CATDOLL : CATDOLL: What do swans, barracudas, and shrimps teach us?

1. What do swans, barracudas, and shrimps teach us?

The swan, the barracuda and the shrimp teach us that we should work together and unite as one. If we don't cooperate, nothing will be accomplished.

Many things in life are like this, and cooperation is also a skill. Only when everyone works together can it be accomplished. As long as one person does not work hard, cooperation is impossible. The power of unity can turn everything hopeless into hope.

Story content:

The swan, shrimp and barracuda are three good friends. They discussed and decided to pull a cart to the city together. One day, they prepared the cart and put all the things on it. After the three friends put the rope around them, they started to pull the cart. However, they pulled with all their strength, but the cart did not move at all.

"Hey, what's wrong?" Let's take a look. The swan tied one end of the rope to the car and pulled the other end of the rope. Then, it spread its wings and flew high into the sky. As for the shrimp, it just jumped back, it put the rope around its body and pulled back desperately. As for the pike, it was even more straightforward, it grabbed the other end of the rope and pulled it to the bottom of the pond.

All three of them were pulling desperately, but after working for a long time, the car remained in the same place.

3. What kind of fish is pike? ? ? ?

Pike (Esox reicherti) belongs to the order Salmoniformes, family Pike, genus Pike. Also known as black-spotted pike. Commonly known as: pike, duck fish. English name: Pikes, Amur pike.

The body of the pike is slender, slightly flattened, and the caudal peduncle is short. The head is pointed, and the snout is particularly long and flat, like a duck's bill. The mouth is extremely wide, and the corners of the mouth extend backwards to half the length of the head. The teeth are well developed, and the upper and lower jaws, vomer, ethmoid bones and tongue are all equipped with conical sharp teeth of different sizes. Its teeth are unique. The teeth on the upper jaw can be extended and connected by ligaments. These sharp teeth can hang captured animals, and sometimes uneaten food is hung on the teeth for later use. The scales are small and the lateral line is not obvious. The dorsal fin is located relatively far back, close to the caudal fin, opposite to the anal fin, and the pectoral and pelvic fins are smaller. The back and sides of the body are gray-green or green-brown, with many black spots scattered, and the abdomen is gray-white. The dorsal fin, anal fin, and caudal fin also have many small black spots, and the rest are gray-white.

Pike is ferocious and cruel, and moves extremely fast and agilely. It can swim more than 8 kilometers per hour. Pike is not only extremely ferocious, but also cunning. This is related to its lateral line structure. The lateral line of pike is actually a row of scales with longitudinal grooves. It can not only play the role of vibration sensing point of ordinary lateral line, but also play the role of chemical sensing point. At the same time, pike also has extremely sensitive vision, which enables pike to sense the arrival of prey very quickly. Usually, pike live in slow-flowing rivers, lakes and reservoirs in colder areas. They like to cruise in wide waters and often appear in coastal areas with dense aquatic plants, attacking other fish with their vigorous movements. Juvenile fish are gentle and often live in groups, while adult fish live alone. They have obvious migration patterns. After thawing in spring, they swim to the coastal areas of upstream estuaries or enter small estuaries and marshes to spawn. After spawning, they disperse for fattening and enter deep waters of large rivers to hibernate in winter. Pike feeds on fish and has a large appetite. They continue to feed strongly in winter, especially after reproduction. They usually hunt for food in the early morning or evening. At other times, they stop swimming and rest, and slowly digest the food they have swallowed. Pike is very cunning when hunting. Whenever pike sees a small animal swimming over, they will use their thick tail fin to muddy the water, hide themselves, and stare at the small animal swimming over. When it reaches a certain distance, they will suddenly bite it, and then eat most of the small animal in a few seconds, leaving the remaining part hanging on their teeth for the next time. They stop feeding during the breeding season. Generally, 3-4 winter-old fish reach sexual maturity. The breeding period is from April to early June, with a water temperature of 3-6℃. They spawn in places with aquatic plants at a depth of 0.5-1.0 meters, and the peak of spawning is 1 week. During the breeding season, when waves surge on the quiet water surface, it symbolizes the arrival of female pike. Female pike are much more ferocious than male pike. If it is not the reproductive stage, male fish dare not approach female fish. At this time, female fish swim very fast and irregularly. After swimming fiercely, they enter the place with weeds and stay motionless, waiting for the arrival of male fish. Then male fish swims cautiously towards female fish. At this time, female fish drives away the male fish that they dislike, and the remaining male fish surrounds the female fish. Female pike swims in front of them with extreme excitement, and male pike chases them from behind. At this time, male fish will constantly circle, fight, and kill each other, and then chase the female fish that has swum away. When female pike begins to get tired, it stays in the grass and starts to flip constantly, and the flipping speed is constantly increasing. At this time, male fish approach female fish, roll with them, and sometimes jump up and hit the female fish with their body. After about 15 minutes, male fish begins to ejaculate, and then female fish also ovulates. When female fish is about to finish spawning, male fish flee in a hurry to avoid being bitten by female fish. Although the female fish is quite tired, it still shows its greed and ferocity and starts to eat its own eggs and the male fish that cannot escape. Pike grows fast and has a long lifespan. Some people have found individuals weighing 30-35 kilograms and aged 70. It is said that the longest lifespan can reach more than 200 years.

Pike is distributed in the Heilongjiang River Basin. In addition, another type of white-spotted pike (E. lucius) lives in the Irtysh River Basin in Xinjiang. The difference between them is that the spots on the sides of their bodies are light blue and white.

The natural production of pike in the production area is very large. The meat is tender and white. Except for a slight grassy smell, it is no less delicious than carp, crucian carp or salmon. Pike eggs are poisonous and should not be eaten.
