What does it mean when the saying goes that if you give a fish, you can’t give one?

The homophony of fish is "surplus", which means there will be more than one year after year. Sending fish means: sending wealth, good luck, and having more than one year after year, which means a good omen.

When fish comes, you will be praised. It means beautiful (mermaid);

Send two fish, and two means "a pair";

Three, fish (surplus), I mean two One of the fish should be smaller, that is your substitute.

The girl’s expression was too tactful, and it didn’t seem like something a grown man would do. Fish is a creature that longs for freedom... but it is also a free creature... Just like you, it longs for happiness... but in possession of happiness...

How do fish trap small fish?

The hunting methods of marine carnivorous animals are nothing more than forceful feeding and outsmarting. Hammerhead sharks, killer whales, etc. are ferocious and cruel animals in the ocean. They can bite sea fish into three pieces in one bite and hunt food with their ferocity and strength. There are also many marine carnivorous animals, which are small and slow-moving, and rely on disguise to trap food.

For example, the mackerel and bighead carp can emit light to attract small fish. Another example is the piebald frogfish we are going to introduce in this article. It is also a marine fish that relies on disguise to outsmart its food. The piebald worm looks like a piece of coral, or like a molten fish attached to a rock on the sea floor, specially transformed into an ingenious trap, located above the snout, like a fishing rod stuck on the head.

This fishing rod is slender and bendable, with a real bait at the tip - a fat claw. Sometimes this piece of chelicerae looks like a living fish swimming in the water, sometimes like a wriggling earthworm, and sometimes like a jumping shrimp. If this piece of chelicerae is bitten off by a fish with sharp teeth, another piece will grow back later.

Someone wearing a diving suit observed the entire process of a piebald gall feeding on a butterfly fish underwater. A "little shrimp" on a piebald "fishing rod" attracted a beautiful butterfly fish. Before the butterfly fish could swim to the "little shrimp", the butterfly fish suddenly disappeared. People only saw that the water around the flower spot was slightly turbid, but there was no other trace, as if nothing had happened.

This "shrimp" on the "fishing rod" is still swinging back and forth there. It turned out that as soon as the butterfly fish came into the field of vision of Huaban Zang, the "fishing rod" on its head could very sensitively feel the water waves generated when the butterfly fish swam closer, so Huaban Zou moved with lightning speed. Open your mouth and expand it to 12 times its original size. At this time, your mouth is like a powerful water pump, swallowing a large amount of water together with the butterfly fish. The total time spent is no more than a thousand minutes. six seconds.

The moment it opens its mouth to absorb water, the butterflyfish shrinks its gill slits very tightly to prevent water from leaking. It waits until the butterfly fish has eaten before expelling the inhaled water out of the body through its gills. The Pied Piper usually moves forward by jetting water. It first sucks water into its mouth, and then ejects it forcefully backward through the long tubular gill slits, using the recoil effect to swim forward quickly.

At this time, the pelvic fins on both sides of the piebald fin act as water wings, and the tail fin acts as a rudder, zigzagging among the coral reefs. After finding a suitable place, it quickly lands and disguises itself again as a piece of coral or a sponge attached to a rock, waiting motionless for its prey to take the bait. There are several species of frogfish, most of which live in shallow waters in temperate and tropical waters.

Among the few species of frogfish that live in the deep sea, there are luminous bacteria living on the end flap of the "fishing rod", which emits green fluorescence deep in the seabed, making it easier to lure prey to the bait. The fish also often changes its body color according to the living environment, creating a mimicry. Even if the enemy is not easy to detect, it can also make small fish and shrimp lose their vigilance and make them easy to take the bait.

The former is characterized by three or four forks at the upper end of the "fishing rod", while the latter is characterized by a spherical upper end of the "fishing rod" and round spots at the base of the dorsal fin rays. Collapse
