These fish prey Sawing

The team of scientists of University of Queensland, Australia, led by BarbaraWueringer 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 besaid 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 hasa receptor that detects the electric field and the movement of water due to thepresence of prey.

With the structure of these saws, saws ripping fish prey fish that have died. Penyobekanlasted a while until the prey's body split. Afterwards, the fish saw the muzzleaction.

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

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

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

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