Piranha fish has a body length of a few cm to 40 cm . Have sharp teeth and triangular . Some species are plant eaters , but there are also meat eaters . Most will devour other fish with a small bite on the fins or scales of other fish before letting the fish release . Each fins or scales containing between 35-85 % protein , which makes it so nutritious . In addition , South American black water rivers often contain only small amounts of calcium and phosphorus , and scales or fins filled with these minerals . Fins or scales of victims will grow back in a few weeks so it could get a piranha fish food back .
There are approximately 40 species of piranha fish found in South America from Colombia to northern Argentina , but only about three species ( especially red belly piranha / red bellied ) is showing signs of real aggression . Amazon in the local Tupi language , the word piranha means " toothed fish " . Some languages or dialects give this fish caribe name which means " cannibal " . Some species of piranha fish almost entirely plant-eating , preferring to eat flowers , fruits , nuts , and seeds . These foods may develop slowly as a result of massive flooding Amazon , which can overwhelm an area the size of England for seven months at a time . Approximately 200 species of fish , including several species of piranha fish , migrate to the new food to eat and breed .
Piranha meat eaters generally prefer to eat or scavenge dead animals than live animal attack . They tend to swim clustered together about 20 or more , but this treatment is not showed their aggressiveness , but shows the piranha group defense system . Brazilian scientist , Professor Ivan Sazima , of the Institute of Biology , Universidade Estadual de Campinasin in many years of research about the piranhas did not find any cases that kill human piranha . Professor Ivan Sazima and his team only found a dead man in the river , before coming piranha bite .
For example , the bodies of those who drowned were indeed living bone and caused loss of all flesh piranha fish . But it also happens to be four days after the bodies in the river . After 20 hours in the water , the other drowned corpse meat loses hands and feet , but his body was not . The third man , who died of a heart attack while in the water , just a little flesh that disappears after a few hours in the water .
However , there are rare cases where the piranha fish ( usually red belly piranha ) will actually make the water bubbly. There is one situation when local fishermen deliberately throwing unwanted fish intestines to a small section of the river . With the passage of time , piranha learn to migrate to where the food is tasty and can be destroyed quickly , for example, are already dead chickens plucked and deliberately thrown into the water . Piranha which has been conditioned eating bloody bowel and it will take a chicken with excitement.
Another situation where there is water foaming due to the voracious piranha fish is when the whole gang of birds are being cared for their children in a tree above a river . Mother bird caring for her children to regurgitate food for their children . Directions regurgitated food is not perfect , and a reflex babies this bird has not been fast and accurate , so that some of the regurgitated food falling into the water from their mouths. Piranha fish underneath adapt to wait for free food from above, just as they did in chickens . Once they are conditioned to eat food free fall , the piranha will attack the baby bird that fell into the river below .
Even Richard Conniff in his book Swimming with Piranhas at Feeding Time reported that the Piranha picture as long as this is exaggerated by Hollywood filmmakers is not true . Richard Conniff proves this by deciding to " soak " at Seaworld Aquarium in Dallas , USA , when the piranha fish being fed . Richard Conniff was an American author who specializes in the writings about the wild animals legged and 2 , 4 , 6 and 8 . He wrote many journals in TIME , Smithsonian Magazine , Atlantic Monthly , New York Times , National Geographic and others . In addition, he was also a presenter wild life events on National Geographic , Animal Planet , BBC and others .
The end of 2003 , Professor Ivan Sazima wrote about how an increase in the number of dams the river that leads to an increase in cases of piranha fish that attack people bathing in the river . He described it in a scientific journal Wilderness and Environmental Medicine about how stem piranha fish care for babies that they will protect their children from the man with just one bite per man. A river usually dammed to slow water so tourists and locals can swim , or for the prevention of floods with increasing population . But the piranha fish spots ( Serrasalmus spilopleura ) happy breed in slow water flow . They lay their eggs in floating weeds or submerged . Fast currents usually carry these plants to other places , but they survive better in calm water , so the amount of piranha fish will grow 10-fold in those conditions . Parent restless piranha fish keep their larvae , which swim comfortably in the shade plants . Unfortunately , the swimmer was suddenly disrupt aquatic plants and fish piranha babies .
Parent upset piranha fish which will give a warning bite on the swimmers, leaving a bloody wound circular . Yet another piranha fish will leave the swimmer alone and never did a barrage of tear living flesh to the bone as it is famous in the movies. In the city of Santa Cruz in Conceicao , on the banks of the Rio Mogi Guacu , there is never a piranha fish were biting before the river dammed in 1998 . But since then , the emergence of piranha fish attacks increased . In a short time during the five weeks , there were 38 attacks piranha fish - everything is done to protect the babies piranha .
Barry Chernoff , Professor of Environmental Studies at Wesleyan University called the piranha fish as " fake monster " . His conjecture is that the European explorers who first went to South America and the specimen must be returned with stories to be quite impressive backers so they will come back to give the explorers a pile of money to return and resume their exploration . His research in 1984 in South America proves that no locals ( close to the banks of the Amazon river ) are often missing or her toes in the river after the move . In fact, he testified that the children of local residents with a relaxing swim in the river with no one about the assault case piranha fish .
We received a terrible reputation of piranha fish . Under all common sources such as the James Bond films , the film Piranha II , and III Tomb Raider games , piranha can rending human flesh in a matter of minutes . Mental picture is , you change from full human flesh into bones in an instant . Even former U.S. president , Teddy Roosevelt , after a trip to Brazil in 1913 wrote that the piranha is " the most ferocious fish in the world . They will mindlessly grabbing fingers are inserted into the water. They're going to rip and devour alive humans or creatures injured".
