The temperature in Guangzhou is now thirty degrees, so hot, I feel that in a few days I can swim to cool off.
For this reason, the fawn has not eaten supper for a week, just so that I can wear a beautiful swimsuit and expose the flesh of the white flowers that I have worked so hard to cover for half a year! For the sake of safety, I also learned what things can't be messed with in the water.
01 The red-bellied sawfish (Pygocentrus nattereri), also known as the red-bellied goby, has a very popular name - piranha.
But you don't have to worry, the range of wild individuals is not in China's territory, the habitat is the Amazon River Basin of South America, like to live in tropical freshwater rivers, but now the environmental pollution is so serious, global warming, maybe a careless species invasion.
Uncle Fox said that this thing can be delicious braised, so it is estimated that it can only end up with crayfish when it comes.
The body length of the red-bellied sawfish is 20-30 cm. The back is dark green and the abdomen is large patches of bright red. It has sharp teeth, arranged in a jagged arrangement, as a scissor bite, and the jaw is also strong and powerful, and can bite off a steel fishing hook about 1 mm in diameter. At noon, they gather in the shade to rest, adult individuals are generally active in the morning and dusk, and juveniles are active all day.
Once they have bitten their prey, they cling to it, tearing the flesh off with the writhing of their bodies. Often in groups, the waters become smaller during the dry season, and the species gathers in large groups to attack animals that pass through the waters.
The piranha in the general anime looks like this:
Comics are indeed a magical thing, no matter what, as long as they are drawn, they look good, and the wives are simply god-like beings.
Piranhas have pointed teeth that are suitable for biting food, so they are meat-eating, small ferocious carnivorous fish, generally feeding on small fish, shrimp, crabs and insects, and sometimes attacking large injured animals.
One of his close relatives, though they don't eat meat and like to eat fruit, are a more potential threat to humans, and this is aimed at men.
02 Pacu fish, commonly known as egg-cut fish.
Generally speaking, his range of activities is not in China's territory, usually living in the Amazon basin of South America, larger than piranhas, up to 90 centimeters in the body, the heaviest weight up to 25 kilograms, but people are vegetarian.
However, due to artificial release, sawfish are now also seen in other river basins.
His teeth resemble human teeth, and their teeth are more peaceful and powerful than human teeth, more suitable for crushing food. It mainly depends on the consumption of dried fruits, leaves, aquatic vegetation and snails.
Everyone may be curious, he is not a vegetarian, how can he be interested in eggs?
If the male compatriots are swimming naked (the fawn recommends that the little brothers have to swim in the wild, it is best to wear small pants), you can see for yourself, the egg floating in the water is not like a fruit falling in the water?!
In 2011, two fishermen in Papua New Guinea were bitten in a lake, and the local government has issued a warning that any form of naked swimming in the basin is prohibited.
In addition to the similarity in appearance, there are other reasons, such as the size of the entrance (please compare your own eggs with the size of the sawfish in the picture above after opening its mouth). In addition to size there is another reason, the smell!
In the ninth episode of the documentary "Primitive Survival", there is a fragment of the text that appears to fish for sawfish with fruit, and he said this:
Saw belly carp like to eat such a heavy taste, so the way to prevent being bitten is very simple, keep yourself clean and hygienic, they will dislike you too fragrant, it is not delicious at first glance, and then do not swim naked in their range of activities.
In addition to the fish that bite people, there are also fish that can discharge electricity, and I sincerely sighed that the water is really unsafe.
03 Electrophorus electricus is commonly known as the "high-voltage line" in the water, but people are not eels.
Eels are the suborder Eels of the order Eels, and the electric eel is a suborder of the new-finned fish order Electric eels.
Some time ago, Douyin had a very hot sentence: I thought I had entered my brother's fish pond. Didn't expect my brother Aquaman. Someone picked up the sentence later, but I am different, I am an electric eel, electrocuting the fish in your sea!
Electric eel is the most powerful freshwater fish, the output voltage can reach 300 ~ 800 volts, other fish in the electrostatic water can, but do you want to consider it - electric eel is a freshwater fish!
Mainly living in the Guiana region of the Amazon basin of South America, it is very large in shallow ponds or on the shores of more turbid water bodies, and is a famous edible fish of origin, and can also be used as a display fish or ornamental fish in aquariums.
There was news before that the electric eels at the Sendai Aquarium had knotted themselves into knots that could not be untied.
The original text goes like this: This will affect the daily life of the eel, if you can't solve it yourself, you will need manual help, but - you have to corona him first, and then untie him, otherwise he will give you corona first.
The principle of electric eel discharge is as follows:
The muscles on both sides of the electric eel are composed of regularly arranged 6000 to 10000 muscle flakes, no muscle flakes are like a small battery, which can only produce a voltage of 150 millivolts, but nearly 10,000 small batteries are connected in series, and the voltage during discharge will be as high as 600-800V, but this voltage can only be maintained for a very short time.
Although the piranhas mentioned above are very ferocious, they can't fight electric eels, and electric eels can directly electrocute a group, just like I have electric fish in the pond, and immediately turn over.
However, the electricity of electric eels is not only short in duration, but also has a disadvantage - it cannot be discharged continuously for a period of time. So the way to catch the electric eel is very simple, let him discharge, empty can be fished, it is said to be quite delicious!
I suddenly remembered, I can't swim! And I can't come to Amazon!
Forget it, let's eat tonight's supper! Can't swim anyway, can't treat yourself badly! By the way, how did you learn to swim? Can you share your learning experience?
Love you guys!
