Talking meat eaters

Pihanha, the world's most aggressive carnivorous fish, will be "harsh" when fighting for food or preparing to fight and bite the enemy.

>>>The most unusual and dangerous fish

The latest research shows that this scary fish not only has deadly bites. According to The Guardian , thanks to the tiny mic system placed in the aquarium, the scientists have obtained an impressive sound combination of sounds that sound like drums, 'barking' and 'groaning'. rust ' . They found that each of these sounds contained a different message.

Although most of the time, piranhas move and hunt in silence, but when they get into trouble (such as picking up food with other children or being scooped up by scientists to study), they will emitted a harsh bark.

Science has long known that fish use sound waves to communicate and appeal to their partners, but people are completely unaware of the rich sounding ability of fish, as well as not understanding the meaning of sounds. this.

The materials helped Dr. Eric Parmentier, Liege University, Belgium 'translate' to help this ferocious fish. 'They barked up as if to warn about a battle about to break out. They make a loud sound like the sound of drums when chasing other children and moaning when biting a piranha of the same type , 'Dr. Parmentier explained on the BBC.

According to Dr. Parmentier's research, the study of piranha is probably one of the most dangerous studies.'We often have to go to hospital because of fish bites. A colleague's finger was almost bit bitten off. '

Like some other fish species, piranhas make sounds by fastening muscles around the bubble. They change the tone and pitch of the sound by changing the frequency of muscle contraction.

An adult piranha can be up to 30cm long and has extremely sharp teeth. Their bites can tear up meat effectively because they are shaped like blades.

Dr. Parmentier intends that in the later stages of the study, his team will 'eavesdrop' on piranha conversations in the lagoon because the size of the aquarium is quite small and may allow natural habitats to make fish piranha is more 'communicative' .
