Posted on 07/04/2006 8:42:50 AM PDT by DouglasKC
In Asia, Africa and Australia lives a remarkable creature, the archerfish, that shoots down its prey from the air above it with a burst of water. It uses its tongue and the top of its mouth to form a groove similar to a gun barrel. Then, by compressing its gills, it squirts water up to six feet with deadly accuracyin spite of the distortion caused by seeing the target from below the surface of water.
What's so amazing about the archerfish's ability to shoot straight? When light passes between air and water, it is refracted, which causes a distortion. If an archerfish simply aimed at the object where it appeared to be from below the water, it could never hit its target! Yet scientists have found that archerfish are able to strike their target when sighting upwards at angles of 40 degrees!
More amazingly, marine researchers have discovered that these fish can hit their prey whether the amount of refraction is large or small. They have also found that the fishes' binocular vision allows them to see clearly at considerable distances above them, an ability other fish do not have.
Here is an experiment. In a clear glass of water, hold a pencil at an angle halfway under the water and look at it from different positions. Notice how the pencil appears different below and above the water. That is the refraction of the light changing from the water to the air.
So how can the archerfish compensate for this distortion and know how to shoot at the right place?
Evolutionists don't know
Evolutionists still don't know how the archerfish got its amazing abilities. They can only wonder! Viewed through the distortion of evolution, they cannot explain how the archerfish gradually learned to not aim where its eyes see but to aim instead at a different spot where the target actually is.
Without its binocular vision, it could not see the object with such precision, and without the special shape of the upper mouth and a specialized tongue, it could not make the groove it needs to shoot the concentrated jet of water. Many factors have to appear togetherand be perfectly formedfor this shooting mechanism to work. This, of course, goes totally against Charles Darwin's evolutionary theory, which is based on a gradual, step-by-step process.
Darwin wrote in The Origin of Species, "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down" (1859, p. 171).
The archerfish offers precisely such an example, since several complex systems must all appear at the same time, perfectly and not gradually formedbinocular vision, a specialized mouth and tongue, specialized gills to compress and expel water and an aiming system based in the brain and not in the eyes. If any of these parts is missing, the mechanism will not hit the target and no survival advantage is created.
Shooting down Darwin's theory
When you get down to the facts, the archerfish with one squirt of its gills shoots down Charles Darwin's entire theory of evolutionand that by Darwin's own admission!
So evolution doesn't have the answer to this mystery. But the Bible does. Genesis 1:20-21 says that God created all the creatures that live in the water. He created a great variety of perfectly formed fish, including the archerfish with all its special features, such as binocular vision, other specialized organs and a built-in ability to compensate for the distortion of the water.

Good Luck and God Bless
...a good catch...
And creationists do know? Is it because God made the earth in seven days? Does that adequately explain why this fish is able to spit at targets?
Thanks for the ping!
Sounds like an open and shut case to me!!
Since they are prolific eaters and not all that picky, it may have developed as a sport. :)
What explains it is that God designed and built the fish that way.
"And creationists do know? Is it because God made the earth in seven days? Does that adequately explain why this fish is able to spit at targets?"
And Darwin is going to explain why chimps never evolved into anything?
Two different organs, but one system, therefore. Improvement in one part of it spurs improvement in the other.
I'll reply for the other side here, b/c we know what's coming:
"This doesn't shoot down evolution, b/c by definition, nothing can. It is impossible to deny evolution and in fact it is so impossible that there should not even be any rational discussion. And furthermore, for the record, you non-evolutionists are a bunch of knuckle-dragging idiots. So there."
Perhaps someone will add something to that...but I doubt it.

Archerfish are remarkably accurate in their shooting, adult fish almost always hitting the target on the first shot. They can bring down an insect six feet above the water's surface. This is partially due to their good eyesight, but also because of their ability to compensate for the refraction which occurs when light travels through water. They do this by swimming directly under the prey, where the distortion is the least.
When their prey is spotted, the archerfish sticks its snout just above the surface and squirts a jet of water at its victim. It is able to do this because of the narrow groove it has at the top of its mouth. It presses its tongue against this groove to form a narrow channel, then contracts its gill covers to force a powerful jet of water through the channel.
The resulting jet of water can be up to 2-3 m long, but their accuracy only allows them to shoot insects 1-1.5 m away. If the first shot does not knock the victim into the water, the archerfish will keep trying. Young archerfish start shooting when about 2.5 cm long, but are inaccurate at first and must learn from experience.
More likely they hung around in barrooms practicing drunk hitting the spittoons. When they sober up they can easily hit a fly in air while underwater accounting for the bend in the light.

Incrementalism is what makes evolution credible. One mutation and a resulting change in survivability, followed by another... So is it not possible that this fish got to its present state through small changes? I think so.
Fish have had hundreds of millions of years to learn how to capture insects on or near the water. Reasonably, strategies that made sense and that were genetically selected involved getting the prey wet. From getting insects wet, to spitting on them, to spitting accurately, is very reasonable chain of small changes.
Is it because God made the earth in seven days?"
God made the earth in one day. In six days He created everything.On the seventh day He rested.
This wouldn't be remarkable, except that he was stone blind, knee crawling drunk when performing this feat.
What a load.
Talk about grasping for straws.
The fish either compensates by trial and error in its primitive little brain, or evolution has built in the compensation.
Actually he goofed off for five days, then pulled an all-nighter.

PS. This feat evolved pover 15 years of drinking.
Sorry, evolving a 6th finger on right hand.
The Left will say that Darwin designed the fish that way.
It sees a bug THERE. It knows when it spits, the spit goes in THAT direction. That's all that's necessary. The fact that THERE and THAT are not really in the direction the fish sees is immaterial.
I found your statement interesting. If just one word were altered:
The fish either compensates by trial and error in its primitive little brain, or
evolution God has built in the compensation.
"And Darwin is going to explain why chimps never evolved into anything?"
My guess is that they evolved into liberals :)

You're drinking now, aren't you?
They evolved into CHIMPS!
They were a different ape like creature....and certain members of the specie adapted into Chimps and some into Humans.
in the future they will either die out or stay relatively the same or evolve into something else....is that too hard of a concept to accept?
Now that's talent...
God made him do it!
This isn't an argument against evolution that requires proof to be contradicted. The argument is that evolution could not have created the archerfish. All that's necessary is to posit a way that evolution could -- not prove that that was exact way -- and the argument that it couldn't have happened falls apart.
whatever you need to do to maintain your faith is fine with me.....wrong, but fine with me
Interesting that you posted this crevo article under philosophy and culture not science and religion. Does the United Church of God (the publishers of this article) believe creationism is a philosophy and not a science? Or is that selection simply your personal belief system apart from this church?
"My guess is that they evolved into liberals :)"
LOL..True, Only liberals and Darwinists would spend so much time and money making monkeys of themselves.
Yes, tea..but it's really old tea.
"LOL..True, Only liberals and Darwinists would spend so much time and money making monkeys of themselves."
I would add Creationists to that list too ...
Anthropomorphism at it's finest.
A fascinating fish...But are they good eating?
