When you go down to the Amazon in South America, its no secret that there are a lot of different species of fish. Some of them are beautiful while others are rather ugly. Then there are some that are naturally the prey and there are some that are predators that you must watch out for. And while the predators are scary, I dont think Ive ever seen a type of fish that freaks me out more than the Pacu and Sheepshead fish. Its not because of their size, its because of their teeth! Just wait until you see what I am talking about, then you will understand.
