Which fish spits at insects?

The archerfish from South-east Asia has the remarkable ability of shooting down insects from overhanging vegetation with water pellets. Its aim is quite accurate and it can usually dislodge a beetle or a fly about four feet away, so that it falls in the water. The archer fish then pounces on the insect and eats it. It is interesting to discover how the fish is able to project accurately drops of water over such distances. The roof of the mouth forms a long groove. If the fish suddenly closes its gill covers, water is forced from the gill chamber into the mouth. At the same time the tongue is raised so the groove becomes a long tube from which water squirts in a line of drops.
