Among the fish that feed on insects, some species can not only eat aquatic insects, but also do not easily let go of terrestrial insects that stay on the shore and skim the water, this is the shooting fish living in the Amazon River, and its superb skills make people have to be impressed by it.
Most of the shooting fish live in the coastal waters and rivers near the Spratly Islands and Polynesia, its body is flattened, the mouth is relatively large, can be retracted, the lower jaw is prominent, in the front half of the head, their body color is very bright, the body is olive, there are several thick limestone blue stripes across the back, the tail is light yellow, is also the best ornamental fish. Generally, the body length of the water jet fish is only about 20 cm, it has a pair of blister eyes, the whites of the eyes have a continuous rotation of vertical lines, when swimming on the surface of the water, you can also see close objects in the air, shooting fish like to eat animal food, especially like to prey on living outside the water, live small insects, in the natural environment, branches near the water surface and grass leaves on flies, mosquitoes, spiders, moths and other small insects, are its prey objects.
The hunting activity of the shooting water fish is very similar to an experienced hunter, when it finds prey, such as insects flying on the shore water grass, it will immediately become excited, first stretch the dorsal fin, carefully approach the water grass, and silently swim around the water grass, choose a favorable terrain, after choosing the middle position, stop the activity, ready to enter the battle state, it gently strokes the pectoral fin, quietly sticks its mouth out of the water, suddenly, a stream of water like a water gun shoots towards the little insect, the little insect turns over and falls into the water, At this time, the shooting fish immediately rushed to the prey, bit it, and swallowed it into its belly. And its hit rate for shooting insects is quite high, within a distance of more than one meter, there are no bullets, and it can almost reach 100 shots.
So the question is, what exactly is the mystery of the spray water gun that shoots water fish
On the surface, there is no difference between the shooting fish and other fish, but its mouth structure is very special, in its upper jaw there are two small small grooves, when the tongue is tightly attached to the palate, this deep groove becomes the barrel, when shooting water, its gill cover is pressed sharply, the water contained in the mouth is ejected from the mouth through the small groove, the water shot by the shooting fish can also change, sometimes "burst" sometimes "point shot". These ingenious actions are completed by the change of the tip of the tongue, the tip of its tongue is like a trapdoor, when the tip of the tongue is down, the trapdoor opens, a stream of water shoots out, this is the so-called "burst", if the tip of the tongue lifts and falls, there are water droplets shot out in a beam, this is "point shooting". This different method of shooting water, like the military using automatic rifles, is really a god, in general, the "water gun" shot by the water fish is radioactive, when it is close to the target, it can emit several small water bombs, expand the shooting surface, thus ensuring the hit rate, really worthy of being a "sharpshooter" in a hundred shots.
The stunt of shooting water fish has attracted the attention of scientists, after the research of scientists, the accuracy of shooting water fish shooting is within one meter, almost can reach the extent of bullets, and different types of water fish, the shooting distance is inconsistent, the farthest can reach about 4 meters, the reliable range of general water fish is 1-2 meters, and scientists have also found that not only insects, water fish also have a certain phototaxis, sometimes even the cigarettes lit by people on the shore, as long as they are within range, sometimes it also becomes its shooting target.
Shooting fish is a fish with a beautiful body size and color, easy to raise, and has the skill of shooting water to hunt, which is very popular with viewers.
