Daily Forest Ranger: Start Saving Giant Pandas

Chapter 33 A snow-white flying squirrel suddenly appeared in the cave
Looking at the barrage, Lin Xuan walked over curiously.

Sure enough, here, a pond was found.

When Lin Xuan's light shone on the water surface of the pond, he saw the shadow of something flashing past.

Seeing this situation, Lin Xuan was a little surprised. He stopped, and regardless of the coldness of the ground, he crawled directly on the edge of the pond and looked into the pond carefully.

The bottom of the pond is rather dim, so it is not very clear, but what is certain is that there are indeed things moving slowly in this pond.

Seeing this situation, Lin Xuan immediately confirmed that there was indeed some kind of creature in the pool. As for what kind of creature it was, he could only know it when he saw it clearly.

Thinking of this, Lin Xuan got up from the ground, opened the system store, and exchanged it for an underwater micro-drone that was only the size of a thumbnail!
When this thing appeared, Lin Xuan dropped it into the water. In order not to disturb the unknown underwater creatures, he deliberately lowered the drone slowly.

The water in the pool is very clear, so the field of vision for shooting is also very good.

When it dived to a certain depth, a group of thin and small things appeared in the camera.

Their body length is about 10 centimeters, and their bodies are translucent, just like Libo blind loach.

Under the light, the body is as transparent as jade, and the internal organs and blood vessels are clearly visible.

(Fuck, there are still fish in this pond!)

(Have they always lived here without seeing the sun all year round?)
(Anchor, anchor, what kind of fish is this?)
"If I'm not mistaken, this should be a cave fish."

(Cave fish? Is it called this because it has been living in caves? This is too random.)
(Haha, I think this name is very suitable for this kind of fish.)
"Cavefish have small eyes and no visual function. Sensitive tactile organs are all over the body, head and tail, so they can feel things they can't see."

It shows obvious degeneration trend, which is mainly manifested in the distribution of body scales and the relative size of lateral line scales. For example, the body scales of giant bearded golden wire gills are obviously smaller than the lateral line scales.

The species with more developed body scales, or the side scales are larger and cover the entire body, arranged in an imbricate shape, and some species retain sheaths at the base of the dorsal fin, such as the small eye golden line gills, etc., or the side line scales are equal to or slightly larger than the upper and lower side line scales.For species with smaller body scales, the lateral line scales are significantly larger than the upper and lower lateral line scales.

For species with relatively degenerated body scales, the scales are not only thinner and thinner, but also hidden in a neat mosaic arrangement under the skin, covering the entire body, and the base of the dorsal fin is exposed without a sheath, such as the humpback golden thread gills.

The most extreme example of scale degeneration is transparent gold thread palladium, etc., whose whole body is bare without scales, only a very thin lateral line remains under the skin, and the lateral line hole remains on it.

It can be seen from this that the degeneration rate of the lateral line scales is obviously slower than that of other body scales. This phenomenon of allometric degeneration of body scales also exists in other carps, and it may be a common phenomenon in the scale degradation process of carps. evolution trend.

The body surface scales of Libo blind squid have basically degenerated. Under the microscope, it can be found that only a very small amount of scales are hidden under the skin of the head and back, which can only be seen after dissection or scraping. Moreover, the scales of Libo blind squid have basically degenerated into Components of the skin.

The species of burrowing animals living in completely dark underground currents have no pigment (except hemoglobin) and are translucent, such as the Libo blind loach, which is pure white and transparent in the water body under investigation at night, and the body of the living body under the light Transparent as jade, internal organs and blood vessels are clearly visible.

According to the literature, Lin Xuan popularized science to netizens.

(It turned out to be like this, but looking at the appearance of these cave fish, they are also very cute.)
(Upstairs, whatever you see, just say it’s cute.)
(However, they have been living in caves and have not seen the sun for many years. Wouldn’t they be very lonely?)
"Actually, each species has its own way of survival."

"For example, in the deep sea, there are also transparent fish, because they have not seen the sun for many years."

"I didn't expect that when I entered this cave, I could actually see such a creature in it."

"Perhaps there are other things that can be seen further down the cave."

For this, Lin Xuan was also full of expectations.

Just when Lin Xuan was about to move on, suddenly, Du Luo, Du Luo's voice came from his ear.

(What is that sound? It sounds a little scary.)
(In this cave, such a voice suddenly came. Although I was broadcasting live, I was shocked by this sudden attack.)
Lin Xuan was also a little confused about the appearance of this voice.

After thinking about it, Lin Xuan decided to go and have a look.

He followed the direction of the sound and searched for the past.

Under the light of the flashlight, a creature that looked like a squirrel soon appeared in everyone's field of vision.

(is this a squirrel?)

(No, this squirrel-like creature seems to have wings.)
(The big black eyes and the hair all over the body are basically snow white. It looks so cute!)
(Indeed, I also feel that this squirrel-like creature is much cuter than the group of cavefish just now.)
When everyone saw the appearance of this squirrel-like creature, they all called it cute.

At this time, Momei Ruhua also appeared.

In the live broadcast room, she was popularizing science: (This should be the compound-toothed flying squirrel. The compound-toothed flying squirrel is also called orange-footed flying squirrel, yellow-footed flying squirrel, cold bird, cold bug, and cold tara. It is a rodent animals.)
(Although the name is Han Haoniao, it is not a bird because it can fly.)
(??? An animal like a squirrel can actually fly?)

"Mo Meiruhua is right, this is indeed a compound-toothed flying squirrel."

"It's just that they don't really fly in the sky, they just glide."

"In addition, flying squirrels are not squirrels, they are small animals of the suborder Sciurus."

Lin Xuan explained.

(Oh, I said, seeing this squirrel-like animal, why does it look familiar? It turned out to be a compound-toothed flying squirrel. I have seen this kind of video on Xiaopozhan. The compound-toothed flying squirrel in it is raised of.)
(As long as you stretch out your hand, it will fly to your hand from a high place.)
(But this kind of creature is also more prone to autism. If you don't catch it when it flies over, it is very likely to cause autism and then commit suicide.)
(???)

(This is too cute, like the kind where your girlfriend gets angry and you can't coax her well.)
