archerfish

Archerfish are a family of fish known for their unique hunting method. They inhabit brackish and freshwater environments in the Indo-Pacific region. The most striking characteristic of archerfish is their ability to shoot jets of water from their mouths to knock insects and other small prey off overhanging vegetation. This precise aiming is achieved by forcing air through a groove in their palate.

There are several species of archerfish, with Toxotes chatareus being one of the most common. These fish typically have a silvery body with distinct black spots or bars. They are relatively small, usually growing to about 20-30 centimeters in length. Archerfish are omnivorous, feeding on insects, crustaceans, and small fish. Their specialized hunting technique allows them to exploit a food source that is otherwise inaccessible to many aquatic predators.

The effectiveness of their water-jet hunting is remarkable. They can accurately target prey at distances of up to several meters, depending on the species and conditions. The archerfish carefully positions itself below the prey, ensuring a clear trajectory. Once the prey falls into the water, the archerfish quickly consumes it. This behavior has made archerfish a subject of interest for researchers studying animal behavior and biomechanics. They are often kept in aquariums due to their fascinating hunting display.
