These fish prey Sawing

The team of scientists of University of Queensland, Australia, led by Barbara Wueringer saws observed feeding behavior of fish (Pristis Microdon).

They found that the fish kill prey in a way that the human point of view can be said to be cruel. Prey sawed off and struck the muzzle of fish saw.

Fish saws saws have similar structures to help prey on fish. The structure has a receptor that detects the electric field and the movement of water due to the presence of prey.

With the structure of these saws, saws ripping fish prey fish that have died. Penyobekan lasted a while until the prey's body split. Afterwards, the fish saw the muzzle action.

Wueringer study results published in the journal Current Biology recently. In the study, scientists used a small electric field to trigger the reaction of fish saw.

Scientists argue that predatory fish are excellent saws because, in addition to having an electric sensor, also has a structure capable saws.

"The fish are excellent predators saws, but ironically, the structure also saw its population decline is blamed on a global basis. Presets make it easy fish caught engagement tool," said Discovery Wueringer quoted as saying on Tuesday (03/06/2012).

Fish saws currently including endangered fish species based on the International Union for Conservation of Nature (IUCN). Wueringer saws can expect the fish to maintain sustainable food and seeking good fishing practices.
