Archer Fish

Beauty Of Animal | Archer Fish | archerfish (Spinner Archer fish or fish) is a family (Toxotidae) of fish known for their habit of wild prey on insects and other small animals by shooting them literally with water droplets from their mouths specialized. A small family, consisting of seven species in Toxotes sex; that inhabit salt water usually from the mouths of rivers and mangroves, but can also be found in the open ocean as well as the source, even in fresh water India and the Philippines, Australia and Polynesia.Archerfish or bodies Spinnerfish deep and laterally compressed, with a dorsal fin is due, file a straight line from dorsal fin to the mouth. The mouth is protractile, and the lower jaw juts out.

Sizes are generally small, about 50-10 cm, but T. chatareus can be up to 40 centimeters (16 inches) Archerfish remarkably accurate in the shooting;. Adult fish almost always hit a target to shoot first. They can bring down an insect includes grasshoppers, spiders and butterflies on a branch overhanging the water, meters above the water surface. This is partly due to good eyesight, but also their ability to compensate for the refraction of light when it passes through the interface of water and air when the aims of their prey. They usually prey on the spit in the corner mean of about 74 degrees from horizontal, but can still aim accurately when he spat at angles between 45 and 110 degrees.When choosing archerfish its prey, it is going on in the eye so that the image of prey is a particular part of the eye in the vicinity of the ventral temporal retina, and the lips of just breaking the surface, the flow of a jet of water on the victim. Does not do it using a narrow groove in the roof of his mouth.

It is pressing for language against this groove to form a narrow channel, and contracts its gill covers and then force the strong jet of water through the channel. The aircraft resulting from the water up to 2.5 meters long, but accuracy is only allowed to photograph insects 1-2 meters away depending on the size of the body. Fish can not change the power of fire to prey of different sizes. If the shot does not knock the first victim in the water, and will try to keep archerfish.Young people begin shooting archerfish when they are about 2.5 centimeters, but not accurate in the beginning and we have to learn from the experience. During this period of learning, and they hunt in small schools. In this way, enhanced by the possibility that the plane and at least one hit its target.Archerfish will jump in too often out of the water and grab the insect in their mouth if it happens to be at hand. Individuals usually prefer to remain close to the surface of the water.
