"Hahaha, it's impossible, the lungfish is not wheat, Jin Kela is useless to it!" After Shen Yibin explained what Jin Ke La was, the guide girl also laughed, "Lungfish generally live by eating fish, molluscs, crustaceans, insect larvae, worms, etc., but they won't eat the Jin Ke La you said." ”

"Huh? Is this fish called a barramundi? Why does it grow in the soil? Shen Yibin asked while scraping the scales and removing the internal organs of these fish, don't all fish grow in water? What's the deal with this kind of thing that grows in the soil?

"That's because barramundi are very, very, very special." The guide girl used three very points in a row to modify, "Most fish use gills to breathe and draw oxygen from the water, but the special thing about lungfish is that it can breathe not only through gills, but also through bladders. The swim bladder of the lungfish has a special opening in the pharynx to communicate with the esophagus, and the swim bladder is subdivided into many smaller air sacs, and it has two such swim bladders, on which a large number of thin-walled blood vessels can absorb oxygen from the air of the swim bladder when blood flows through these blood vessels, so that the lungfish can breathe directly in the air through the mouth. This allows the lungfish to survive for a long time without water, so it can also sustain life in the soil, just like primitive amphibians, and of course, the lungfish is indeed an ancient creature. ”

Wakanda is worthy of being one of the few countries in Africa with developed science and technology, and a small tour guide can understand so much, which makes Shen Yibin and Xia Shixuan listen to it with relish, "But since it can live in the water, why does it run into the soil?" ”

"During the rainy season, when the lake rises, the lungfish will live in the water, and in the dry season, when the lake recedes and the land dries up, the lungfish will use their mouths to dig holes and twist their bodies to expand into a bulb-shaped space, and then secrete mucus to seal the burrow, leaving only a small hole above for breathing, and when the water disappears and the mucus dries up, it is isolated from the outside world. At this point, the lungfish goes into a dormant state, respiratory arrest, metabolism drops to extremely low levels, and it is able to maintain its most basic vital signs by depleting its own muscle tissue. Barramundi survive the dry season, wait for the next rainy season to emerge and still have enough strength to crawl into a nearby pond, a dormant state that is said to last up to four years. The guide girl explained with a drawing.

"Awesome!" Shen Yibin couldn't help but think of the Turtle Daxian at home, this habit of maintaining life through dormancy seems to be quite similar to the Turtle Daxian, if the Turtle Daxian sees the lungfish, he will definitely feel very kind, right?

"In the early years, we used to build our houses out of mud bricks, and sometimes we would accidentally put dormant barramundi into the walls, and in the dry season everything was normal, and in the rainy season, when the rain wet the walls, the barramundi would come out of the walls and swim into the nearby ponds." The guide girl told interesting stories again.

"The owner of this house must not be scared to pee!" I'm lying comfortably at home, eating barbecue and singing, and suddenly several fish come out of the wall, which is a little too scary, isn't it? It's raining outside, and it's getting fish inside, what's going on?

"This property of the lungfish has also aroused the interest of many scientists, think about it, if a critically ill patient can go into hibernation in a critical state and have more time to wait for a well-prepared treatment plan, if astronauts can go into a dormant state during a long period of deep space exploration, it will greatly promote the development of space exploration." "After injecting the rats with substances extracted from the dormant lungs brains, our scientists in Wakanda dropped their body temperature by 5°C, their metabolic rate by 33%, and they became lethargic, and the rats stopped eating the day after they were injected. If it can be combined with the freezing function, it is indeed possible to sleep for several years at a time. ”

I didn't expect Africa to have world-leading research, which is really a little uncomfortable, Shen Yibin was stunned for a while before reacting, and at the same time faintly looked forward to it in his heart, judging from the location of the orange light spot on the pet radar, it seems to be on the other side of the lake, maybe it may really be a lungfish hidden in the soil.

It would be nice if this was the case, not only would Turtle Daxian have a new playmate, but it was estimated that Lu Qiujian could also extract some kind of magical ingredient from it to promote the development of dormancy research, and then cooperate with the enzyme secreted in Turtle Daxian's mouth to expand this function, and the institute would come up with another achievement that shocked the world, what a wonderful thing!

"Okay, I'll help you grill the fish, eat this barramundi with our local seasoning!" Shen Yibin had already dealt with the barramundi, and the guide girl took it from him and prepared to roast it on a portable outdoor stove.

