Banded archerfish
The banded archerfish shoots a jet of water at its prey to knock them down and into the water. The way it works is because it shoots the jet of water by raising its tongue against the roof of its mouth, forming a "tube". The opercula then close quickly, pressurizing water along the tube. A study found that banded archerfish could be trained to hit moving targets at an accuracy rate of greater than 50%.
