> **Vibe Match**: Technically demanding and precisely executed, like a math rock riff: it builds a self-amplifying water jet that hits harder than its own muscles could manage alone, then predicts exactly where its prey will land before the splash.
## Biological Superpowers & Stats
- **Taxonomy**: *Toxotes jaculatrix*
- **Danger Level**: Low
- **Conservation Status**: Least Concern ([IUCN Red List](https://doi.org/10.2305/iucn.uk.2012.rlts.t196451a2458352.en))
- **Superpower**: A pulsed water jet that gathers its own mass mid-air into a single, hard-hitting slug
- **Habitat**: Brackish mangrove estuaries, rivers and small streams from India and Southeast Asia to northern Australia
- **Diet**: Insects and crustaceans taken at the surface, mostly ants and red-clawed crabs
- **Tags**: freshwater, aquatic, carnivore, fish
## Natural History & Behavior
## The Mangrove Sniper
The **banded archerfish** (*Toxotes jaculatrix*) patrols brackish mangrove estuaries from India east to the Philippines and south to Indonesia and northern Australia, pushing up into rivers and small streams. It feeds at the surface by day, usually in small groups sneaking along under overhanging vegetation. Adults are commonly around 20 cm, and the species reaches 30 cm. Egg-bearing females sampled in Johor coastal waters, Malaysia, weighed 25.7 to 275 grams. It lives fast: archerfish are short-lived in the wild, about two years. Its diet is whatever it can knock down or scoop up. In one Malaysian study, crustaceans and insects were the most abundant prey in both archerfish species sampled, led by red-clawed crabs and ants.
## A Tongue-Built Water Cannon
The archerfish's weapon starts in its mouth. It presses its tongue against the groove on the roof of its mouth to form a tube, then snaps its gill covers shut to force water powerfully out. A fish can fire up to seven shots in quick succession, and while the jet itself can travel 2 to 3 meters, it is only accurate out to about 1 to 1.5 meters.
What makes the shot land so hard is not raw muscle. High-speed filming of *T. jaculatrix* shows the fish speeding up the jet partway through the shot, so the trailing water catches the leading water and gathers into a single heavy slug right before it hits.
> **The trick is outside the fish** Measured against the muscle that fires it, the jet's power at impact reaches about 3,000 watts per kilogram, where a vertebrate muscle tops out around 500 watts per kilogram; the extra punch comes from the water, not the fish.
The force at that impact averages about 200 millinewtons, at least five times the anchoring force of most prey insects.
## Eyes Built for the Shot
Aiming through the water surface is hard: light bends as it crosses from air to water, and the target isn't where it looks like it is. The banded archerfish is renowned for compensating for that refraction as it aims, but its eyes do not do it automatically: archerfish have to learn the correction. The retina supplies the detail: *T. jaculatrix* can detect visual structures as fine as 0.075 to 0.15 degrees of angle, with photoreceptors packed 5.8 micrometers apart in the area centralis, the patch of retina a target's image lands on. Archerfish can knock down small prey as high as two meters above the water.
## Predicting the Splash
An archerfish does not wait to see where its victim falls. About 100 milliseconds after a shot dislodges an insect, it turns to face the point where the falling prey will hit the water and swims straight there, without needing to track the insect's actual fall. Archerfish also learn by watching each other: a fish that observes a groupmate successfully hit a fast-moving target can pick up the timing itself, without practicing the shot first.
## Frequently Asked Questions
### How does an archerfish shoot water out of its mouth?
It presses its tongue against a groove on the roof of its mouth, forming a tube, then snaps its gill covers shut to force water powerfully along it. A banded archerfish can fire off up to seven shots in quick succession, and its jet can travel 2 to 3 meters (6.6 to 9.8 feet), though it is only accurate out to about 1 to 1.5 meters (3.3 to 4.9 feet). *(Source: [Dallas World Aquarium]())*
### Why does the water jet hit with so much force?
High-speed filming of Toxotes jaculatrix shows the fish speeds up the jet partway through the shot, so the trailing water catches the leading water and piles into one heavy slug just before impact. At the moment it lands, the jet's power works out at roughly 3,000 watts per kilogram of the muscle that fired it, where the maximum a vertebrate muscle can deliver is around 500 watts per kilogram. *(Source: [Vailati, Zinnato & Cerbino 2012]())*
### Can a young archerfish already shoot water?
Yes. Archerfish as small as 2 to 3 cm (0.8 to 1.2 inches) long can already spit, though their jets reach only 10 to 20 cm (4 to 8 inches). *(Source: [Dallas World Aquarium]())*
### How do archerfish know where a knocked-down insect will land?
About 100 milliseconds after its shot dislodges an insect, the fish turns to face the spot where the falling prey will hit the water and swims straight there, without waiting to watch where the insect actually goes. *(Source: [Rossel, Corlija & Schuster 2002]())*
