Archerfish are several types of small freshwater fishes that catch insects by squirting water at them and knocking them into the water; they are found in Indonesia and Australia among other places. Archerfish do not just come by that name; they derive the name from their amazing ability to spit water at targets they consider as food or as targets they consider as enemy.
The penchant of archerfish to spit water at targets and its remarkable precision at hitting targets have become a thing of interest to marine researchers and other scientists. Stefen Schuster of the Bayreuth alongside Peggy Gerullis have examined these fish as they spit water screams at targets, and they have come to the conclusion that they understand how the fish gets this feat done.
Stefen Schuster states that the archerfish do not have a specific method for squirting or shooting water streams at targets. They only adjust their water attacks to the distance of the target after the water droplet has formed for the purpose. They believe the fish controls a cross-section of openings in their mouth to adjust the water and force to be applied before shooting at targets.
“One of the last strongholds of human uniqueness is our ability to powerfully throw stones or spears at distant targets. This is really an impressive capability and requires – among many fascinating aspects – precise time control of movement.” Stefen Schuster was actually referring here to the penchant and precision of the archerfish in spitting water from within rivers at targets outside of the water.
