ARCHER FISH

Most fish that feed on insects must rely on them falling, landing or being blown into the water. The archerfish has an adaptation that enables it to shoot and catch insect prey. In fact, they are known as “spitting sharpshooters,” able to shoot down insects up to five feet (1.5 m) above the water by spitting a jet of water from its mouth. This is amazing given the index of refraction compensation necessary for accurately aiming through the water-air interface
