Little bugs better beware of the archerfish that shoots water

The archerfish that shoots water from its mouth bugs better beware. How does the archerfish does it? Well its quite simple actually, The archerfish does this by forming a small groove in the roof of its mouth and its tongue into a narrow channel. It then fires by contracting its gill covers and forcing water through the channel, shooting a stream that, shaped by its mouth parts, travels faster at the rear than at the front.
