1, anchovy: this fish body is only 24 to 34 inches, is the world's laziest fish. They are so lazy that they are unwilling to even look for food for themselves, and whenever the big fish eats, they are around the big fish, eating the residue that leaks in the mouth of the big fish. In addition, it does not swim, but relies on the natural mouth suction cup, sucks the bodies of other big fish, and follows the big fish to any place where it likes to go. It is very familiar with the personality and frequent places of all kinds of big fish, so if it wants to go there, it will catch the "passing boat" it needs for free.
2, toadfish: the head has a thin and long rod-like organ, the top can emit light blue light, it generally lives on the deep seabed, in the dark world of the seabed like a small lamp shining. The "toadfish" weigh dozens of pounds each, and they are particularly not fond of sports, even if they catch food, they do not move the place, but open their mouths and wait for food to be delivered to the door by themselves. The way it catches food is to use some small animals to curiously surround the bright light, and the result is that before it can get close to the "light", it is swallowed by the open mouth.
3. Half-sided fish: In the Muluo River of Guangxi Huaping Nature Reserve, there is a kind of half-scaled and half-scaled half-sided fish. Once the male and female of this fish are combined, the husband and wife sing along, love and love, and never separate.
4, gill next to the turtle fish: There is a kind of yellowtail in Langui Creek, Hunan, with a large and thin head, weighing only one or two, but five inches long. The strange thing is that each female yellowtail has a small hole next to the gills, and inside the hole is a small turtle with a large shirt button and translucent, commonly known as the "fish turtle", which can be taken out and put into the water to swim freely.
5, anchovy: its head is up, tail is down, standing up on its stomach, swimming like a human walking. This fish is 2 to 3 inches long, covered with hard armor, can not be eaten, but because of its thin and transparent form, and with fragrance, after drying can be used as a bookmark, therefore, people call it "bookmark fish".
6, cod: The world's most cold fish is antarctic cod. In ice water at minus 1.9°C, it freezes without freezing. That's because it contains an ingredient called sugar dirty in its blood, and its efficacy is similar to that of antifreeze in a car.
7, lungfish: produced in Africa, this fish can continue to live in the case of water loss for more than 4 years, when a drought occurs, the lungfish will dig a pit at the bottom of the river, and then make a mud sac with mud and clay, and open a stomata on it to seal itself inside. Before long, the mud sac became dry and hard, but the lungfish was protected. When it rains, the mud sac dissolves and the lungfish swim away from the water.
8, fire-breathing fish: There is a kind of fire-breathing fish in the Indian Ocean, its body is not large, only about 20 centimeters. But it has a subtle protective "weapon". Fire-breathing fish can usually take in phosphorus-containing organic matter from food and constantly store it in the body, and once they encounter ships or predators, tens of thousands of fire-breathing fish will spit out this organic matter. Phosphorus spontaneously combusts in oxygen, and can spew out a flame more than 3 meters long to shoot at the enemy, causing the enemy to turn around and flee in fear.
9, human tooth fish: also known as Paku piranha, is a close relative of sawfish, is a kind of fruit fish living in fresh water, mainly eat nuts falling in the water, with similar human teeth for cracking nuts and fruits and named. Weight up to 18 kg. The toothfish usually live in the Amazon basin and were later introduced to Papua New Guinea. Because the rivers here lack food, they also live off meat in order to survive, especially in the water to sneak into the crotch of fishermen, two men were reported to have died after being bitten by this strange fish in 2011. Be especially careful if the male is active in its waters. Because it especially loves "trick-or-treating"!
10. Piggy Octopus: One of its distinguishing features is that there is a luminous organ under the eyes, which can produce orange light. Researchers have photographed rare piglet octopuses in the deep seas, which have a very similar appearance to human pigs: rounded bodies, curly "mane", and smiling faces. Since it usually lives in deep waters 100 meters under the sea, people rarely know its behavioral characteristics, but judging from its body size, it is a slow-moving octopus. The piglet octopus is only 4 inches long and has unusual pigment deposits on its body, so named after its rounded body and curly antennae. This piglet octopus is the size of a larger orange.
