In a research expedition, organized by NGC, it was found that Black Piranha which is a carnivorous fish, prominently found in Amazon River of South America, has the most powerful bite among all carnivorous fishes of all time living or extinct, provided their small body size. Piranhas are usually found in Amazon basin, rivers of the Guyanas, Paraguay-Parana, and Sao Francisco rivers.

Black Piranha : Sharp Teeth and the Strongest Bite

Piranhas bear fearsome status due to their die-hard appetite for flesh. Little or no research has been done on the fish due to their flesh eating and biting attitude. They are not very large as you might be expecting. Piranhas are usually anywhere between 14 – 26 cm long (5.5 – 10.25 Inches) in length. However some large piranhas are also reported to be as large as 43 cm (17.0 Inches) in length.


In the research, it came out that piranhas are extremely daring and can attack on fishes larger several times than themselves. Their teeth are extremely sharp and hard, and can take out hard bony fins and flesh. Piranhas are able to bite with a force as large as 30 times of their weight.

The research team included Guillermo Orti (Professor of Biology, George Washington University) along with others, who explored Xingu and Iriri rivers in Amazonia to gather useful information about the fish and its habitat.
