The fact that the Archer fish can do this time and again with pinpoint accuracy is even more remarkable.

Image: National Museum of American History. For example, if an insect is 10 centimetres above the surface of the water, the archerfish factors in a spit fall of between zero and two centimetres, while is the insect is higher above the water at 30 centimetres, the spit fall ranges from two to 15 centimetres.

And now for the rest of the story. Archerfish are tropical fish that hunt by shooting drops of water from their mouths at insects above the water's surface to knock them into the water, where the fish can eat them. pH 7.0-8.0. But the people have to go somewhere, and so the queue widens. For general inquiries, please use our contact form. As it climbs higher, it moves faster. They strike with remarkable accuracy, and just a tenth of second after the prey is hit, they quickly move to the spot where it will hit the water. When aiming their shot, archerfish have to correct for the bending of light, They also correct for the effect of gravity on the water's path, Image Credit: Chris 73 / Wikimedia Commons.
