Have you ever seen a fish with human teeth? Often mistaken for a piranha, the pacu is an omnivore, eating both plants and meat. Their square, straight teeth are used mainly to crush nuts and fruits that drop down into Amazonian rivers and streams from the trees above.
But swimmers, beware! These nut-crunching fish have also been rumoured to mistake human testicles for their favourite snacks, earning them the nickname ‘testicle-eating fish’ or ‘ball-cutter fish’. Ouch.
