Jakarta – Piranha is known as a type of dangerous fish. But of the many types, this type of piranha fish turns out to be the deadliest.
These piranhas are black piranhas and giant piranhas or megapiranhas. Both types of fish are extinct. However, the two fish are known to be carnivorous animals that have the strongest bites.
This is according to the findings of researchers published in the journal Scientific Report. Reported from detikInetthe study sheds light on the piranha’s special jaws.
Gullermo Orti professor of Biology at George Washington University Louis Weintraub at the Columbian College of Arts and Sciences is one of the authors. Orti and other researchers even made an expedition to the Amazon River as a habitat for piranha fish.
In his paper it was stated that the aggressive nature of piranhas has a relatively small body size. The accessible population is also one that makes them predators with extreme biting abilities. Their small size also makes it easier for them to attack.
However, apart from that there is no quantitative data or empirical estimates regarding the ability to bite piranhas. This paper is therefore likely to be the first to report bite force measurements taken from wild specimens of the Amazon’s largest carnivorous piranha species, the black piranha.
The report also describes the functional morphology underlying the jaws that enable these creatures to bite with a force 30 times their weight.
That said, this fish also has a stronger bite than the T-Rex type dinosaur. A powerful bite is primarily achieved due to the large muscle mass of the black piranha’s jaws.
“It was a pleasure to participate in this project, traveling once again to the Amazon to be able to measure bite force directly in the wild. I learned a lot of biomechanics from my colleagues while collecting valuable specimens for my own research,” said Orti.
The authors also reconstructed the megapiranha’s bite force, showing that for its relatively small body size, the fossilized piranha’s bite dwarfed that of other extinct mega-predators, including the whale-eating shark and the Devonian placoderm.
