Chapter 1829: Flying Fish

, super military scientist! Chapter 1829 Flying Fish

After hearing what my father said every day, I said, 'Okay then! My mother and I are waiting for you on this spaceship. '

So, Zhao Luyao and Feifei came to this small island. The two of them searched the small island, but they didn't see any amethyst gemstones.

On this small island, there is a bare reef, and there is no amethyst gem they are looking for.

After all, amethyst gems are produced in some very special places. Especially in these places, there must be life. If there is no life, it is unlikely that there will be amethyst gems.

‘Dad, there is no life here, it is unlikely that there are amethyst gems, let’s go to other places to have a look! ’ Said Feifei.

After hearing Feifei's words, Zhao Zhongyao thought for a while and said,'What you said is that it is unlikely that there are amethyst gems in this place. Let's go to other places to have a look! '

Just when Zhao Zhongyao said this, some'big birds' suddenly flew from the nearby sea. These big birds flew in front of Zhao Zhongyao and Feifei, flying around above their heads.

As soon as Feifei saw these'big birds,' he looked at Zhao Zhongyao in surprise and asked,'Dad, this--what are these things, are they some big birds! '

Zhao Zhongyao was also very surprised, but he felt that these things were not very big, they were just birds about the size of falcons.

'I don't know either, but we don't have to be afraid, aren't they big! Zhao Zhongyao said so.

Zhao Zhongyao said while observing carefully. When he looked at it, he felt that these things were not big birds, but some big fish.

'What Dad said was, these birds aren't very big and we don't have to worry about them. ’ Feifei looked at the big bird in the sky and said.

‘Feifei, these are not birds, but some fish. ' Zhao Zhongyao said.

‘What, it’s not a bird, it’s a fish! ’ Feifei looked surprised.

'Look, are their bodies fishes? Zhao Zhongyao said so.

After listening to Zhao Zhongyao's words, Feifei took a closer look at the birds in the sky, and felt that they were really some fish, not real birds.

'Dad, how can these fish fly! ’ Feifei was still very puzzled.

Zhao Zhongyao said, 'Haven't you heard of Feiyu? '

When Zhao Zhongyao said this, Feifei also thought of the fact that there is a fish in the sea that can fly.

‘Dad, I see, there is indeed a fish that can fly in the sea, we call it the flying fish. Are these fish the same as those fish! However, I feel that this flying fish seems to be very large. ’ Said Feifei.

‘That’s right, the flying fish here are much larger than those on Earth. Zhao Zhongyao said so.

‘Dad, do you know the flying fish on Earth very well? So can you tell me something about flying fish. ’ Feifei asked.

‘Okay, then let me tell you something about flying fish on Earth! Zhao Zhongyao said so.

Next, Zhao Zhongyao told Feifei some knowledge about Feiyu.

Flying fish have a strange appearance, with particularly well-developed pectoral fins, like the wings of birds. The long pectoral fins extend all the way to the tail, and the whole body is like a "long shuttle" weaving. With its streamlined and graceful body, flying fish can move at a high speed of 10 meters per second in the sea.

It can jump more than ten meters above the water, stay in the air for more than 40 seconds, and fly more than 400 meters. The color of the back of the flying fish is close to that of sea water, and it often moves on the surface of sea water. It often flies in groups on the sea. It looks like carp, with bird wings and fish body, white head and red mouth, and blue texture on the back. It often flies at night.

Flying fish accelerate underwater, with their fins pressed against their streamlined bodies as they swim toward the surface. As soon as it breaks through the water, spread the large fins and quickly flap the tail while it is still in the water, so as to obtain extra thrust.

When the power is sufficient, the tail is completely out of the water, so it flies into the air and glides a few feet above the water surface at a speed of 16 kilometers per hour. Flying fish can do continuous gliding, and each time they fall back into the water, the tail pushes the body up again. The stronger flying fish can glide up to 180 meters in one glide, and the distance of continuous glides (up to 43 seconds) can be as far as 400 meters.

In fact, the "flying" of flying fish is just a kind of gliding. Scientists have used a camera to reveal the secret of the flying fish's "flying". The flying fish actually uses its tail to slam the water to take off, instead of vibrating its pectoral fins as people imagined.

Before coming out of the water, the flying fish first adjusts the angle and swims quickly under the sea surface. When it is about to approach the sea surface, it sticks its pectoral and pelvic fins to the sides of its body, and then uses its powerful tail fin to swing sharply left and right to draw a zigzag water mark, making it It produces a powerful momentum, prompting the fish body to burst out of the water like an arrow, with a take-off speed of up to 18 m/s.

After coming out of the water, the flying fish immediately opens its long and wide pectoral fins and glides against the sea wind at a speed of about 15 meters per second. When the wind is right, the flying fish can fly 200 to 400 meters in the air 45 meters above the water.

When the flying fish returns to the water, if it needs to take off again, it will use its tail to beat the waves before its whole body enters the water to increase its gliding power, so that it can jump out of the water again and continue its short gliding flight.

Obviously, the "wings" of the flying fish do not actually flap, but only rely on the propulsion of the tail to make a short "flight" in the air. Someone once did an experiment to cut off the tail fin of a flying fish and put it back into the sea. Because it does not have the developed pectoral muscles like birds and cannot flap its "wings", it was cut off

The flying fish with tail fin can no longer take off into the air.

After listening to Zhao Zhongyao's words, Feifei also had some understanding of this magical creature in the sea.

At this time, he looked at Zhao Zhongyao again and said, Dad, so these flying birds are flying fish. I don't know what they are doing flying around here! '

‘Maybe they are preying on flying insects in the air! Flying fish not only eat some plankton in the sea, but also prey on some small flying insects in the air. Zhao Zhongyao said so.

'Oh, so they are eating! ’ Feifei said.

'That's right, we don't care about them, let's go back to the spaceship! Zhao Zhongyao said so.

'Okay, let's go back to the spaceship first,' Feifei said as well.

In this way, Zhao Zhongyao and Feifei returned to the spaceship together.

It's just that these flying fish came near the spaceship together after seeing Zhao Zhongyao and Feifei leave. It seems that they are very interested in Zhao Zhongyao and Feifei, and want to follow them all the time.