"Give me a try too, and give me some of your spices, when it comes to barbecue, I'm actually very good at it! Well, give me one more. Shen Yibin asked for two fish, one for himself, and one for Ha'er, and the two guys sniffed in front of the spice handed over by the guide girl, and quickly decided on the amount to add.

"Wow, have you ever been to Wakanda before? I think the amount of spice you add is very suitable. Shen Yibin and Ha'er missed a small hand, which surprised the guide girl a little.

"I'm a great barbecue master, uh, this guy is actually better than me!" Shen Yibin just wanted to boast, thinking that Ha'er was still around, he was a little embarrassed, I still learned my barbecue skills from Ha'er.

"Hmm!" Hal raised her head proudly, her paws kept roasting, and she kept sprinkling spices on the barramundi, and after a while, the surface of the barramundi became golden, exuding bursts of charming aroma, which attracted the guide girl and Xia Shixuan to swallow and saliva constantly.

"It seems to be really better than me, so I'll leave these strings to you!" Looking at the fish skewers in his hand again, both the taste and color are far worse than those grilled by Ha'er, and the guide girl directly gave up her own operation and handed it over to Shen Yibin and Ha'er.

"No problem, Hal actually likes to do this!" Hal is usually lazy, but he never spares effort in eating, and these things are exactly what he likes to do.

"Hmm!" The first skewer of grilled fish was ready, and Ha'er sent it to Shen Yibin.

"It's such a big one, I can eat it alone, let's share it together!" This is not a small fish in the Yunshui River, Shen Yibin went to the dinner knife to divide this lungfish into five parts, and divided one for himself, Xia Shixuan, the guide girl, Ha'er and Xiaobai, and handed it to them on a plate.

Then he took out a bottle of monkey wine from his bag, poured it for everyone, and said to the guide girl, "Come and try our own wine, which is made from our fruit, and it is very delicious." ”

"Ah, it smells good." The guide girl has a bold personality, and she doesn't shirk politeness, she directly takes the wine glass, takes a bite of grilled fish with a sip of wine, and enjoys it deliciously.

Xiao Bai swam down Xia Shixuan's legs to his knees, raised his head and swallowed his piece in one gulp, and then looked at Ha'er with blank eyes, now Xiao Bai has grown to three meters long, and this little fish meat is not enough for it to stuff his teeth.

"Hmm!" At this time, the second skewer was also baked, and Ha'er directly handed the skewer to Xiaobai, and Xiaobai swallowed it again, which was equivalent to a little bottom, and then continued to look at Ha'er.

"Hmm~" This time Ha'er didn't agree, I haven't eaten much myself, can't I give it all to you, right? This appearance caused Shen Yibin and them to laugh for a while.

"The taste is really good, but it's a pity that we don't have this kind of fish there, otherwise it would be good to take some back and raise them, and eat a few if you have nothing to do!" The taste of barramundi is extremely tender, but it is a bit like salmon, and Shen Yibin is full of praise for it.

"I'm afraid it won't work, the climate there is too different from ours, and the barramundi won't be able to survive if they go to you." The guide girl was not optimistic about Shen Yibin's plans.

This is also ah, hey, Malfurion will only take care of plants, when can I meet a pet that can take care of animals, Shen Yibin is a little regretful, if you use the kind of pet cage in the pet store that can simulate the natural environment, it's not that you can't raise barramundi, but then the cost is a little too high, I'm afraid I can't afford it.

Eating grilled barramundi, occasionally tasting the fruit of a baobab tree, and monkey wine to drink, the view of the African savannah is mesmerizing, and the day is simply beautiful.

A total of five lungfish were dug out, Xiaobai ate more than two, Ha'er ate more than one, Shen Yibin and the three of them ate one, and their stomachs were full.

"You can rest at night, enjoy the night view, I have set up alarm equipment around, don't worry about any animals breaking in, now I'm going to rest in the tent, tomorrow morning I will call you to get up." After eating, the sun also set on the horizon, and the guide girl packed up her things and went to rest in her tent first.

"The stars in the sky are so bright!" In this land without industrial pollution, the night sky is particularly beautiful, Shen Yibin and Xia Shixuan lay on the moisture-proof mat, looking up at the starry sky, their hearts were full of amazement.

"It's not early, let's go in and rest, we have to go across the lake tomorrow." By the time the moon was in the middle of the sky, Shen Yibin was also a little sleepy.

"Okay, let's go to bed!" Xia Shixuan yawned and followed Shen Yibin into the tent.
