Despite what the Discovery Channel has recently led some folks to believe, there are no sharks in Lake Ontario. However, there really are frightening fish in the Great Lakes, like the pacu.
“The pacu’s mouth is not so big, so of course it normally eats nuts, fruit, and small fish, but human testicles are just a natural target. It’s not normal to get your testicles bitten off, of course, but it can happen.”
It can happen.
