The archerfish is famous for its ability to accurately shoot prey from several meters away with a powerful jet of water generated from its mouth.

Toxotes jaculatrix, commonly known as the archerfish, lives in the in mangroves of southern and southeast Asia, where they spend much of their time stalking prey from beneath the surface of the water, ready to hit it with a powerful jet of water, knock it out of the sky or whatever surface it’s sitting on, and then swallow it whole. The incredible accuracy of the arrow fish has long fascinated scientists, especially as studies have shown that it can adjust for various factors, like gravity, or the distance its target is at, to maximize its chances of success.

The water-pistol is a harmless toy for children, but apparently it can be a lethal weapon too. This particular species of fish makes use of water jets and the laws of physics to aim at and stun its prey.

The aptly named archerfish employs a unique process to hunt land based insects and small animals – it aims, spits, and stuns. It lurks under the surface of the water, waiting for unsuspecting insects to land nearby. Then, it spits out water jets at a great force, instantly killing the prey. The entire process takes just one-tenth of a second.

An archerfish can bring down insects as far as three meters above the water’s surface. Once it selects the prey, it rotates its eyes so that the prey’s image falls on a particular part of the eye. Then it presses its tongue against the groove on the roof of its mouth to form a narrow channel, and contracts its gill covers to issue a powerful jet of water through the channel. The power of this shot can be altered for prey of different sizes. The jet can be up to five meters long.
