Chapter 1829: Flying Fish
Hearing what Dad said every day, he said, ‘Okay then! My mother and I are waiting for you on this spaceship. ’
So, Zhao Luyao and Feifei arrived on this small island. The two of them looked around on this small island, but they didn't see any amethyst gems either.
On this small island, there is a bare reef, and there is no amethyst gem they are looking for.
After all, amethyst gemstones 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 will be amethyst gems. Let’s go and see somewhere else! Said Feifei.
After hearing what Feifei said, Zhao Zhongyao thought for a while and said, ‘what you said is that this place is unlikely to have amethyst gems. Let’s go and see it elsewhere! ’
Just when Zhao Zhongyao said this, some'big birds' flew up from the nearby sea. These big birds flew in front of Zhao Zhongyao and Feifei, and flew over their heads.
When Feifei saw these "big birds," he looked at Zhao Zhongyao in surprise and asked, "Dad, what is this--is it some big birds!" ’
Zhao Zhongyao was also very surprised, but he felt that these things were not very big, they were some birds about the size of a falcon.
‘I don’t know either, but let’s not be afraid, they are not very big! Said Zhao Zhongyao.
Zhao Zhongyao said and observed carefully. By looking at it, he felt that these things were not big birds, but some big fishes.
‘What Dad said is that these birds are not very big, we don’t have to worry about them. Feifei said, looking at the big bird in the sky.
‘Feifei, these are not birds, but fish. Said Zhao Zhongyao.
‘What, it’s not a bird, it’s a fish! Feifei looked surprised.
‘Look, is their body a fish? Said Zhao Zhongyao.
After hearing what Zhao Zhongyao said, Feifei took a closer look at the birds in the sky, and felt that they were really fishes, not real birds.
‘Dad, how can these fish fly! Feifei is still very puzzled.
Zhao Zhongyao said, ‘have you never heard of flying fish? ’
When Zhao Zhongyao said this, Feifei also thought about the fact that there is a kind of fish in the sea that can fly.
‘Dad, I know, there is indeed a kind of fish that can fly in the sea, we call it flying fish. Are these fish the same as those fish! However, I feel that this kind of flying fish seems to be very big. Said Feifei.
‘Yes, the flying fish here are much larger than the flying fish on earth. Said Zhao Zhongyao.
‘Dad, do you know the flying fish on earth well? Then can you tell me something about flying fish. Feifei asked.
‘Ok, then I will tell you something about flying fish on earth! Said Zhao Zhongyao.
Next, Zhao Zhongyao told Feifei some knowledge about flying fish.
Flying fish have a peculiar appearance, with particularly developed pectoral fins, like the wings of a bird. The long pectoral fin extends to the tail, and the whole body is like a "long shuttle" of weaving cloth. With its beautiful streamlined body shape, flying fish can move at high speeds in the sea at a speed of 10 meters per second.
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 back color of flying fish is similar to that of sea water, and it often moves on the surface of sea water. It often flies in groups on the sea, resembling a carp, with a bird-wing fish body, a white head and a red mouth, and a cyan texture on the back. It often flies at night.
The flying fish accelerates underwater, and when swimming towards the surface, the fins cling to the streamlined body. As soon as it breaks through the water, the large fins are opened, and the tail part still in the water quickly to gain extra thrust.
When the power is enough, the tail is completely out of water, so it vacates and glides a few feet above the water at a speed of 16 kilometers per hour. Flying fish can glide continuously, 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 at a time, and the continuous glide (up to 43 seconds) distance can be as far as 400 meters.
In fact, the "flying" of flying fish is just a kind of gliding. Scientists used cameras to reveal the secret of flying fish "flying". Flying fish actually uses its tail to slam the sea to take off, instead of flying by vibrating pectoral fins as people imagine.
Before the flying fish comes out of the water, adjust the angle to swim quickly under the sea surface. When approaching the sea surface, close the pectoral and pelvic fins to the sides of the body, and then use the powerful tail fin to swing sharply from side to side to draw a zigzag It produces a powerful impulse, prompting the fish to burst out of the water like an arrow, with a take-off speed of up to 18 meters per second.
After exiting the water, the flying fish immediately opened their long and wide pectoral fins, and glided at a speed of about 15 meters in the sea wind. When the wind is right, the flying fish can fly 200 to 400 meters in the air 4 to 5 meters above the water.
When the flying fish returns to the water, if it needs to take off again, it will beat the waves with its tail before the whole body is in the water to increase the gliding force, make it jump out of the water again, and continue to glide briefly.
Obviously, the flying fish's "wings" did not actually flap, but only relied on the thrust of the tail to make a short "fly" in the air. Someone has done 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 of a bird and cannot flap its "wings", the flying fish with its tail fin cut off can no longer take off.
After hearing what Zhao Zhongyao said, Feifei also had some understanding of this miraculous creature in the sea.
At this time, he looked at Zhao Zhongyao again and said, ‘Dad, these birds are just some flying fish. I don’t know what they are doing flying around here! ’
‘Maybe it’s preying on flying insects in the sky! Flying fish not only eat some plankton in the sea, but also catch some small flying insects in the air. Said Zhao Zhongyao.
‘Oh, they are eating! Said Feifei.
‘Yes, we don’t care about them, let’s go back to the spaceship! Said Zhao Zhongyao.
‘Okay, let’s go back to the spaceship first,’ said Feifei.
In this way, Zhao Zhongyao and Feifei returned to the spaceship together.
It's just that after seeing Zhao Zhongyao and Feifei leave, these flying fish also came to the spaceship together. It seems that they are very interested in Zhao Zhongyao and Feifei, and want to follow them all the time.
