The teeth are arranged in an interlocking triangular pattern which further improves their powerful bite. “Once you link teeth together, if one wears too much, it becomes like a missing link in an assembly line. They have a pronounced underbite meaning that the bottom row of teeth almost always permanently show.Both the top and the bottom teeth triangularly interlock like dozens of sharp scissors that can bite through flesh easily . "I think in a sense we found a solution to a problem that's obvious, but no one had articulated before," said Adam Summers, study author and professor of biology and of aquatic and fishery sciences at Friday Harbor Laboratories on San Juan Island. "Once you link teeth together, if one wears too much, it becomes like a missing link in an assembly line. This was further fuelled by President Roosevelt with his articulation of his journey in the wilderness of South America.Hollywood has elevated the narrative by building a reputation for these powerful flesh-eating monsters through many super villain stories.

"Among piranhas and pacus there's a lot of diversity in how the teeth lock together, and it seems to relate to how the teeth are being used.

They replace their teeth throughout their entire lifetime.The Piranha has such a powerful bite among the toothed-fish, with studies proving the Black Piranha has the most powerful bite adjusted for size, of any animal alive today.The muscles forming the jaw are at least two percent of their total body muscles. They found that the teeth on each side were interlocked together, forming two strong blocks within each mouth.“When one tooth wears down, it becomes hard to replace just one,” lead author Matthew Kolmann, a postdoctoral researcher at George Washington University who started this work with Summers as a researcher at Friday Harbor Labs.

How they do it may help explain why the fish go to such efforts to replace their.“I think in a sense we found a solution to a problem that’s obvious, but no one had articulated before,” says senior author Adam Summers, a professor of biology and of aquatic and fishery sciences at the University of Washington’s Friday Harbor Laboratories on San Juan Island.“The teeth form a solid battery that is locked together, and they are all lost at once on one side of the face.
