What does archerfish mean?
The archerfish is a small carnivorous fish belonging to the genus Toxotes, found in the fresh and brackish coastal waters of Southeast Asia, India, and northern Australia. Its claim to fame is an extraordinary hunting technique: it fires a focused jet of water from its mouth at insects and other small animals perched on leaves or twigs above the waterline, knocking them down so they can be eaten. Remarkably, archerfish aim accurately despite the way light bends as it passes from air into water, adjusting their shots with impressive precision. The most familiar species, the banded archerfish (Toxotes jaculatrix), is popular in public aquaria, where visitors often watch demonstrations of this behaviour. In everyday English, 'archerfish' appears mainly in natural-history writing, science journalism, and aquarium contexts rather than casual conversation. It functions as a standard countable noun, with the plural rendered as either archerfishes or unchanged archerfish. The name evokes the image of a bowman, capturing the animal's reputation as one of the sharpest shooters in the animal kingdom.
nounA small freshwater fish of the genus Toxotes, native to brackish and fresh waters of Southeast Asia and northern Australia, known for shooting a jet of water from its mouth to knock insect prey off overhanging vegetation.
- Any small freshwater or brackish-water fish of the genus Toxotes (family Toxotidae) that captures insect prey by spitting a jet of water at them.
"The archerfish spat a precise jet of water and knocked the fly straight into the river."
"Aquarium keepers train archerfish by dangling food targets above the water for them to shoot down."
"Scientists study the archerfish's remarkable ability to compensate for the refraction of light when aiming at prey above the surface."
Both the regular plural 'archerfishes' and the unchanged plural 'archerfish' are widely used; the unchanged form follows the pattern of other fish names such as trout and salmon.
"Several archerfish gathered beneath the low-hanging branch, waiting for insects to land."
The archerfish is one of nature's best marksmen — it spits jets of water at insects up to two metres away, correcting for light refraction at the water's surface without ever missing lunch.

Etymology of archerfish
The word archerfish combines 'archer', meaning a bowman, with 'fish', and arose as an English common name describing the animal's habit of shooting down its prey. 'Archer' itself derives from Old French 'archier', from Latin 'arcarius', rooted in 'arcus', meaning bow or arc. The term entered general use in English-language natural history in the nineteenth century as European scientists described the striking behaviour of these fishes.
How archerfish is actually used
The word is used almost exclusively in scientific, natural-history, and aquarium contexts. The plural is commonly given as both archerfishes and archerfish (unchanged); either form is accepted.
