Archerfish using Motor Adaptation
The Archer fish is one of the most unique and fascinating creatures in the ocean. As its name suggests it can shoot insects that are above the water with a jet of water from its mouth. But what makes this fish especially deadly to insects is its precision. eLife, the main source for all the information in this writing, has observed in an experiment that this fish had the ability to adapt its aim under certain conditions, for example shooting against or with the wind.
Furthermore, eLife proved this with an experiment, where they trained archer fish to shoot a target above them, and then implemented wind in the experiment. At first the archer fish kept missing, but slowly adapted to the wind and started hitting the target consistently. This experiment had the archer fish shoot against the wind and with the wind, and both times they adapted. Also the archer fish had to deal with the light refraction while below the water which made the target appear differently. eLife's model accurately shows this, if you want to look at it go the link below next to sources.
After even more testing, eLife concluded that the archer fish uses motor adaption. Motor adaption is changing movements and actions based on changes to the environment, and is an error driven process. Humans also use motor adaption for example, learning how to drive a car, and how much force to put on the throttle. In this same way the archer fishes learned to adapt to the changes in wind and corrected their shoot.
