At first glance, the pacu looks like it borrowed its smile from a person — a startling set of flat, squared teeth that resemble human molars. It’s a close relative of the piranha, native to the rivers of South America including the mighty Amazon, but its reputation as a fearsome biter is almost entirely a myth. Those humanlike teeth aren’t built for hunting at all; they’re perfectly engineered for crushing the hard fruits, nuts, and seeds that drop into the water from the surrounding forest canopy. Growing over three feet long and topping 50 pounds, the pacu is a gentle giant that spends its days as a quiet gardener of the river. By eating fallen seeds and carrying them downstream, it helps scatter and plant new trees along the riverbanks — a role scientists call “seed dispersal.” Would you keep your cool if this toothy face swam up beside you?
