water grass, such as sea leeks, fern algae, salt-loving grass and madder, etc. They move in family groups of 2 to 3 and live at the bottom of seagrass areas with good concealment. They are often mistaken for "mermaids" because they surface to breathe regularly and female dugongs occasionally hold their young in their arms to breastfeed on the surface.

For the second wave, Zi Feng chose the Dabryan sturgeon, which was discovered occasionally. This group is also rare. They are the ones who want to die for you to see. After Zi Feng happily fed the fish, he also re-photographed these guys. Their introductions were also added by Xiao Qi in the later stage.

Acipenser dabryanus, also known as the Yangtze sturgeon, salazi, sturgeon, and sturgeon, is a fish of the genus Acipenser in the family Acipenser in the order Acipenseriformes. It is a first-class protected animal in China.

The body of Acipenser dabryanus is fusiform. The head is wedge-shaped and the back is rough. The front end is conical, the edges on both sides are rounded, there are 4 snouts near the mouth, and there is a water-spouting hole on the head. The nostrils are large, the eyes are small, the gill slits are large, the back and sides of the body are black-gray or gray-brown, and the belly is gray-white. The fins are blue-gray with white edges.

Acipenser dabryanus is an omnivorous fish. Its main food is insect larvae and benthic invertebrates such as Odonata, Ephemeroptera, and Oligochaetes. It also eats the debris of some higher plants, algae, and organic matter in mud and sand. It is mainly distributed in the lower reaches of the Jinsha River and the upper reaches of the Yangtze River. It is occasionally distributed in the lower reaches of the major tributaries of the upper reaches of the Yangtze River and the river section above Jingzhou in the middle reaches of the Yangtze River. It is a freshwater settled sturgeon. The reproductive season is spring. The spawning grounds are mostly in the mainstream of the river. It is most active before spawning. It matures sexually early. Female fish carry a large number of eggs. A female fish weighing 17 kilograms carries nearly 13 eggs. The mature ovary is gray with brown, and the eggs are dark brown.

The third wave she chose was the Baiji dolphin, but these guys actually ran to the sea. Zi Feng still found a few waves of wild ones. Zi Feng followed the prescription and sent the specific coordinates to Feng Hu, saying: "Come and send the Baiji dolphins over here to learn the normal reproduction process."

What can Feng Hu say? Arrangement. As for the introduction of these, it was also filled in by Xiao Qi in the blank space. The Baiji, commonly known as the Chinese pufferfish, the Yangtze River pufferfish, etc., is the only species of the Baiji genus of the Baiji family of the order Cetacea. The Baiji is a critically endangered species and a national first-class protected animal.

The Baiji has a spindle-shaped body, 1.5-2.5 meters long, and can weigh up to 230 kilograms. Its snout is like a bird's beak, extending forward, narrow and long, with the tip of the snout slightly upturned, about 30 centimeters. Its forehead is prominently raised, its nostrils are on the top of its head, and its eyes are very small, located above and behind the corners of its mouth. Its dorsal fin is triangular, its flippers are wide, blunt at the end, and its caudal fin is crescent-shaped. It mainly lives in the middle and lower reaches of the Yangtze River and the waters connected to it, such as Dongting Lake, Poyang Lake, and Qiantang River. It feeds on freshwater fish and often swims to the shallow water near the shore to hunt at dawn and dusk.

But Zi Feng discovered that the Baiji dolphins in the sea have evolved to eat seafood, but those in the mainland still stick to the rules. This is a bit embarrassing. Zi Feng thought that she still had a bunch of friends behind her. Zi Feng calmly threw the question to Feng Hu.

Feng Hu asked speechlessly: "Can we ask the scientists to come over?"

Zi Feng said calmly: "Come over. The problem now is that even if you want to vaccinate, whether the current Baiji dolphins can match your original pair in terms of genetic ratio is still of great research value."

He said to the Baiji dolphin who was listening nearby: "Miss, are you talking about those of our kind who were taken away by humans before they mutated?"

Zi Feng nodded and said, "Yes, yes, they don't even know how to make raw fish. They need to communicate with you and borrow some seeds."

The baiji jumped out of the water, turned around, and then popped its head out and said, "This is easy. If you humans can ensure the safety of the waterway, we can return to live in the river. The problem is that the river is too unsafe."

Zi Feng scratched his head and complained, "Isn't the sea safe? Wait, let me ask you guys about the follow-up."

She said directly to the live broadcast: "Old Feng, now the problem is this, these dolphins in the sea can be returned to the river, but the point is that the river is very unsafe, especially for these baiji dolphins. So, the first thing you need to do is to close the river for a period of time to ensure that they will not be slaughtered when they return. Life is not easy, Yuyu sighed."

Feng Hu said calmly: "Give us some time to make arrangements."
