In the fish family, there are thousands of members, and there are various forms and habits in form, and the appearance is also strange...
<h1 class="pgc-h-arrow-right" data-track="2" > "giants" and "dwarfs"</h1>
Among the large and small fish, whale sharks are undoubtedly heavyweight. It is 20 meters long, weighs several tons, and resembles a small boat on the surface of the sea. As the saying goes, "big fish eat small fish", so whale sharks should be the overlords of the sea, right? No, it is a kind "big brother" among more than 350 sharks, it has no white shark horror, nor tiger shark ferocity. An Austrian underwater explorer is said to have played on the back of a whale shark in the Red Sea. When whale sharks forage in the sea, they can swallow the seawater and plankton together with their mouths, and drain the seawater from the gills through gill filtration. Its main food is plankton.
If whale sharks are giants of fish, then gobys from the Philippines are "dwarfs." It is pitiful, generally only slightly larger than the larvae of mosquitoes, in contrast, the goby appears to be very small, which also refers to adult fish, and the newborn goby is even more minimal.
<h1 class="pgc-h-arrow-right" data-track="5" > tongue sword and lip gun</h1>
The idiom "sword of tongue and tongue" is very appropriate to describe swordfish and water fish.
The jaws of the swordfish resemble a long, flat sword. With this "sword", it can do whatever it wants in the sea, even the big whales are afraid. In 1944, a fishing boat was destroyed by a swordfish in South American waters. What's more, the British warship Lepolit was almost sunk by the sailfish. Of course, swordfish that dare to attack ships will not be good - they often cannot pull out their swords, but can only break the "sword" and stay in the hull.
Shooting fish is shot with water. It swims in the bays and lakes. When it finds flying insects landing on the branches and leaves of aquatic grass or shore grass, they will slowly swim closer, forcefully close the gill cover, use the tongue as a piston, and shoot water out of the mouth like a bullet along the groove of the palate. After this sudden attack, the insect will be shot into the water, and the shooting fish will calmly swim over to eat. It has a high shooting ability, almost within 1 meter, 100 shots.
<h1 class="pgc-h-arrow-right" data-track="9" > log in to climb trees</h1>
People often say that "fish can't do without water", in fact, some fish can't die without water.
The mudskipper has this ability, not only can it bounce around on the beach, but it can also rely on the muscles on the pectoral fin like an elbow, climb to the trees on the shore, "play" for a long time, and then return to the water.
It grows in tropical and subtropical lakes and rivers, and has high climbing skills and can climb to the plane trees on the shore.
Sturgeon, eel and lungfish have similar skills. Lungfish can leave the surface of the water in a dormant state for several months.
Why do these fish have such special features? In addition to ordinary fish, they can also use the swim bladder, skin and intestines as auxiliary respiratory organs to breathe air directly.
<h1 class="pgc-h-arrow-right" data-track="15" > child care magic</h1>
People often treat parents who are too spoiled for their children. He joked, "Take your baby in your mouth." "This is how the Tianzhu seabream is spoiled, just a male fish. Every year, the mouth of the male snapper becomes larger than ever. It holds thousands of fertilized eggs in its mouth and certainly doesn't swallow them. It does not feed until the fish hatches. When it breathes, the eggs in the mouth remain in contact with fresh water, which facilitates the hatching of the fish.
After the eggs turned into small fish, their father took them to the sea to play and eat. However, for a long time, fathers would not let their children go away, and when they encountered danger, they would open their mouths, swallow the children into their mouths, and run away together.
<h1 class="pgc-h-arrow-right" data-track="18" > pick up the light</h1>
The deep sea is almost pitch black, but a kind of trout can pick up a light in the dark and move forward. It turned out that there was a light-emitting device that was transformed from the first fin of its dorsal fin, which could emit red, yellow, and white light, like a small lamp on a bamboo pole.
There are also small fish with circular glowing devices on both sides of the abdomen, which can emit a brilliant luster, and they belong to the lanternfish family.
These glowing fish, using the light they emit, lure the small animals that are phototropic, swallow and eat them; or march forward with their companions; or attract "objects" to mate and reproduce. When the crisis is everywhere, it is also necessary to rely on the flickering light, so that the enemy does not dare to approach, or even flee in panic.
