What kind of fish can shoot "water guns"?

In India and Southeast Asia, there is a kind of archer fish known as "living water gun" and "sniper", also called water bomb fish. It is fifteen or six centimeters long, silver-white, with a flat body, and its appearance is not unusual. Its particular function is to draw water to catch prey. When it swims, its eyes are always scanning the water above to see if there is anything delicious. When it finds flies, mosquitoes, dragonflies and other insects flying above the water, or resting on blades of grass or stones at the water's edge, it gently swims up at a place about 1 meter from the insects, adopt its posture and raise its head. It comes out of the water, holds its sharp beak, straightens its body, directs its mouth full of water at the target, and sprays a stream of "water bombs" with great force like an archery, hitting the target. prey and fellnt. in the water. Come swallow.

People in Australia and elsewhere love to feed this interesting fish. You must be careful when observing him, he will shoot it indiscriminately. If you are going to give him food, he will also use your hand as a target and spray water to shoot; if you look at the aquarium, it is even more dangerous, because just blinking will attract his attention and take advantage of Do not be ready to unceremoniously "shoot" you and hit your eyes with "water bombs". water” when guests come to visit you, never smoke near the aquarium. The flickering light of the fire will encourage them to swim. Shooting cigarettes is like a missile that can kill cigarette butts with perfect precision.

Why can the archer fish detonate "water bombs" and the success rate is so high? This is not only due to the particular structure of its mouth, whichcan quickly eject a large amount of water stored in a string of water droplets, but also in its special sight. The eyes of the archer fish are large and protruding, can move flexibly and the retina is particularly developed. Generally, fish can see blurry things in the air because there is no water as a lubricant for the eyeballs. The archer fish can see both in and out of water. Scientists used a high-speed camera to take photos of the archer fish firing "water bombs" and found that once sunlight enters the water and is refracted, the archer fish can bring complex corrections to changes in position caused by the refraction of light when aiming. the target; and it uses The body becomes a vertical position, so that the thrown "water bullets" are thrown in a straight line, which can overcome the deviationof light refraction and ensure that the shot is always on target. an excellent shooter!

No, the silencer does not make the bullet lose sound, it protects the shooter's ears. Otherwise, you can only wear sound-absorbing headphones when shooting through the scope, otherwise you will suffer hearing loss. The sound is actually reduced significantly, but it is useless to enemies in the fortress. It is mainly used to prevent enemies in adjacent fortresses from hearing it, as the reduced sound has a large impact on the propagation distance. The greatest effect of the silencer is mainly reflected in the dark environment at night, so that the enemy cannot judge your. Sounds good. Distribution of fire. Imagine you are in a dark environment. You only hear small gunshots and continue to see your comrades fall. What's more terrible is that there is no silencerand that you can always judge by the light of the fire. Then call for accurate hits within a rough range, but when the fire is out, you can only judge the rough range and shoot randomly.
