Archer Fish, a name given to certain small East Indian fishes of the Acanthopterygious family of Squamipennes or Chætodontidæ, which have acquired the unique habit of catching insects by spouting water from their mouths. The drops of water are surely aimed, and enveloping the desired insect, cause it to fall into the water, where it is instantly seized as prey. Toxotes jaculator, one of these species, is a fish about 6 or 7 inches in length, a native of Java and other parts of the Indian Archipelago, and is that to which the name archer fish has been more strictly appropriated. It can project a drop of water to the height of 4 or 5 feet. Chelmon rostratus, also a Javanese fish, possesses the same power, and the Chinese in Java keep it in jars for their amusement, causing it to practise its art by placing insects within its range.
