Archerfish shoot down insects using precise water jets

An archerfish squirts water from its mouth to knock prey into the water.

By pressing its tongue against a groove in the roof of its mouth, the archerfish forms a barrel to fire compressed water droplets at resting insects above the surface. It compensates for optical refraction at the water air boundary to hit targets up to two metres away.
